Service Procedure:
- Attach a GDS and select DTC Analysis and A/T menu. Record the DTC and description. Delete the DTC.
- From the GDS home screen, select Data Analysis and A/T menu and the solenoid parameters shown below. If the solenoids show:
- Continuous and changing output while driving, the wiring currently has no open/short circuits. Go to Step 4.
- No continuous and changing output, go to Step 3.
- Visually check the wiring harness between the PCM and transmission for a damaged wire or open/short circuit. Check for a damaged pin or pin not fully inserted into the connector.
- If damage exists, repair or replace the control wiring and drive the vehicle to confirm the repair.
- If no damage or open/short circuit, go to Step 4.

- For UD, OD, 26 and 35R solenoids:
- Use a 10mm socket and ratchet to remove two bolts to the upper solenoid support. Remove the support.
- For SS-A, TC and PC solenoids:
- Use a 5mm hex socket and remove three hex bolts that secure the solenoid support. Remove the support.
- Record the 8-digit code on the solenoid.
