Remove Components: Disconnect any components obstructing the transmission removal, including:
- Exhaust system (if necessary)
- Shift linkage
- Electrical connections
- Clutch master cylinder (disconnect lines and support it out of the way)
Unbolt Transmission: Remove all bolts securing the transmission to the engine. Use a torque wrench to ensure proper reinstallation.
Separate Transmission: Carefully slide the transmission away from the engine and lower it to the ground.

Remove Old Clutch: Unbolt the pressure plate from the flywheel, and remove the clutch disc.
Inspect Flywheel: Check for wear, hotspots, or damage. Resurface or replace if necessary.
Install New Clutch:
- Place the new clutch disc on the flywheel.
- Use a clutch alignment tool to ensure proper positioning.
- Install the pressure plate and tighten bolts in a crisscross pattern to the manufacturer's torque specifications.

4. Reinstall Transmission

Align and Lift: Align the transmission with the engine, lifting it back into place.
Bolt Transmission: Secure with bolts and tighten to the specified torque.
Reconnect Components: Reinstall all components removed earlier, ensuring all electrical connections and linkages are secure.
