Remove the transmission mounting bolts and carefully lower the transmission away from the engine.

3. Inspect and Replace Clutch Assembly

Clutch Disc and Pressure Plate:
- Remove the pressure plate bolts and take off the pressure plate and clutch disc.
- Inspect the clutch disc for wear, cracks, or glazing. Replace if necessary.
- Check the pressure plate for warpage or damage. Replace if warped beyond specifications.
Release Bearing:
- Inspect the release bearing for any noise or binding. Replace if defective.
Install New Components:
- Position the new clutch disc using a clutch alignment tool.
- Install the pressure plate and torque the bolts to the manufacturer's specifications (usually between 20-25 ft-lbs).
