SYSTEM DESCRIPTION
• When an engine and A/T integrated control signal (engine torque) equivalent to the engine drive force is
transmitted from the ECM to the TCM, the TCM controls the line pressure solenoid valve.
This line pressure solenoid controls the pressure regulator valve as the signal pressure and adjusts the pres- M
sure of the operating oil discharged from the oil pump to the line pressure most appropriate to the driving
state.
• The TCM has stored in memory a number of patterns for the optimum line pressure characteristic for the N
driving state.
• In order to obtain the most appropriate line pressure characteristic to meet the current driving state, the TCM
controls the line pressure solenoid current value and thus controls the line pressure.

Back-up Control (Engine Brake)


When the select operation is performed during driving and the A/T is
shifted down, the line pressure is set according to the vehicle speed.

PCIA0009E

During Shift Change


The necessary and adequate line pressure for shift change is set.
For this reason, line pressure pattern setting corresponds to engine
torque and gearshift selection. Also, line pressure characteristic cor-
responds to engine speed, during engine brake operation.

driving force. On a down-slope, automatic shift-down to 4GR, 5GR or 6GR gear controls to gain optimum
engine brake. A
When Driving on a Curve
• In driving condition where acceleration, deceleration, or lateral acceleration continues, it corrects gear selec-
tion in order to keep a smooth vehicle speed during the curve and to give an adequate driving force at the B
curve end.
- When acceleration pedal is quickly released at curve entrance etc, it prevents an unnecessary shift-up.
- On braking operation at curve entrance, it gives an early shift-down according to the deceleration. C
- In a sporty driving condition, it selects lower gear early even on a light braking operation, giving greater
importance on driving force.
• TCM receives the side G sensor signal from the ABS actuator and electric unit (control unit). It locks to 4GR,
5GR or 6GR position in moderate cornering or to 3GR position in sharp cornering based on this signal. This TM
prevents any upshift and kick down during cornering, maintaining smooth vehicle travel.

JSDIA1362GB

DS Mode J
• Changes to the shift schedule that mainly utilizes the high engine speed zone when ASC is active.
• DS mode can be switched according to the following method.
- When the selector lever is in the “D” position, shifting the selector lever to manual shift gate enables switch- K
ing to DS mode.
- When in DS mode, shifting the selector lever to the main gate enables to cancel DS mode.
- After switching to manual mode with paddle shifter, switching to DS mode can not be enabled even when the
L
selector lever is shifted to the manual gate. (With paddle shifter)

SYSTEM DESCRIPTION
Manual Mode
• The TCM receives the manual mode signal, non-manual mode signal, manual mode shift up signal and
manual mode shift down signal from unified meter and A/C amp. via CAN communication line. The TCM
shifts shift pattern control to the manual mode based on these signals, and then shifts the A/T by operating
each solenoid valve according to the shift operation of the driver.
• The TCM prohibits the manual mode while being in fail-safe mode due to an A/T malfunction, etc. Refer to
TM-152, "Fail-Safe".
• The TCM transmits the manual mode shift refusal signal to the unified meter and A/C amp. if the TCM
refuses the transmission from the driving status of vehicle when the selector lever shifts to UP or DOWN
side. The unified meter and A/C amp. blinks shift indicator on the combination meter and sounds the buzzer
to indicate the driver that the shifting is not performed when receiving this signal. However, the TCM does
not transmit the manual mode shift refusal signal in the conditions as per the following.

LOCK-UP CONTROL
< SYSTEM DESCRIPTION > [7AT: RE7R01A (VQ37VHR)]

JSDIA0847GB

Lock-up released
• In the lock-up released state, the torque converter clutch control valve is set into the unlocked state by the
torque converter clutch solenoid and the lock-up apply pressure is drained.
in this way, the torque converter clutch piston is not coupled.
Lock-up Applied
• In the lock-up applied state, the torque converter clutch control valve is set into the locked state by the
torque converter clutch solenoid and lock-up apply pressure is generated.
In this way, the torque converter clutch piston is pressed and coupled.
Smooth Lock-up Control
When shifting from the lock-up released state to the lock-up applied state, the current output to the torque con-
verter clutch solenoid is controlled with the TCM. In this way, when shifting to the lock-up applied state, the
torque converter clutch is temporarily set to the half-clutched state to reduce the shock.
Half-clutched State
• The current output from the TCM to the torque converter clutch solenoid is varied to steadily increase the
torque converter clutch solenoid pressure.
In this way, the lock-up apply pressure gradually rises and while the torque converter clutch piston is put into
half-clutched states, the torque converter clutch piston operating pressure is increased and the coupling is
completed smoothly.
Slip Lock-up Control
• In the slip region, the torque converter clutch solenoid current is controlled with the TCM to put it into the
half-clutched state. This absorbs the engine torque fluctuation and lock-up operates from low speed.
This raises the fuel efficiency for 2GR, 3GR, 4GR, 5GR, 6GR and 7GR.

