Control Valve Body Replacement

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

Removal Procedure

Caution: Refer to Battery Disconnect Caution in Service Precautions.





1. Disconnect the external wiring harness from the main transmission connector. Use the J 44257, if connector is not easily accessible.
2. Remove the oil pan and suction filter.





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

3. Place a 30 mm or 1 3/16 inch 12-point deep socket or box-end (2) over the connector (1).
4. Push inward on the socket or wrench to release the retainer "feet" that attach the connector (1) to the main housing.
5. Remove the wrench. Push inward on the electrical connector to separate it from the main housing. This allows the internal wiring harness to remain with the control valve assembly as it is removed.





6. Remove the two detent spring bolts (3). Remove the detent spring assembly (2).





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

7. Remove 14 bolts at locations marked (1). Support the control valve assembly (about 10 pounds) and remove the last bolt marked (1).





8. Lower the control valve assembly (1) to clear the dowel pins (2) in the main housing.





9. 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 main housing. Engage the pin (1) in the manual selector valve (2) into the slot in the detent lever (3).





2. Align the control valve assembly (1) with the dowel pins (2) in the main housing. Seat the control valve assembly against the main housing and hold it in position.





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

Notice: Refer to Fastener Notice in Service Precautions.

4. Reinstall the remaining 14 bolts marked (1) that fasten the control valve assembly to the main housing.
^ Tighten the bolts to 12 Nm (108 inch lbs.).





5. Push the main transmission connector (2) outward through the hole (1) in the main housing 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 main housing.





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. Install two detent spring bolts (3).
^ Tighten the bolts to 12 Nm (108 inch lbs.).
9. Install the oil pan and suction filter.
10. Connect the external wiring harness to the main transmission connector.
