Automatic transaxle is an electronically controlled transaxle with 4 forward speeds and one reverse speed.
Transaxle consists of clutches, mainshaft, countershaft, secondary shaft, shift control solenoid valves, clutch
pressure control solenoid valves and lock-up torque converter. See Fig. 2 .

Valve body assemblies consists of main valve body, regulator valve body, servo body and accumulator body.
Transaxle shifting and torque converter lock-up are controlled by the Powertrain Control Module (PCM). PCM
receives information from various inputs and uses this information to control solenoid valves for proper
transaxle operation.

Gearshift lever has 6 positions. When gearshift lever is moved, manual valve on main valve body is moved by
the shift cable. Gearshift lever also changes position of the transmission range switch, mounted near gearshift
lever. Transmission range switch delivers an input signal to PCM to indicate gearshift lever position. PCM uses
input signal, and operates shift control solenoid valves to control transaxle shifting.

When certain transaxle gear combinations are engaged by clutches, power is transmitted from mainshaft to
countershaft via secondary shaft to final drive gear, providing different gears.

Torque converter lock-up engages and transaxle mainshaft rotates at same speed as engine crankshaft when
transaxle is in "D" position (2nd, 3rd and 4th gears), or "D" position with overdrive mode off (3rd gear). Under
certain conditions, torque converter lock-up clutch is applied during deceleration when in 3rd and 4th gears.
PCM receives various input signals and operates clutch pressure control solenoid valves. Operating clutch
pressure control solenoid valves controls modulator pressure.

PCM contains a self-diagnostic system, which will store a Diagnostic Trouble Code (DTC) if a failure or
problem exists in the transaxle electronic control system. DTC can be retrieved to identify transaxle problem
area.

Overdrive (O/D) switch is located on end of gearshift lever. When ignition switch is turned to ON position,
overdrive is turned on. When overdrive switch is depressed, overdrive is turned off. O/D OFF indicator light,
located next to "D" position indicator on instrument panel, will illuminate. When overdrive is off, transaxle
selects only 1st, 2nd and 3rd gears. When overdrive is on, transaxle uses all 4 forward gears.

Transaxle is equipped with shift and key interlock systems. Shift interlock system prevents gearshift lever from
being moved from "P" position unless brake pedal is depressed and accelerator is in idle position. In case of a
malfunction, gearshift lever can be released by placing ignition key in release slot near gearshift lever. Key
interlock system prevents ignition key from being removed from ignition switch unless gearshift lever is in "P"
position. For additional information on shift and key interlock systems, see SHIFT INTERLOCK SYSTEMS
- CR-V article.

The A/T gear position indicator on instrument panel contains lights to indicate which position transmission
range switch on gearshift lever is in.

Disassembly

1. Clean all parts thoroughly in solvent or carburetor cleaner and dry them with compressed air. Blow out all
passages.
2. Do not use a magnet to remove the check ball, it may magnetize the ball.
3. Check all valves for free movement. If any fail to slide freely, see VALVE BODY REPAIR
PROCEDURES .
4. Replace the valve body as an assembly if any parts are worn or damaged. For valve spring specifications,
see Fig. 19 .

Valve Body Repair Procedures

NOTE: This repair is only necessary if one or more of the valves in a valve body do not
slide smoothly in their bores. Use this procedure to free the valves.

1. Soak a sheet of No. 600 abrasive paper in ATF for about 30 minutes.
2. Carefully tap the valve body so the sticking valve drops out of its bore. It may be necessary to use a small
screwdriver to pry the valve free. Be careful not to scratch the bore with the screwdriver.

lunes, 23 de enero de 2023 12:29:05 a. m. Page 26 © 2011 Mitchell Repair Information Company, LLC.
2002 Honda CR-V EX
2002 AUTOMATIC TRANSMISSIONS MCVA & MRVA Overhaul

3. Inspect the valve for any scuff marks. Use the ATF soaked No. 600 paper to polish off any burrs that are
on the valve, then wash the valve in solvent and dry it with compressed air.
4. Roll up half a sheet of ATF soaked No. 600 paper and insert it in the valve bore of the sticking valve. See
Fig. 20 . Twist the paper slightly, so that it unrolls and fits the bore tightly, then polish the bore by
twisting the paper as you push it in and out.

