Step-by-Step Guide
1. Prepare the Vehicle
- Raise the vehicle using a floor jack and secure it with jack stands. Ensure the vehicle is stable and supported.
- Locate the transmission fluid pan and remove the drain plug to drain the fluid into a drain pan.

2. Disconnect the Transmission
- Disconnect the transmission cooler lines by loosening the clamps and removing the hoses. Be prepared for fluid leakage.
- Disconnect the electrical connectors from the transmission, including the shift cable and any sensors.
- Remove the bolts securing the transmission to the engine and bell housing. You might need a breaker bar for stubborn bolts.
3. Support the Transmission
