PERFORMANCE TESTS
PRELIMINARY INSPECTION

Ensure a thorough explanation of when and how transaxle malfunction occurs is received from customer. Check
fluid level and condition. Retrieve diagnostic trouble codes. See appropriate TOYOTA ELECTRONIC
CONTROLS article.

Proceed as necessary. If no DTCs are present, proceed with symptom diagnosis. See TROUBLE
SHOOTING . Perform STALL SPEED TEST under TORQUE CONVERTER, TIME LAG TEST and
HYDRAULIC PRESSURE TESTS as needed. After repairs are completed, perform ROAD TEST to confirm
repairs.

ROAD TEST

NOTE: Perform test at normal operating fluid temperature of 122-176°F (50-80°C).

"D" Position

1. Shift transaxle into Drive. Hold accelerator pedal constant at full throttle. Check 1-2, 2-3, and 3-4 upshift
and lock-up points. See appropriate table in SHIFT SPEED SPECIFICATIONS .

NOTE: There is no overdrive lock-up when coolant temperature is below 140°F

(60°C) or when vehicle speed is 6 MPH less than the set cruise control
speed. There is no lock-up when brake pedal is depressed.

If no 1-2 upshift occurs, check lower valve body control valves or

shift solenoid.

 2000 Toyota Celica GT
2000 AUTOMATIC TRANSMISSIONS Toyota U340E & U341E Overhaul

If no 2-3 upshift occurs, check lower valve body control valves or

shift solenoid.
If no 3-4 upshift occurs, check 3-4 shift valve or shift solenoid.
If all shift points are incorrect, check upper valve body, lower valve
body control valves and 3-4 shift valve.
If all lock-up points are incorrect, check lock-up relay valve or shift
solenoid.

2. Use procedure outlined in step 1 to check for shock and slip between 1-2, 2-3, and 3-4 upshifts. If shock
is harsh, line pressure may be too high. Check accumulator or check ball.
3. Drive vehicle Drive during lock-up or Overdrive. Check for abnormal noise and vibration.

NOTE: Check for cause of abnormal noise and vibration must be made with
extreme care as problem could be due to an unbalanced drive axle,
differential, tire, torque converter, etc.

4. While driving in Drive, confirm correct kickdown vehicle speed limits for 2-1, 3-2, 4-3 shift points.
Check for abnormal shock and slip at kickdown.
5. Check lock-up function. Drive vehicle in Overdrive ("D" position) with lock-up on. Hold vehicle speed
steady at 37 MPH. Lightly depress accelerator pedal. Ensure engine RPM does not change abruptly.
Large increase in engine RPM indicates lock-up function is faulty.

"2" Position

1. Shift transaxle to manual 2nd gear. Drive vehicle with accelerator pedal held constantly at full throttle.
Ensure 1-2 upshift points take place and are operating properly.

NOTE: In "2" position there will be no lock-up to 2nd gear.

2. While driving in manual 2nd gear, release accelerator pedal and check engine braking effect. If there is no
engine braking effect, 2nd brake is defective. Check for abnormal noise and shock at acceleration and
deceleration.

"L" Position

While driving in Low, ensure there is no upshift to 2nd gear. While driving in Low, release accelerator pedal. If
there is no engine braking effect, 1st/reverse brake is defective. Check for abnormal noise during acceleration
and deceleration.

"R" Position

Shift transaxle into Reverse. Accelerate in Reverse from a stop at full throttle. Ensure slipping does not occur.

"P" Position

2. Block front and rear wheels. Connect scan tool to Data Link Connector (DLC3) to monitor engine RPM.
Apply parking and service brakes. Start engine. Shift transaxle into Drive. Fully depress accelerator
pedal. Release pedal within 10 seconds.
3. Record highest engine RPM. Compare reading obtained to specification. Stall speed should be 2220-2520
RPM for Celica and 2130-2550 RPM for ECHO. Repeat test in Reverse.
4. If stall speed is same for both positions, but lower than specified RPM, engine output may be insufficient
or stator one-way clutch is not operating properly.

NOTE: If stall speed RPM is more than 600 RPM less than specification, torque
converter may be faulty.

5. If stall speed in Drive is higher than specifications, forward clutch may be slipping, No. 2 one-way clutch
may not be operating properly, or line pressure is too low.
6. If stall speed in Reverse is higher than specifications, reverse clutch may be slipping, 1st/reverse brake
may be slipping or line pressure is too low.
7. If stall speed in Reverse and Drive is higher than specifications, line pressure is too low, incorrect fluid
level exists or No. 2 one-way clutch is not operating properly.

HYDRAULIC PRESSURE TESTS

CAUTION: Perform test at normal operating fluid temperature of 122-176°F (50-80°C).

1. Ensure transaxle fluid is at operating temperature. Raise and support vehicle. Remove transaxle case line
pressure test plug. See Fig. 6 . Install hydraulic pressure gauge. Lower vehicle.
2. Fully apply parking brake. Block all wheels. Start engine and ensure idle speed is 700-800 on Celica, or
650-750 RPM on ECHO. Shift transaxle into Drive. Read and record line pressure at idle. Fully apply
brakes. Depress accelerator pedal to floor. DO NOT apply full throttle for more than 10 seconds.
3. Measure highest line pressure. Refer to specifications in appropriate LINE PRESSURE
SPECIFICATIONS table. Repeat test in Reverse. If pressures exceed specifications in all ranges,
regulator valve or shift solenoid SLT in upper valve body is defective. Ensure no TP sensor related
trouble codes are present.
4. If pressures in both positions are lower than specifications, oil pump, regulator valve or shift solenoid
SLT is defective. Ensure no TP sensor related trouble codes are present.
5. If pressure is lower than specifications in Drive only, forward clutch is defective or Drive circuit has a
fluid leak. If pressure is lower than specifications in Reverse only, reverse clutch is defective, 1st/reverse
brake is defective or Reverse circuit has a fluid leak.

TIME LAG TEST

CAUTION: Perform this test at normal operating fluid temperature of 122-176°F (50-
80°C). Allow one minute between tests. Record 3 measurements and
average results.

1. If selector lever is actuated with engine idling, a time lag will be noted before shock can be felt. This test
is used for checking condition of No. 2 one-way clutch, forward clutch, reverse clutch and 1st/reverse
brake.
2. Apply parking brake. Connect scan tool to DLC3 to monitor engine RPM. Start engine. Ensure idle speed
is 700-800 RPM on Celica or 650-750 RPM on ECHO, with transaxle in Neutral and A/C off. Shift
transaxle from Neutral into Drive. Use a stop watch to measure elapsed time between shifting lever until
shock is felt.
3. Standard time lag is less than 1.2 seconds. Repeat test to measure time lag for Neutral to Reverse.
Standard time lag is less than 1.5 seconds. If Neutral to Drive time lag is longer than specified, line
pressure is too low, forward clutch may be worn or No. 2 one-way clutch is not operating properly.
4. If Neutral to Reverse position time lag is longer than specified, reverse clutch may be worn, 1st/reverse
brake may be worn or line pressure is too low.

COMPONENT TESTS
TORQUE CONVERTER

NOTE: Torque converter is a sealed unit and is serviced as complete assembly.

Perform following tests to check for defective converter. Torque converter and
transaxle cooler must be thoroughly cleaned and flushed if transaxle is
