Shift Solenoid: Service and Repair

Control and Shift Solenoids Replacement

Removal Procedure





1. Remove the transmission oil pan and filter.

2. Important: Do not remove the valve body for this procedures. Removal of the 1-2 accumulator is necessary only if servicing the pressure control solenoid.

Remove the 1-2 accumulator if necessary.
3. Disconnect the internal wiring harness electrical connectors from these components:
^ Transmission fluid pressure switch (1)
^ 1-2 shift control solenoid (2)
^ 2-3 shift control solenoid (3)
^ Pressure control solenoid (4)
^ TCC PWM solenoid (5)
^ 3-2 control solenoid (6)





4. Remove the pressure control solenoid retainer.
5. Remove the pressure control solenoid.





6. Remove the 1-2 and 2-3 shift solenoid retainers.
7. Remove the 1-2 and 2-3 shift solenoids.





8. Remove the 3-2 control solenoid retainer.
9. Remove the 3-2 control solenoid.

Installation Procedure

2. Install the 3-2 control solenoid retainer.





3. Install the 1-2 and 2-3 shift solenoids.
4. Install the 1-2 and 2-3 shift solenoid retainers.





5. Install the pressure control solenoid.Ensure that the electrical tabs are facing outboard.

Notice: Refer to Fastener Notice in Service Precautions.
