Automatic Transmission/Transaxle: Testing and Inspection

HYDRAULIC PRESSURE TEST
1. Warm up the engine until the automatic transmission fluid temperature is 80 - 100°C.
2. Jack up the vehicle so that the wheels are free to turn.











3. Connect the special tools (2,942 kPa (427 psi) oil pressure gauge [MD998330] and joints [MD998332, MD9989001) to each pressure discharge port.

NOTE:
2ND: Second brake pressure port
UD: Underdrive clutch pressure port
LR: Low and reverse brake pressure port
DA: Torque converter apply pressure port
DR: Torque converter release pressure port
RV: Reverse clutch pressure port
OD: Overdrive clutch pressure port

4. Measure the hydraulic pressure at each port under the conditions given in the standard hydraulic pressure table, and check that the measured values are within the standard value ranges.
5. If a value is outside the standard range, correct the problem while referring to the hydraulic pressure test diagnosis table.
