Torque Converter Clutch Solenoid: Service and Repair

Torque Converter Clutch Pulse Width Modulation (TCC PWM) Solenoid Replacement
Removal Procedure
1. Remove the case side cover.





2. Disconnect and reposition the electrical connectors from the following:
^ The internal mode switch if equipped
^ The 2-3 shift solenoid valve assembly (315B)
^ The Transmission Fluid Pressure (TFP) manual valve position switch (395)





3. Important: Do NOT remove the bolt (205) that holds the oil pump together.

Remove the oil pump bolts (206, 207).





4. Remove the oil pump (200) from the valve body (300).





5. Disconnect the torque converter clutch pulse width modulation (TCC PWM) solenoid electrical connector.
6. Remove the TCC PWM solenoid retaining clip (314F).
7. Remove the TCC PWM solenoid (334).
8. Remove the O-ring seals (305, 306) from the TCC PWM solenoid valve (334) ONLY if they are damaged.

Installation Procedure





1. Install new O-ring seals (305, 306) onto the TCC PWM solenoid valve (334) if they were removed.
2. Install the TCC PWM solenoid (334).
3. Hold the TCC PWM solenoid in place while installing the retaining clip (314F).
4. Connect the TCC PWM solenoid electrical connector.





5. Install the oil pump (200) to the valve body (300).





6. Notice: Refer to Fastener Notice in Service Precautions.

Install the oil pump bolts (206, 207).
^ Tighten the bolts (207) to 12 Nm (106 inch lbs.)
^ Tighten the bolts (206) to 16 Nm (12 ft. lbs.)





7. Reposition and connect the electrical connectors to the following:
^ The Transmission Fluid Pressure (TFP) manual valve position switch (395)
^ The 2-3 shift solenoid valve assembly (315B)
^ The internal mode switch if equipped
8. Install the case side cover.
