Test TC-141F - Governor Pressure Not Equal To Target @ 15-20 Psi
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
NOTE:
Perform TEST TC-141A before proceeding. For connector terminal identification, see CONNECTOR IDENTIFICATION . For appropriate wiring diagram, see WIRING DIAGRAMS . Perform VERIFICATION TEST VER-1A after each repair.
- Turn engine off. Drain and remove transmission oil pan. Inspect pan for burnt oil and debris. Repair transmission as necessary. If transmission is okay, go to next step.
- Using an external ohmmeter, measure resistance between terminal No. 1 (Violet wire) on solenoid connector and terminal No. 5 on solenoid pack connector (transmission side). If resistance is 10 ohms or more, repair open governor pressure solenoid circuit. If resistance is less than 10 ohms, go to next step.
- Measure resistance between terminal No. 2 (Blue wire) on solenoid connector and terminal No. 1 on solenoid pack connector (transmission side). If resistance is 10 ohms or more, repair open transmission relay output circuit. If resistance is less than 10 ohms, replace governor pressure solenoid.