NOTE: The valve body is aluminum and doesn't require much polishing to remove
any burrs.

5. Remove the No. 600 paper. Thoroughly wash the entire valve body in solvent, then dry it with
compressed air.
6. Coat the valve with ATF, then drop it into its bore. See Fig. 21 . It should drop to the bottom of the bore
under its own weight. If not, repeat steps 4 and 5 , then retest. If the valve still sticks, replace the valve
body.
7. Remove the valve, and thoroughly clean it and the valve body with solvent. Dry all parts with compressed
air, then reassemble using ATF as a lubricant.

mark on the bottom of the waved plate.
3. Rotate the 1st and 2nd clutch waved plate about 60 degrees by holding the waved plate by its
circumference. Rotate the 3rd and 4th clutch waved plate about 72 degrees or 54 degrees apart from the
bottom. The dial indicator should be at the top (E) of a phase difference. See Fig. 43 . Do not rotate the
waved plate while holding its surface, always rotate it while holding it's circumference.
4. Read the dial indicator. The dial indicator reads the phase difference (C) of the waved plate between
bottom and top. Standard is .002" (.05 mm) minimum.
5. Rotate the 1st and 2nd clutch waved plate about 60 degrees from the top position, and rotate the 3rd and
4th clutch waved plate about 54 degrees or 72 degrees apart from the top. The dial indicator should be at
the bottom of a phase difference (F and H). Zero the dial indicator.
6. Measure the phase difference at the other 2 tops (G and I) of the waved plate by following steps 3 -5 .
7. If the 2 values of the 3 measurements are within the standard, the waved plate is okay. If the 2 values of
the 3 measurements are out of the standard, replace the waved plate.

Differential Assembly Bearing Preload

NOTE: If transmission housing, torque converter housing, differential carrier, bearings,


thrust shim, thrust washer or differential bearing outer races are replaced,
differential assembly bearing preload must be checked.

CAUTION: DO NOT heat transmission housing to more than 212°F (100°C), or housing
may be damaged.

1. Using heat gun, heat transmission housing around differential bearing outer race and thrust shim to 212°F
(100°C). Tap differential bearing outer race from transmission housing. Remove thrust shim and thrust
washer, located below differential bearing outer race, from transmission housing.
2. Allow transmission housing to cool to room temperature. Install the 76 mm thrust shim in transmission
housing. Install 76.2 mm thrust washer. Using hammer and bearing race installer, install differential
bearing outer race in transmission housing. Ensure differential bearing outer race is fully seated in
transmission housing, and there is no clearance between outer race, thrust washer, thrust shim and
transmission housing.

CAUTION: Ensure torque converter housing gasket is installed when checking


differential assembly bearing preload.

3. Install gasket and dowel pins (if removed) on torque converter housing. DO NOT apply sealer at this
time. Install differential assembly in torque converter housing. Install transmission housing with hanger
and harness clamp brackets on torque converter housing without mainshaft, countershaft and secondary
shaft installed.
4. Install and tighten transmission housing-to-torque converter housing bolts to 32 ft. lbs. (44 N.m) in
sequence. Rotate differential assembly several turns to seat bearings.
5. Install Preload Adapter (07HAJ-PK40201) into differential assembly. See Fig. 54 . Install INCH-lb.
torque wrench on preload adapter. Measure differential assembly bearing preload by checking starting
torque required to rotate differential assembly in both directions at room temperature.
6. Differential assembly bearing preload should be within specification. See DIFFERENTIAL
ASSEMBLY BEARING PRELOAD SPECIFICATIONS table.
7. If differential assembly bearing preload is not within specification, select proper thickness thrust shim
from appropriate thrust shim selection table to obtain correct reading. See Fig. 52 and Fig. 53 .
