•	The oxygen sensors

•	The wiring harnesses

•	The cooler pipes

27. Carefully lower the transmission from the vehicle.
28. Flush the transmission oil cooler. Refer to Transmission Fluid Cooler Flushing and Flow Test .
29. If the transmission is being replaced and it is a rear wheel drive vehicle, transfer the drive flange from the old unit to the new unit. Refer to Drive Flange and Seal Replacement .

Important: Ensure clearance is maintained between the transmission and the following:

•	The catalytic converters

•	The oxygen sensors

•	The wiring harnesses

•	The cooler pipes

1. Using the transmission jack, carefully raise the transmission to meet the engine.



2. Align the transmission with the engine dowels (1).

Notice: Refer to Fastener Notice in the Preface section.

3. Install the lower 8 transmission mounting bolts.

Tighten

•	Tighten the M10 x 1.5 bolts to 50 N·m (37 lb ft).

•	Tighten the M12 x 1.75 bolts to 75 N·m (55 lb ft).

4. Remove the support stand from under the engine oil pan.




Important: Be careful to NOT allow the front differential drive pinion flange, if equipped, to come in contract with power steering rack while lowering the transmission.

5. Using the transmission jack. Lower the engine and transmission assembly only enough to gain access to the upper transmission bolt locations.
6. Install the upper transmission mounting bolts.

Tighten

•	Tighten the M10 x 1.5 bolts to 50 N·m (37 lb ft).

•	Tighten the M12 x 1.75 bolts to 75 N·m (55 lb ft).

7. Position the engine wiring harness to the original location.
8. Install the transfer case if equipped. Refer to Transfer Case Assembly Replacement in Transfer Case - BW 4476.
9. Align the torque converter to flexplate/flywheel orientation marks made during the removal procedure.

Important: Torque converter bolts are self locking and must be replaced with NEW torque converter bolts every time the bolts are removed.

10. Complete the following steps for all 3 torque converter bolts:

10.1.

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

10.2.

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).




11. Install the starter motor. Refer to Starter Motor Replacement in Engine Electrical.



12. Install the front air deflector. Refer to Front Air Deflector Replacement in Body Front End.



13. Place NEW O-rings over the transmission fluid cooler pipes.
14. Install the transmission fluid cooler pipes to the transmission. Refer to Transmission Fluid Cooler Pipe Replacement - Rear .
15. Clip the transmission fluid cooler lines into the plastic cooler line retainer bracket.



16. Install the front differential heat shield and bracket, if equipped. Refer to Shield Replacement in Front Drive Axle.

25. Adjust the shift control linkage. Refer to Shift Control Linkage Adjustment .
26. Lower the vehicle.

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 in General Information.
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.
