1. Preparation

Tools Required: Socket set, torque wrench, brake cleaner, clutch alignment tool, jack and jack stands.
Ensure the vehicle is parked on a level surface, engage the parking brake, and disconnect the battery.

2. Remove Transmission

Lift the vehicle using a jack and secure it on jack stands.
Remove the underbody shield if equipped.
Disconnect the driveshaft if necessary, ensuring to mark the orientation for reinstallation.
Detach the shift linkage and any electrical connectors associated with the transmission.
Support the transmission with a transmission jack and unbolt it from the engine block.
Carefully lower the transmission and remove it from the vehicle.

3. Inspect and Replace Components

Remove the clutch assembly, including the disc, pressure plate, and flywheel.
Inspect the flywheel for any damage or warping; machine or replace if necessary.
Check the release bearing for signs of wear; replace if necessary.
Install a new clutch disc and pressure plate, ensuring proper alignment using a clutch alignment tool.
Torque the pressure plate bolts to the manufacturer’s specifications (typically around 18-25 ft-lbs, verify for your specific model).

4. Reassemble and Install Transmission

Reinstall the flywheel if it was removed, torquing the bolts to specifications (typically around 70-80 ft-lbs, verify for your specific model).