SHIFT LOCK SYSTEM
< SYSTEM DESCRIPTION > [7AT: RE7R01A (VQ37VHR)]
SHIFT LOCK SYSTEM
A
System Description INFOID:0000000010578867

• Shift lock prevents an unintentional start of the vehicle that may be caused by an incorrect operation while B
selector lever is in the “P” position.
• Selector lever can be shifted from the “P” position to another position when the following conditions are sat-
isfied.
- Ignition switch ON C
- Stop lamp switch is ON (brake pedal is depressed)
- Selector lever knob button is pressed
SHIFT LOCK OPERATION AT “P” POSITION TM

When Brake Pedal Is Not Depressed (No Shift Operation Allowed)


The shift lock solenoid (A) inside the shift lock unit is not energized if E
the brake pedal is not depressed while the ignition switch is ON.
The lock plate (B) lowers according to the downward movement of
the position pin (C) when the selector button (D) is pressed, and
presses only slider B (E) into the shift lock unit. Slider A (F) located F
below the lock plate prevents the downward movement of the lock
plate with the spring force. The selector lever cannot be shifted from
the “P” position for this reason. G
However, slider A is forcibly pressed into the shift lock unit, allowing
the selector lever to shift if the shift lock release button is pressed.
JSDIA0119ZZ
H
When Brake Pedal Is Depressed (Shift Operation Allowed)
The shift lock solenoid (A) inside the shift lock unit is energized and
the relative positions of sliders A (B) and B (C) are maintained when I
the brake pedal is depressed while the ignition switch is ON.
The lock plate (D) lowers according to the downward movement of
the position pin (E), thrusting away sliders A and B, when the selec-
tor button (F) is pressed. J
The position pin lowers to the position that allows shift operation for
this reason. As a result, the selector lever can be shifted out of the P
position. K

JSDIA0120ZZ

L
OPERATION AT OTHER THAN “P” POSITION
The shift lock function will not operate at any position other than “P”
because the lock plate (A) is only set for the “P” position. Accord-
ingly, the selector lever can be shifted to any position regardless of M
the brake operation.
The position pin (B) enters the “P” position thrusting away the lock
plate when the selector lever is shifted to the “P” position. Then, the N
shift mechanism is locked when the selector button (C) is released.

O
JSDIA0121ZZ

“P” POSITION RETAINING MECHANISM (IGNITION SWITCH LOCK) P


When ignition switch is not in the ON position, power is not applied to the shift lock solenoid in the shift lock
unit. This causes shift lock state, and then “P” position is retained.
When an actuating system in the shift lock unit has a malfunction, selector lever is unable to operate from the
“P” position even when pressing the brake pedal with the ignition switch ON. However, when pressing the shift
lock release button, slider A is forcibly pressed into the shift lock unit. This allows shift lock to be released and
selector lever enables the select operation from the “P” position.
CAUTION:

ON BOARD DIAGNOSTIC (OBD) SYSTEM
< SYSTEM DESCRIPTION > [7AT: RE7R01A (VQ37VHR)]
ON BOARD DIAGNOSTIC (OBD) SYSTEM
A
Diagnosis Description INFOID:0000000010578870

The A/T system has two self-diagnostic systems. B


The first is the emission-related on board diagnostic system (OBD-II) performed by the TCM in combination
with the ECM. A malfunction is indicated by the MIL (malfunction indicator lamp) and is stored as a DTC in the
ECM memory and in the TCM memory.
The second is the TCM original self-diagnosis indicated by the TCM. A malfunction history is stored in the C
TCM memory. The detected items are overlapped with OBD-II self-diagnostic items. For details, refer to TM-
157, "DTC Index".
OBD FUNCTION TM
The ECM provides emission-related on board diagnostic (OBD-II) functions for the A/T system.
One function is to receive a signal from the TCM used with OBD-related parts of the A/T system. The signal is
sent to the ECM when a malfunction occurs in the corresponding OBD-related part. E
The other function is to indicate a diagnostic result by means of the MIL (malfunction indicator lamp) on the
instrument panel. Sensors, switches and solenoid valves are used as sensing elements.
The MIL automatically illuminates in “One or Two Trip Detection Logic” when a malfunction is sensed in rela-
F
tion to A/T system parts. For details, refer to EC-147, "DIAGNOSIS DESCRIPTION : 1st Trip Detection Logic
and Two Trip Detection Logic".

