Removal and Replacement
Transmission - Four Wheel Drive (4WD)
Installation
All vehicles
NOTE: Prior to installing a new transmission or an overhauled transmission with a new main control, record the solenoid strategy identification tag. If a new main control was installed, install the replacement solenoid body tag over the original identification tag. For additional information, refer to Solenoid Body Strategy Solenoid Body Strategy.
1. NOTICE: Prior to installation of the transmission, lubricate the torque converter pilot hub with multi-purpose grease or damage to the torque converter or engine crankshaft can occur.
Lubricate the torque converter pilot hub with multi-purpose grease.
2. Align the torque converter stud and flexplate hole near the paint marks at the 12 o'clock position.
3. Install the Torque Converter Retainer.
4. WARNING: Always secure transmission, transfer case, and axle assemblies to their service jack. Avoid obstructions while lowering and raising the jack. Improperly secured assemblies or contact with obstructions may cause the assembly to fall off the jack, which could result in serious personal injury.
NOTICE: The torque converter housing is piloted into position by dowels in the rear of the engine block. The torque converter must rest squarely against the flexplate. This indicates the torque converter pilot is not binding in the engine crankshaft.
NOTE: Make sure the transmission jack contacts the outer ribs of the transmission fluid pan.
NOTE: If transmission was disassembled, follow the add transmission fluid to the transmission steps. If transmission is being replaced, remove the transmission fluid fill plug and verify transmission is filled with transmission fluid.

5. NOTICE: The torque converter housing is piloted into position by dowels in the rear of the engine block. The torque converter must rest squarely against the flexplate. This indicates the torque converter pilot is not binding in the engine crankshaft.
Position and secure the transmission on the high-lift transmission jack. Raise and position the transmission into the vehicle behind the engine.
6. Remove the Torque Converter Retainer.
7. NOTICE: Make sure the transmission wiring harness is not between the engine block and transmission prior to moving the transmission toward the engine or damage can occur.
NOTE: Make sure the torque converter is fully seated in the transmission before aligning the transmission to the engine.
With the transmission in a horizontal position, move it toward the engine and position it on the dowel pins.

All vehicles
17. Install the starter motor.
18. Reposition the transmission fluid cooler tubes and bracket and install the transmission fluid cooler tube bracket nut.
- Tighten to 12 Nm (106 lb-in).
19. NOTE: Inspect the case to make sure the old transmission fluid cooler tube O-rings are not stuck in the case.
Install new transmission fluid cooler tube O-rings on the transmission fluid cooler tubes.
20. NOTICE: Install a new transmission fluid cooler tube bracket bolt.
Install the transmission fluid cooler tubes and a new transmission fluid cooler tube bracket bolt.
- Tighten to 30 Nm (22 lb-ft).
21. NOTE: The column shift is shown, the floor shift similar.
Install the selector lever cable bracket and selector lever cable bracket bolts.
- Tighten to 25 Nm (18 lb-ft).
Vehicles equipped with a 5.0L or 6.2L engine
22. Align the transmission fluid cooler tube bracket and install the remaining transmission-to-engine bolt.
- Tighten to 48 Nm (35 lb-ft).
All vehicles
23. Install the fuel line bracket and the fuel line bracket bolt.
- Tighten to 25 Nm (18 lb-ft).
24. Position a jack stand under the transmission, and remove the high-lift transmission jack.
25. NOTE: Do not reuse the old transfer case-to-transmission bolts.
If the transfer case was removed from the transmission during removal, install the transfer case using a high-lift transmission jack. Install 9 new transfer case-to-transmission bolts.
- Tighten the bolts evenly in a cross pattern to 17 Nm (150 lb-in).
26. Connect the vent hose to the transfer case.

29. Connect the cable end to the shift lever.
30. Install the front and rear driveshafts.
31. Install the exhaust Y-pipe.
32. Connect the battery ground cable.
33. Adjust the selector lever cable and install the selector lever cable end on the manual control lever. Verify the selector lever cable is correctly adjusted.
34. After completing the repairs, use the scan tool to perform the Misfire Monitor Neutral Profile Correction procedure, following the on-screen instructions.
35. If a new transmission or a new main control was installed, the solenoid body strategy must be updated. For additional information, refer to Solenoid Body Strategy Solenoid Body Strategy.
36. If the transmission was overhauled, the adaptive drive cycle must be updated. For additional information, refer to Shift Point Road Test Shift Point Road Test.
37. While driving the vehicle, use the scan tool to verify that the Transmission Fluid Temperature (TFT) has reached a temperature of 91°C (195°F). This will circulate the transmission fluid through the torque converter and the transmission fluid cooling system, eliminating any trapped air in the transmission fluid cooling system.
- With the engine idling (600-750 rpm) in PARK, verify that the TFT (Transmission Fluid Temperature) is between 91°C-102°C (195°F-215°F).
38. Remove the transmission fluid fill plug transmission fluid level indicator assembly located on the passenger side front portion of the transmission case.
39. Separate the transmission fluid level indicator from the transmission fluid fill plug.
40. Wipe the transmission fluid level indicator clean. Reinstall the transmission fluid level indicator only back into the transmission fluid fill plug hole to check the transmission fluid level. Repeat this until a consistent reading is established.
41. NOTE: If the transmission fluid is not at the correct level, follow the steps for Adding Additional Transmission Fluid or Removing Transmission Fluid. For additional information, refer to Transmission Fluid Drain and Refill Transmission Fluid Drain and Refill.
Install the transmission fluid fill plug.
- Tighten to 35 Nm (26 lb-ft).
