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.

5. Install the forward band servo cover bolts.

Tighten
Tighten the forward band servo cover bolts to 12 N·m (106 lb in).

6. Remove the drain pan from under the forward servo cover.

Important: Ensure that the power steering cooler line does not become trapped or damaged during this step.

7. Use the utility stand in order to raise the frame rear.
8. Install the NEW frame bolts.
9. Install the powertrain mounts to the frame.
10. Install the transaxle mount nuts. Refer to Transmission Mount Replacement .
11. Install the engine mount nuts. Refer to Engine Mount Replacement in Engine Mechanical.
12. Install the power steering gear to the frame. Refer to Steering Gear Replacement in Power Steering System.
13. Install the power steering gear heat shield. Refer to Steering Gear Heat Shield Replacement in Power Steering System.
14. Install the stabilizer shaft. Refer to Stabilizer Shaft Replacement in Front Suspension.
15. Lower the vehicle.
16. Remove the engine support fixture. Refer to Engine Support Fixture in Engine Mechanical.

Important: It is recommended that the 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 the TAP values. Transmission performance may be affected as new TAP values are learned.
17. Reset the TAP values. Refer to Adapt Function .