U1000 CAN COMM CIRCUIT
< DTC/CIRCUIT DIAGNOSIS > [7AT: RE7R01A (VQ37VHR)]
U1000 CAN COMM CIRCUIT
Description INFOID:0000000010578877

CAN (Controller Area Network) is a serial communication line for real-time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent malfunction detection ability.
Many electronic control units are equipped onto a vehicle, and each control unit shares information and links
with other control units during operation (not independently). In CAN communication, control units are con-
nected with 2 communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission
with less wiring. Each control unit transmits/receives data but selectively reads required data only.

ECU DIAGNOSIS INFORMATION


TCM
Reference Value INFOID:0000000010578984

VALUES ON DIAGNOSIS TOOL


• The CONSULT electrically displays shift timing and lock-up timing (that is, operation timing of each sole-
noid).
Check for time difference between actual shift timing and the CONSULT display. If the difference is notice-
able, mechanical parts (except solenoids, sensors, etc.) may be malfunctioning. Check mechanical parts
using applicable diagnostic procedures.
• Shift schedule (which implies gear position) displayed on CONSULT and that indicated in Service Manual
may differ slightly. This occurs because of the following reasons:

- Actual shift schedule has more or less tolerance or allowance
- Shift schedule indicated in Service Manual refers to the point where shifts start
- Gear position displayed on CONSULT indicates the point where shifts are completed
• Display of solenoid valves on CONSULT changes at the start of shifting, while gear position is displayed
upon completion of shifting (which is computed by TCM).
NOTE:
The following table includes information (items) inapplicable to this vehicle. For information (items) applicable
to this vehicle, refer to CONSULT display items.

Fail-Safe INFOID:0000000010578986

TCM has the electrical fail-safe mode. The mode is divided into a maximum of 3 phases (1st Fail-Safe, 2nd
Fail-Safe and Final Fail-Safe) and functions so that the operation can be continued even if the signal circuit of
the main electronically controlled input/output parts is damaged.
Even if the electronic circuit is normal, the fail-safe mode may start under special conditions (such as when the
brake pedal is depressed suddenly from a hard wheel spin status to stop the rotation of wheels). In this case,
turn the ignition switch OFF and back to ON after 5 seconds to resume the normal shift pattern.

Consequently, the customer's vehicle may already return to the normal condition. Refer to TM-9, "Work Flow".
A
The mode that the vehicle can stop safely, to prompt the driver to stop if the malfunction occurs and to shift to
1st fail-safe
2nd Fail-Safe early. It shifts to 2nd Fail-Safe or Final Fail-Safe after the vehicle stopped.
The mode that the vehicle shifts to Final Fail-Safe without changing the behavior, by identifying the malfunc- B
2nd fail-safe
tioning parts in the condition that the driving force required for the driving is secured.
• Selects the shifting pattern that the malfunctioning parts identified at 1st and 2nd Fail-Safe are not used, and
Final fail-safe then secure the driving force that is required for the driving.
• The mode that the shifting performance does not decrease by normal shift control.

PRECAUTIONS
< PRECAUTION > [7AT: RE7R01A (VQ37VHR)]

PRECAUTION A
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT B
PRE-TENSIONER" INFOID:0000000010578991

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along C
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. TM
Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this
Service Manual.
WARNING: E
Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in
the event of a collision that would result in air bag inflation, all maintenance must be performed by
F
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see “SRS AIR BAG”. G
• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-
vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors. H
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
Always observe the following items for preventing accidental activation. I
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the
ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with
a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing J
serious injury.
• When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the
battery, and wait at least 3 minutes before performing any service.
K
Precaution for Procedure without Cowl Top Cover INFOID:0000000010578992

When performing the procedure after removing cowl top cover, cover
L
the lower end of windshield with urethane, etc to prevent damage to
windshield.

