Shift Solenoid: Service and Repair

Solenoids - Shift, Torque Converter Clutch, Electronic Pressure Control













Removal

1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to Jacking and Lifting Service and Repair.

2. Remove the transmission fluid pan and filter. For additional information, refer to Fluid Pan, Gasket and Filter Fluid Pan, Gasket and Filter.

3. NOTE: Main control assembly does not need to be removed for solenoid service.

Remove wire loom guide and protector.

- Carefully lift up on wire loom guide and protector and disengage the retaining pins from the solenoid clamps.





4. Disconnect the appropriate solenoid electrical connector.

1. Disconnect the electrical connectors from Shift Solenoid A (SSA), Shift Solenoid B (SSB), Shift Solenoid C (SSC) and Shift Solenoid D (SSD).

2. Disconnect the Torque Converter Clutch (TCC) solenoid electrical connector.

3. Disconnect the Electronic Pressure Control (EPC) solenoid electrical connector.





5. NOTICE: The Torque Converter Clutch (TCC) solenoid and converter modulator valve may pop out of its bore. This may damage the solenoid or converter modulator valve.

NOTICE: Shift Solenoid C (SSC) may pop out of its bore. This may damage the solenoid.

Remove the shift solenoids.

1. Remove the wire harness.

2. Remove the solenoid clamp screws.

3. Remove the solenoid clamp.

4. Remove the appropriate solenoid(s).





Installation

1. Install the new solenoid(s).





2. NOTE: The solenoid clamp must be installed in the TCC and EPC solenoid grooves, shift solenoid pockets and the No. 204 plug.

Install the solenoid clamp.

1. Position the solenoid clamp on the main control valve body.

2. Install the solenoid clamp screws.
- Tighten to 7 Nm (62 lb-in).





3. Connect the 6 solenoid electrical connectors.

1. Connect the SSA, SSB, SSC and SSD electrical connectors.

2. Connect the TCC solenoid electrical connector.

3. Connect the EPC solenoid electrical connector.





4. NOTICE: Excessive pressure may break the retaining pins.

Install the main control valve body wire loom.

- Align the retaining pins to the holes in the solenoid clamps and gently press in the main control valve body wire loom guide and protector.





5. Install the transmission fluid pan and filter. For additional information, refer to Fluid Pan, Gasket and Filter Fluid Pan, Gasket and Filter.
