Transmission Removal

Transmission





Special Tool(s)

Removal
All vehicles
1. With the vehicle in NEUTRAL position it on a hoist.

2. NOTE: When the battery has been disconnected and reconnected, some abnormal drive symptoms can occur while the vehicle relearns its adaptive strategy. The customer needs to be notified that they may experience slightly different upshifts (either soft or firm) and that this is a temporary condition that will eventually return to normal operating condition.

Disconnect the battery ground cable.

4x4 vehicles
3. Remove the transfer case assembly.

4x2 vehicles
4. Remove the rear driveshaft.

All vehicles
5. If transmission disassembly is required, drain the transmission fluid.

Vehicles equipped with a fluid pan drain plug





6. Remove the drain plug and allow the fluid to drain.





7. Install the drain plug.

Vehicles not equipped with a fluid pan drain plug





8. NOTE: Do not discard the gasket unless damaged. This is a reusable gasket.

Remove the transmission fluid pan and gasket.





9. NOTE: The transmission pan gasket is reusable unless damaged.

NOTE: Apply a light coat of petroleum jelly to hold the gasket to the fluid pan.

Position the gasket onto the cleaned fluid pan. Make sure the magnet is positioned over the dimple in the fluid pan.





10. CAUTION: Mixing the 4x2 and the 4x4 style transmission fluid filters and transmission pan assembly components can cause transmission damage.

Install the correct pan with gasket for this application. Alternately tighten the bolts.

11. CAUTION: Make sure securing straps or the transmission jack adapter do not touch the Cooler Bypass Valve (CBV). Do not use the CBV as a handle. Damage to the CBV can cause a leak.

Install a suitable transmission Jack and support the transmission.

21. Disconnect the shift cable from the transmission.
1 Disconnect the shift cable from the manual lever.
2 Remove the shift cable bracket from the transmission and position aside.





22. Disconnect the digital Transmission Range (TR) sensor connector and the wire loom from the shift cable bracket.





23. Disconnect the solenoid body connector.





24. Disconnect the Turbine Shaft Speed (TSS) sensor and the Output Shaft Speed (OSS) sensor.
25. Remove the wiring harness from the transmission and position aside.





26. Remove the flexplate inspection cover.
1 Remove the bolts.
2 Remove the inspection plate.
27. Remove the starter motor.

29. Remove and discard the torque converter-to-flexplate nuts.
^ 5.4L engine has four torque converter-to-flexplate nuts.
^ 6.8L engine has six torque converter-to-flexplate nuts.





30. Position a suitable drain pan and disconnect the transmission fluid cooler tubes from the cooler bypass valve.





31. Remove the transmission.
1 Remove the seven transmission-to-engine mounting bolts.
2 Gently rock the transmission side-to-side to disengage it from the locator dowels.
3 Move the transmission and the transmission jack rearward to clear the engine flexplate.





32. WARNING: The torque converter is heavy and can result in injury if it falls out of the transmission. Secure the torque converter in the transmission. If the torque converter is dropped, a new one must be installed.

Using the special tool, hold the torque converter in place.





33. CAUTION: Use care while removing the transmission to avoid obstructions.

CAUTION: Do not use the cooler bypass valve as a handle. Damage to the cooler bypass valve assembly can occur or damage to the case can result.

CAUTION: If a safety strap is being used to hold the transmission to the high-lift transmission jack, place the strap behind the Cooler Bypass Valve (CBV) to prevent damage to the cooler bypass valve.

Lower the transmission out of the vehicle.
34. If the transmission is being overhauled or if installing a new or remanufactured transmission, carry out the transmission fluid cooler backflushing and cleaning.
