Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical shorts.
Lift the vehicle using a hydraulic jack and secure with jack stands.

2. Remove Transmission Components

Drain Transmission Fluid:
- Place a drain pan under the transmission pan.
- Remove the transmission pan bolts and carefully lower the pan.
Remove Torque Converter Access Cover:
- Unbolt and remove the access cover to the torque converter (if applicable).
Disconnect Transmission:
- Remove the driveshaft or axles (depending on configuration).
- Unbolt the transmission from the engine block.
- Disconnect all wiring harnesses, shift linkage, and cooler lines.

3. Remove Slipping Torque Converter

Unbolt Torque Converter:
- Rotate the engine using a socket on the crankshaft pulley to access all torque converter bolts.
- Remove the bolts securing the torque converter to the flexplate.
Pull the Torque Converter:
- Carefully pull the torque converter off the transmission input shaft.
- Ensure no damage occurs to the transmission seal.

4. Install New Torque Converter

Lubrication:
- Apply a thin coat of transmission fluid to the input shaft and the new torque converter’s seal.
Install Torque Converter:
- Align the torque converter with the transmission input shaft.
- Push the torque converter onto the shaft until it seats properly.
Bolt Torque Converter:
- Reinstall the torque converter bolts to the flexplate, tightening to the manufacturer’s specified torque (typically around 40-50 ft-lbs).

5. Reassemble Transmission Components

Reattach Transmission:
- Lift the transmission back into place and secure it to the engine block.
Reconnect Components:
- Reattach the driveshaft or axles.
- Reconnect all wiring harnesses, shift linkage, and cooler lines.
Reinstall Access Cover and Transmission Pan:
- Replace the torque converter access cover.
- Reinstall the transmission pan with a new gasket, tightening bolts to the specified torque.

6. Fill Transmission Fluid

Fill the transmission with the appropriate type and amount of fluid as specified in the owner’s manual.
