Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | Does the vehicle creep in P and/or N position? | Yes | Inspect or adjust the selector lever. (See SELECTOR LEVER INSPECTION.) (See SELECTOR CABLE ADJUSTMENT.)
No | Go to the next step.
2 | Stop the engine. Inspect the pressure control solenoid circuit. Is it normal? | Yes | Go to the next step.
No | Inspect for stuck pressure control solenoid. (See SOLENOID VALVE INSPECTION [JA5A-EL].) If pressure control solenoid is normal, inspect for open or short circuit between TCM terminal 2Y and pressure control solenoid terminal D.
3 | Remove the torque converter. Inspect the torque converter. (See ATX Workshop Manual.) Is the torque converter normal? | Yes | Overhaul the control valve body and repair or replace any malfunctioning parts. (See ATX Workshop Manual.) If any problem remains, replace or overhaul the transaxle and repair or replace any malfunctioning parts. (See AUTOMATIC TRANSAXLE REMOVAL/INSTALLATION [JA5A-EL].)
(See ATX Workshop Manual.)
No | Replace the torque converter.
4 | • Verify the test results.

  - If normal, return to the diagnostic index to service any additional symptoms.
  - If the malfunction remains, inspect the related Service Bulletins and/or On-line Repair Information and perform repair or diagnosis.

  • If the vehicle is repaired, troubleshooting is completed.
  • If the vehicle is not repaired or additional diagnostic information is not available, replace the TCM.
