Control Valve Body Replacement

^ Tools Required
- J 44257 Main Wiring Harness Connector Remover
- J 44247 Internal Wiring Harness Installer

Removal Procedure





1. Disconnect the external wiring harness from the transmission main connector. Use J 44257 if the connector is not easily accessible.

Caution: Refer to Battery Disconnect Caution in Service Precautions.

2. Remove the oil pan and transmission internal oil filter.





3. Place a 30 mm (1 3/16 inch) 12-point deep socket or box-end (2) over the connector (1).

Important: The transmission main connector is actually one end of the internal harness that protrudes through the transmission case.

4. Push inward on the socket or wrench to release the retainer feet that attach the connector (1) to the transmission case.
5. Remove the wrench. Push inward on the electrical connector to separate it from the transmission case. This allows the internal wiring harness to remain with the control valve assembly when removed.





6. Remove the 2 detent spring bolts (3). Remove the detent spring assembly (2).
7. Disconnect the internal wiring harness from the detent lever/IMS assembly.





8. Remove 10 bolts at locations marked (1) and 4 bolts at locations marked (2). Support the control valve assembly, about 10 pounds, and remove the last bolt marked (1).

Important: As the control valve assembly is removed, be careful not to lose the manual selector valve pin or allow the manual selector valve to slide out of the control valve assembly.






9. Lower the control valve assembly (1) to clear the locating pins (2) in the transmission case.





10. Move the control valve assembly (4) sideways to disengage pin (1) in the manual selector valve (2) from the slot in detent lever (3). Remove the control valve assembly (4).

Installation Procedure





1. Move the control valve assembly (4) into position under the transmission case. Engage the pin (1) in the manual selector valve (2) into the slot in the detent lever (3).





2. Align control valve assembly (1) with the locating pins (2) in the transmission case. Seat the control valve assembly against the transmission case and hold the position.





3. Install one bolt marked (1) to hold the control valve assembly in place.

4. Reinstall the remaining 10 bolts marked (1) and 4 bolts marked (2) that fasten the control valve assembly to the transmission case.
^ Tighten the bolts to 12 Nm (108 inch lbs.).

Notice: Refer to Fastener Notice in Service Precautions.






5. Push the transmission main connector outward through the hole in the transmission case until the retaining feet on the connector are nearing the locked position.





6. Use the J 44247 to complete the seating of the retaining feet that lock the connector (1) into the transmission case.





7. Install the detent spring assembly (2) onto the control valve assembly. Confirm that the roller of the detent spring assembly rests on the detent lever (1).
8. Attach the IMS connector on the internal harness to the IMS.

9. Install 2 detent spring bolts (3).
^ Tighten the bolts to 12 Nm (108 inch lbs.).

Notice: Refer to Fastener Notice in Service Precautions.

10. Install the oil pan and transmission internal oil filter.
11. Connect the external wiring harness to the transmission main connector.