PRECAUTIONS
< PRECAUTION > [7AT: RE7R01A (VQ37VHR)]
General Precautions INFOID:0000000010578993

• Turn ignition switch OFF and disconnect the battery cable


from the negative terminal before connecting or disconnect-
ing the A/T assembly harness connector. Because battery
voltage is applied to TCM even if ignition switch is turned
OFF.

SEF289H

• Perform “DTC (Diagnostic Trouble Code) CONFIRMATION


PROCEDURE” after performing each TROUBLE DIAGNOSIS.
If the repair is completed DTC should not be displayed in the
“DTC CONFIRMATION PROCEDURE”.
• Always use the specified brand of ATF. Refer to MA-17, "FOR
NORTH AMERICA : Fluids and Lubricants" (For North America),
MA-18, "FOR MEXICO : Fluids and Lubricants" (For Mexico).
• Use lint-free paper not cloth rags during work.
• Dispose of the waste oil using the methods prescribed by law, ordi-
nance, etc. after replacing the ATF.
• Before proceeding with disassembly, thoroughly clean the outside
JSBIA1315ZZ
of the transmission. It is important to prevent the internal parts from
becoming contaminated by dirt or other foreign matter.
• Disassembly should be done in a clean work area.
• Use lint-free paper or towels for wiping parts clean. Common shop rags can leave fibers that could interfere
with the operation of the transmission.
• Place disassembled parts in order for easier and proper assembly.
• All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.
• Gaskets, seals and O-rings should be replaced any time the A/T is disassembled.
• It is very important to perform functional tests whenever they are indicated.
• The valve body contains precision parts and requires extreme care when parts are removed and serviced.
Place disassembled valve body parts in order for easier and proper assembly. Care will also prevent springs
and small parts from becoming scattered or lost.
• Properly installed valves, sleeves, plugs, etc. will slide along bores in valve body under their own weight.
• Before assembly, apply a coat of recommended ATF to all parts. Apply petroleum jelly to protect O-rings and
seals, or hold bearings and washers in place during assembly. Never use grease.
• Extreme care should be taken to avoid damage to O-rings, seals and gaskets when assembling.
• Clean or replace ATF cooler if excessive foreign material is found in oil pan or clogging strainer. Refer to TM-
170, "Service Notice or Precaution".
• When the A/T drain plug is removed, only some of the ATF is drained. Old ATF will remain in torque con-
verter and ATF cooling system.
Always follow the procedures under “Changing” when changing ATF. Refer to TM-174, "Changing".
• Occasionally, the parking gear may be locked with the torque insufficiently released, when stopping the vehi-
cle by shifting the selector lever from “D” or “R” to “P” position with the brake pedal depressed.
In this case, the shock with a thud caused by the abrupt release of torque may occur when shifting the selec-
tor lever from “P” position to other positions.
However, this symptom is not a malfunction which results in the damage of parts.
Service Notice or Precaution INFOID:0000000010578994

ATF COOLER SERVICE


If ATF contains frictional material (clutches, bands, etc.), or if an A/T is repaired, overhauled, or replaced,
inspect and clean the A/T fluid cooler mounted in the radiator or replace the radiator. Flush cooler lines using
cleaning solvent and compressed air after repair. For A/T fluid cooler cleaning procedure, refer to TM-177,
"Cleaning". For radiator replacement, refer to CO-16, "Exploded View".

Precautions for Removing Battery Terminal INFOID:0000000010769757

A
• When removing the 12V battery terminal, turn OFF the ignition
switch and wait at least 30 seconds.
NOTE: B
ECU may be active for several tens of seconds after the ignition
switch is turned OFF. If the battery terminal is removed before ECU
stops, then a DTC detection error or ECU data corruption may
occur. C
• For vehicles with the 2-batteries, be sure to connect the main bat-
tery and the sub battery before turning ON the ignition switch.
NOTE: TM
If the ignition switch is turned ON with any one of the terminals of
main battery and sub battery disconnected, then DTC may be
SEF289H

detected.
• After installing the 12V battery, always check "Self Diagnosis Result" of all ECUs and erase DTC. E
NOTE:
The removal of 12V battery may cause a DTC detection error.

