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 (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 2 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 or allow the manual selector valve to slide out of the control valve assembly.

7. Remove 11 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).





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 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 10 bolts marked (1) and 4 bolts marked (2) that fasten the control valve assembly to the main housing.
^ Tighten the bolts to 12 Nm (108 lb in).





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).

Notice: Refer to Fastener Notice in Service Precautions.

8. Install 2 detent spring bolts (3).
^ Tighten the bolts to 12 Nm (108 lb in).
