Circuit/System Testing
- Ignition OFF, remove the line pressure test hole plug and install the J 21867 to the transmission.
- Perform the LINE PRESSURE CHECK . Verify the transmission line pressure gage is within the range specified in the Line PC Solenoid Valve Pressure table. Refer to SOLENOID VALVE PRESSURE .
- If not within the specified range, repair as necessary. Refer to FLUID PRESSURE HIGH OR LOW for further diagnosis.
- Ignition OFF, remove the control solenoid (w/body and TCM) valve assembly.
- Install the DT-47825 to the control solenoid (w/body and TCM) valve assembly. Refer to CONTROL SOLENOID VALVE AND TRANSMISSION CONTROL MODULE ASSEMBLY SOLENOID PERFORMANCE TEST for detailed instructions.
- Perform the CONTROL SOLENOID VALVE AND TRANSMISSION CONTROL MODULE ASSEMBLY SOLENOID PERFORMANCE TEST . A pressure change should occur.
- If a pressure change does not occur, replace the control solenoid (w/body and TCM) valve assembly.
- Inspect for the following conditions and repair/replace as necessary:
- The control valve lower body assembly for sticking valves, damage, scored bores, or debris
- The clutch select valve 3 for damage