Whenever an A/T is replaced, the A/T fluid cooler mounted in the radiator must be inspected and cleaned. B
Metal debris and friction material, if present, can become trapped in the A/T fluid cooler. This debris can con-
taminate the newly serviced A/T or, in severe cases, can block or restrict the flow of ATF. In either case, mal-
function of the newly serviced A/T may result.
Debris, if present, may build up as ATF enters the cooler inlet. It will be necessary to back flush the cooler C
through the cooler outlet in order to flush out any built up debris.
CLEANING PROCEDURE

Check foreign materials in oil pan to help determine causes of mal-
function. If the ATF is very dark, smells burned, or contains foreign
particles, the frictional material (clutches, band) may need replace-
ment. A tacky film that will not wipe clean indicates varnish build up. F
Varnish can cause valves, servo, and clutches to stick and can
inhibit pump pressure.
• If frictional material is detected, perform A/T fluid cooler G
cleaning. Refer to TM-177, "Cleaning".

Oil Pan
Check foreign materials in oil pan to help determine causes of mal-
M
function. If the ATF is very dark, smells burned, or contains foreign
particles, the frictional material (clutches, band) may need replace-
ment. A tacky film that will not wipe clean indicates varnish build up.
Varnish can cause valves, servo, and clutches to stick and can N
inhibit pump pressure.

Diagnostic Work Sheet INFOID:0000000010579082

DESCRIPTION
There are many operating conditions that may cause a malfunction
of the transmission parts. By understanding those conditions prop-
erly, a quick and exact diagnosis can be achieved.
In general, customers have their own criteria for a problem. There-
fore, it is important to understand the symptom and status well
enough by asking the customer about the concerns carefully. In
order to systemize all the information for the diagnosis, prepare the
question sheet referring to the question points.

SYSTEM DESCRIPTION
• When an engine and A/T integrated control signal (engine torque) equivalent to the engine drive force is
transmitted from the ECM to the TCM, the TCM controls the line pressure solenoid valve.
This line pressure solenoid controls the pressure regulator valve as the signal pressure and adjusts the pres- M
sure of the operating oil discharged from the oil pump to the line pressure most appropriate to the driving
state.
• The TCM has stored in memory a number of patterns for the optimum line pressure characteristic for the N
driving state.
• In order to obtain the most appropriate line pressure characteristic to meet the current driving state, the TCM
controls the line pressure solenoid current value and thus controls the line pressure.

Back-up Control (Engine Brake)


When the select operation is performed during driving and the A/T is
shifted down, the line pressure is set according to the vehicle speed.

PCIA0009E

During Shift Change


The necessary and adequate line pressure for shift change is set.
For this reason, line pressure pattern setting corresponds to engine
torque and gearshift selection. Also, line pressure characteristic cor-
responds to engine speed, during engine brake operation.

driving force. On a down-slope, automatic shift-down to 4GR, 5GR or 6GR gear controls to gain optimum
engine brake. A
When Driving on a Curve
• In driving condition where acceleration, deceleration, or lateral acceleration continues, it corrects gear selec-
tion in order to keep a smooth vehicle speed during the curve and to give an adequate driving force at the B
curve end.
- When acceleration pedal is quickly released at curve entrance etc., it prevents an unnecessary shift-up.
- On braking operation at curve entrance, it gives an early shift-down according to the deceleration. C
- In a sporty driving condition, it selects lower gear early even on a light braking operation, giving greater
importance on driving force.
• TCM receives the side G sensor signal from the ABS actuator and electric unit (control unit). It locks to 4GR,
5GR or 6GR position in moderate cornering or to 3GR position in sharp cornering based on this signal. This TM
prevents any upshift and kick down during cornering, maintaining smooth vehicle travel.

DS Mode J
• Changes to the shift schedule that mainly utilizes the high engine speed zone when ASC is active.
• DS mode can be switched according to the following method.
- When the selector lever is in the “D” position, shifting the selector lever to manual shift gate enables switch- K
ing to DS mode.
- When in DS mode, shifting the selector lever to the main gate enables to cancel DS mode.
- After switching to manual mode with paddle shifter, switching to DS mode can not be enabled even when the
L
selector lever is shifted to the manual gate. (With paddle shifter)

LOCK-UP CONTROL
< SYSTEM DESCRIPTION > [7AT: RE7R01B (VK50VE)]

