Wiring Harness: Service and Repair




Internal Harness Service





Removal

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

2. Disconnect vehicle harness from the transmission case (16-pin) connector.





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

4. Remove the main control valve body wire loom.
- Carefully lift up on the wire loom guide and protector, and disengage the retaining pins from the solenoid clamps.





5. Disconnect the solenoid electrical connectors.

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

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

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





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

NOTICE: Shift solenoids may pop out of their bore. This may damage the solenoids.

Remove the EPC and SSB solenoids.

1. Remove the solenoid clamp screws.

2. Remove the solenoid clamp.

3. Remove the EPC and SSB solenoids.





7. NOTICE: Do not pry on the other wires or damage the connector case surface.

Disconnect the Turbine Shaft Speed (TSS) sensor electrical connector from the transmission case (16-pin) electrical connector.

1. Disconnect the TSS sensor electrical connector.

2. Remove from the TSS sensor wire locator.





8. NOTICE: Do not overstretch the retaining spring. Overstretching can damage the spring.

Remove the transmission case (16-pin) electrical connector retaining spring.





9. NOTICE: Do not damage the connector or harness.

Remove the transmission case (16-pin) electrical connector.

- Compress the tabs on the transmission case (16-pin) electrical connector.

- Push the transmission case (16-pin) electrical connector out of transmission case.





Installation

1. NOTE: Make sure the tab is in the lock position.

NOTE: Install 2 new O-rings on the transmission case (16-pin) electrical connector.

Install the transmission case (16-pin) electrical connector.

- Lubricate the transmission case (16-pin) electrical connector O-rings with petroleum jelly.





2. Press the transmission case (16-pin) electrical connector through the case until a click is heard.





3. NOTE: Align the slot on the TSS sensor electrical connector with the slot in the (16-pin) case connector.

Install the TSS sensor wire.

1. Install the TSS sensor wire into (16-pin) case connector.

2. Install the TSS sensor wire into the locator.





4. NOTICE: Do not overstretch the retaining spring. Overstretching can damage the spring.

Install the transmission case (16-pin) electrical connector retaining spring.





5. Install the EPC and SSB solenoids.





6. 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).





7. Connect the solenoid electrical connectors.

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

2. Connect the TCC solenoid electrical connector.

3. Connect the EPC solenoid electrical connector.





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

Install the wire harness guide and protector.

- Align the retaining pins to the holes in the solenoid clamps and gently press in the wire harness guide and protector.





9. Connect the vehicle harness to the transmission (16-pin) connector. Make sure the lock is fully engaged.





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