14.1.

Rotate the harmonic balancer center bolt clockwise ONLY, in order to align the torque converter bolt holes in the flexplate/flywheel with the access hole in the engine block.

14.2.

To aid in alignment of the torque converter to the flexplate/flywheel. Install all 3 NEW torque converter bolts before fully tightening.

Tighten
Tighten the torque converter bolts to 63 N·m (46 lb ft).




15. Install the torque converter bolt close out cover to the engine block.
16. Install the transmission close out plug.



17. Place NEW O-rings over the transmission fluid cooler pipes.
18. Install the transmission fluid cooler pipes to the transmission. Refer to Transmission Fluid Cooler Pipe Replacement - Rear .
19. Install the transmission fluid cooler lines to the cooler line retainer bracket.
20. Install the front air deflector. Refer to Front Air Deflector Replacement .



21. Install the transmission vent hose to the retaining clips (6) on the transmission mount assembly.
22. Install the wiring harness retainers (4) to the transmission.
23. Connect the transmission wiring harness connector (5) to the transmission by rotating the locking latch clockwise.



24. Install the shift linkage to the transmission. Refer to Transmission Control Replacement .
25. Install the propeller shaft. Refer to Rear Propeller Shaft Replacement .
26. Install the exhaust system. Refer to Exhaust System Replacement .
27. Lower the vehicle.



28. Install the top two transmission mounting bolts (1).

Tighten
Tighten the bolts to 50 N·m (37 lb ft).

29. Check the transmission fluid level and fill if necessary. Refer to Transmission Fluid Check .
30. Adjust the shift control linkage. Refer to Shift Control Linkage Adjustment .

Complete the following procedure after the transmission is installed in the vehicle:

1. With the ignition OFF or disconnected, crank the engine several times. Listen for any unusual noises or evidence that any parts are binding.
2. Start the engine and listen for abnormal conditions.
3. While the engine continues to idle, raise and support the vehicle. Refer to Lifting and Jacking the Vehicle .
4. Inspect for fluid leaks while the engine is idling.
5. Perform a final inspection for the proper fluid level.
6. Lower the vehicle.

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.
7. Reset the TAP values. Refer to Transmission Adaptive Functions .
8. Road test the vehicle.
9. Calibrate the transmission control module (TCM). Refer to Control Module References .