PCIA0014E

Lock-up released
• In the lock-up released state, the torque converter clutch control valve is set into the unlocked state by the
torque converter clutch solenoid and the lock-up apply pressure is drained.
in this way, the torque converter clutch piston is not coupled.
Lock-up Applied
• In the lock-up applied state, the torque converter clutch control valve is set into the locked state by the
torque converter clutch solenoid and lock-up apply pressure is generated.
In this way, the torque converter clutch piston is pressed and coupled.
Smooth Lock-up Control
When shifting from the lock-up released state to the lock-up applied state, the current output to the torque con-
verter clutch solenoid is controlled with the TCM. In this way, when shifting to the lock-up applied state, the
torque converter clutch is temporarily set to the half-clutched state to reduce the shock.
Half-clutched State
• The current output from the TCM to the torque converter clutch solenoid is varied to steadily increase the
torque converter clutch solenoid pressure.
In this way, the lock-up apply pressure gradually rises and while the torque converter clutch piston is put into
half-clutched states, the torque converter clutch piston operating pressure is increased and the coupling is
completed smoothly.
Slip Lock-up Control
• In the slip region, the torque converter clutch solenoid current is controlled with the TCM to put it into the
half-clutched state. This absorbs the engine torque fluctuation and lock-up operates from low speed.
This raises the fuel efficiency for 2GR, 3GR, 4GR, 5GR, 6GR and 7GR.

SHIFT LOCK SYSTEM
< SYSTEM DESCRIPTION > [7AT: RE7R01B (VK50VE)]
SHIFT LOCK SYSTEM
System Description INFOID:0000000010579114

• Shift lock prevents an unintentional start of the vehicle that may be caused by an incorrect operation while
selector lever is in the “P” position.
• Selector lever can be shifted from the “P” position to another position when the following conditions are sat-
isfied.
- Ignition switch ON
- Stop lamp switch is ON (brake pedal is depressed)
- Selector lever knob button is pressed
SHIFT LOCK OPERATION AT “P” POSITION
When Brake Pedal Is Not Depressed (No Shift Operation Allowed)
The shift lock solenoid (A) inside the shift lock unit is not energized if
the brake pedal is not depressed while the ignition switch is ON.
The lock plate (B) lowers according to the downward movement of
the position pin (C) when the selector button (D) is pressed, and
presses only slider B (E) into the shift lock unit. Slider A (F) located
below the lock plate prevents the downward movement of the lock
plate with the spring force. The selector lever cannot be shifted from
the “P” position for this reason.
However, slider A is forcibly pressed into the shift lock unit, allowing
the selector lever to shift if the shift lock release button is pressed.
JSDIA0119ZZ

When Brake Pedal Is Depressed (Shift Operation Allowed)


The shift lock solenoid (A) inside the shift lock unit is energized and
the relative positions of sliders A (B) and B (C) are maintained when
the brake pedal is depressed while the ignition switch is ON.
The lock plate (D) lowers according to the downward movement of
the position pin (E), thrusting away sliders A and B, when the selec-
tor button (F) is pressed.
The position pin lowers to the position that allows shift operation for
this reason. As a result, the selector lever can be shifted out of the P
position.

JSDIA0120ZZ

OPERATION AT OTHER THAN “P” POSITION


The shift lock function will not operate at any position other than “P”
because the lock plate (A) is only set for the “P” position. Accord-
ingly, the selector lever can be shifted to any position regardless of
the brake operation.
The position pin (B) enters the “P” position thrusting away the lock
plate when the selector lever is shifted to the “P” position. Then, the
shift mechanism is locked when the selector button (C) is released.

JSDIA0121ZZ

“P” POSITION RETAINING MECHANISM (IGNITION SWITCH LOCK)


When ignition switch is not in the ON position, power is not applied to the shift lock solenoid in the shift lock
unit. This causes shift lock state, and then “P” position is retained.
When an actuating system in the shift lock unit has a malfunction, selector lever is unable to operate from the
“P” position even when pressing the brake pedal with the ignition switch ON. However, when pressing the shift
lock release button, slider A is forcibly pressed into the shift lock unit. This allows shift lock to be released and
selector lever enables the select operation from the “P” position.
CAUTION:

< SYSTEM DESCRIPTION > [7AT: RE7R01B (VK50VE)]
ON BOARD DIAGNOSTIC (OBD) SYSTEM
Diagnosis Description INFOID:0000000010579117

The A/T system has two self-diagnostic systems.


