Tools Required

J 29714-A Servo Cover Depressor

1. Raise the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
2. Support the transmission with a suitable jack.
3. Remove the transmission support. Refer to Transmission Support Replacement in Frame and Underbody.
4. Remove the exhaust manifold pipe. Refer to Exhaust Manifold Pipe Replacement in Engine Exhaust.
5. Place a drain pan under the vehicle.
6. Lower the transmission just enough to gain access to the oil cooler lines.
7. Disconnect the oil cooler lines, if necessary, to gain access to the 2-4 servo. Refer to Transmission Fluid Cooler Hose/Pipe Replacement .
8. Remove the oil pan bolt below and to the left of the 2-4 servo cover.
9. Install the J 29714-A to the oil pan rail.



10. Tighten the bolt on the J 29714-A in order to compress the servo cover.



11. Remove the servo cover retaining ring.
12. Loosen the bolt on the J 29714-A to release tension on the servo cover.



13. Remove the servo cover and O-ring seal. If the cover is hung up on the seal, use a pick (2) to pull and stretch the seal (1) out of the groove. Cut and remove the O-ring seal before removing the cover.



14. Remove the 2-4 servo assembly from the transmission.
15. Inspect the 4th apply piston, the 2-4 servo converter, 2nd apply piston, and the piston inner housing for the following defects:

•

Cracks

•

Scoring

•	Burrs and nicks

1. Install the new seals on the pistons and the servo cover.
2. Lubricate the seals with clean transmission fluid.
3. Install the 2-4 servo assembly into the 2-4 servo bore.
4. Install the servo cover and O-ring seal.
5. Install the J 29714-A .



6. Tighten the bolt on the J 29714-A in order to compress the servo cover.
7. Install the servo cover retaining ring.
8. Remove the J 29714-A from the oil pan flange.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

9. Install the oil pan bolt.

Tighten
Tighten the oil pan bolt to 11 N·m (97 lb in).

10. Connect the oil cooler lines to the transmission, if removed. Refer to Transmission Fluid Cooler Hose/Pipe Replacement .
11. Raise the transmission into place.
12. Remove the drain pan from under the vehicle.
13. Install the exhaust manifold pipe. Refer to Exhaust Manifold Pipe Replacement in Engine Exhaust.
14. Install the transmission support. Refer to Transmission Support Replacement in Frame and Underbody.
15. Remove the transmission jack.
16. Lower the vehicle.
17. Fill the transmission to the proper level with DEXRON® VI transmission fluid. Refer to Transmission Fluid Check .

Important: It is recommended that transmission adaptive pressure (TAP) information be reset.

Resetting the TAP values using a scan tool will erase all learned values in all cells. As a result, The ECM, PCM or TCM will need to relearn TAP values. Transmission performance may be affected as new TAP values are learned.
18. Reset the TAP values. Refer to Transmission Adaptive Functions .
