Shift Solenoid: Service and Repair
Control and Shift Solenoids ReplacementRemoval Procedure
1. Remove the transmission oil pan and filter.
Important: Do not remove the valve body for the following procedures. Removal of the 1-2 accumulator is necessary only if servicing the pressure control solenoid.
2. Remove the 1-2 accumulator if necessary.
3. Disconnect the internal wiring harness electrical connectors from the following 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