The first is the emission-related on board diagnostic system (OBD-II) performed by the TCM in combination
with the ECM. A malfunction is indicated by the MIL (malfunction indicator lamp) and is stored as a DTC in the
ECM memory and in the TCM memory.
The second is the TCM original self-diagnosis indicated by the TCM. A malfunction history is stored in the
TCM memory. The detected items are overlapped with OBD-II self-diagnostic items. For details, refer to TM-
455, "DTC Index".
OBD FUNCTION
The ECM provides emission-related on board diagnostic (OBD-II) functions for the A/T system.
One function is to receive a signal from the TCM used with OBD-related parts of the A/T system. The signal is
sent to the ECM when a malfunction occurs in the corresponding OBD-related part.
The other function is to indicate a diagnostic result by means of the MIL (malfunction indicator lamp) on the
instrument panel. Sensors, switches and solenoid valves are used as sensing elements.
The MIL automatically illuminates in “One or Two Trip Detection Logic” when a malfunction is sensed in rela-
tion to A/T system parts. For details, refer to EC-1254, "DIAGNOSIS DESCRIPTION : 1st Trip Detection Logic
and Two Trip Detection Logic".

U1000 CAN COMM CIRCUIT
A
Description INFOID:0000000010579124

CAN (Controller Area Network) is a serial communication line for real-time application. It is an on-vehicle mul- B
tiplex communication line with high data communication speed and excellent malfunction detection ability.
Many electronic control units are equipped onto a vehicle, and each control unit shares information and links
with other control units during operation (not independently). In CAN communication, control units are con-
nected with 2 communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission C
with less wiring. Each control unit transmits/receives data but selectively reads required data only.

TCM
Reference Value INFOID:0000000010579233

VALUES ON DIAGNOSIS TOOL


• The CONSULT electrically displays shift timing and lock-up timing (that is, operation timing of each sole-
noid).
Check for time difference between actual shift timing and the CONSULT display. If the difference is notice-
able, mechanical parts (except solenoids, sensors, etc.) may be malfunctioning. Check mechanical parts
using applicable diagnostic procedures.
• Shift schedule (which implies gear position) displayed on CONSULT and that indicated in Service Manual
may differ slightly. This occurs because of the following reasons:

- Actual shift schedule has more or less tolerance or allowance
- Shift schedule indicated in Service Manual refers to the point where shifts start
- Gear position displayed on CONSULT indicates the point where shifts are completed
• Display of solenoid valves on CONSULT changes at the start of shifting, while gear position is displayed
upon completion of shifting (which is computed by TCM).
NOTE:
The following table includes information (items) inapplicable to this vehicle. For information (items) applicable
to this vehicle, refer to CONSULT display items.

Fail-Safe INFOID:0000000010579235

TCM has the electrical fail-safe mode. The mode is divided into a maximum of 3 phases (1st Fail-Safe, 2nd
Fail-Safe and Final Fail-Safe) and functions so that the operation can be continued even if the signal circuit of
the main electronically controlled input/output parts is damaged.
Even if the electronic circuit is normal, the fail-safe mode may start under special conditions (such as when the
brake pedal is depressed suddenly from a hard wheel spin status to stop the rotation of wheels). In this case,
turn the ignition switch OFF and back to ON after 5 seconds to resume the normal shift pattern.

Protection Control INFOID:0000000010579236

The TCM becomes the protection control status temporarily to protect the safety when the safety of TCM and
transmission is lost. It automatically returns to the normal status if the safety is secured. L
The TCM has the following protection control.
REVERSE INHIBIT CONTROL
Intercepts the torque transmission and shift to the neutral status if the selector lever is shifted to “R” position M
while the vehicle moves forward at the vehicle speed 10 km/h (7 MPH) or more.

Malfunction detection condition Vehicle speed: 10 km/h (7 MPH) or more N


Control at malfunction Neutral
• Vehicle speed: 8 km/h (5 MPH) or less
Normal return condition O
• Engine speed: 2,200 rpm or less
• The torque transmission cannot be performed
Vehicle behavior
• There is a shock just before a vehicle stop
P
1ST ENGINE BRAKE PROTECTION CONTROL
Controls the engine brake so as not to make effective by turning the front brake solenoid output to OFF when
each solenoid becomes the electricity pattern of 1st engine brake during driving at the vehicle speed 25 km/h
or more in any positions other than “R” position or 1GR.

PRECAUTIONS
< PRECAUTION > [7AT: RE7R01B (VK50VE)]

PRECAUTION A
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT B
PRE-TENSIONER" INFOID:0000000010579240

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along C
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. TM
Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this
Service Manual.
WARNING: E
Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in
the event of a collision that would result in air bag inflation, all maintenance must be performed by
F
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see “SRS AIR BAG”. G
• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-
vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors. H
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
Always observe the following items for preventing accidental activation. I
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the
ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with
a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing J
serious injury.
• When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the
battery, and wait at least 3 minutes before performing any service.
K
Precaution for Procedure without Cowl Top Cover INFOID:0000000010579241

When performing the procedure after removing cowl top cover, cover
L
the lower end of windshield with urethane, etc to prevent damage to
windshield.

PRECAUTIONS
< PRECAUTION > [7AT: RE7R01B (VK50VE)]
General Precautions INFOID:0000000010579242

• Turn ignition switch OFF and disconnect the battery cable


from the negative terminal before connecting or disconnect-
ing the A/T assembly harness connector. Because battery
voltage is applied to TCM even if ignition switch is turned
OFF.

SEF289H

• Perform “DTC (Diagnostic Trouble Code) CONFIRMATION


PROCEDURE” after performing each TROUBLE DIAGNOSIS.
If the repair is completed DTC should not be displayed in the
“DTC CONFIRMATION PROCEDURE”.
• Always use the specified brand of ATF. Refer to MA-18, "FOR
MEXICO : Fluids and Lubricants".
• Use lint-free paper not cloth rags during work.
• Dispose of the waste oil using the methods prescribed by law, ordi-
nance, etc. after replacing the ATF.
• Before proceeding with disassembly, thoroughly clean the outside
of the transmission. It is important to prevent the internal parts from
SEF217U
becoming contaminated by dirt or other foreign matter.
• Disassembly should be done in a clean work area.
• Use lint-free paper or towels for wiping parts clean. Common shop rags can leave fibers that could interfere
with the operation of the transmission.
• Place disassembled parts in order for easier and proper assembly.
• All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.
• Gaskets, seals and O-rings should be replaced any time the A/T is disassembled.
• It is very important to perform functional tests whenever they are indicated.
• The valve body contains precision parts and requires extreme care when parts are removed and serviced.
Place disassembled valve body parts in order for easier and proper assembly. Care will also prevent springs
and small parts from becoming scattered or lost.
• Properly installed valves, sleeves, plugs, etc. will slide along bores in valve body under their own weight.
• Before assembly, apply a coat of recommended ATF to all parts. Apply petroleum jelly to protect O-rings and
seals, or hold bearings and washers in place during assembly. Never use grease.
• Extreme care should be taken to avoid damage to O-rings, seals and gaskets when assembling.
• Clean or replace ATF cooler if excessive foreign material is found in oil pan or clogging strainer. Refer to TM-
468, "Service Notice or Precaution".
• When the A/T drain plug is removed, only some of the ATF is drained. Old ATF will remain in torque con-
verter and ATF cooling system.
Always follow the procedures under “Changing” when changing ATF. Refer to TM-472, "Changing".
• Occasionally, the parking gear may be locked with the torque insufficiently released, when stopping the vehi-
cle by shifting the selector lever from “D” or “R” to “P” position with the brake pedal depressed.
In this case, the shock with a thud caused by the abrupt release of torque may occur when shifting the selec-
tor lever from “P” position to other positions.
However, this symptom is not a malfunction resulting the damage of parts.
Service Notice or Precaution INFOID:0000000010579243

ATF COOLER SERVICE


If ATF contains frictional material (clutches, bands, etc.), or if an A/T is repaired, overhauled, or replaced,
inspect and clean the A/T fluid cooler mounted in the radiator or replace the radiator. Flush cooler lines using
cleaning solvent and compressed air after repair. For A/T fluid cooler cleaning procedure, refer to TM-177,
"Cleaning". For radiator replacement, refer to CO-43, "Exploded View".

INSPECTION AFTER REMOVAL


Check foreign materials in oil pan to help determine causes of mal- I
function. If the ATF is very dark, smells burned, or contains foreign
particles, the frictional material (clutches, band) may need replace-
ment. A tacky film that will not wipe clean indicates varnish build up. J
Varnish can cause valves, servo, and clutches to stick and can
inhibit pump pressure.
• If frictional material is detected, perform A/T fluid cooler
cleaning. Refer to TM-475, "Cleaning". K

function. If the ATF is very dark, smells burned, or contains foreign
particles, the frictional material (clutches, band) may need replace-
ment. A tacky film that will not wipe clean indicates varnish build up.
