Socket set
Torque wrench
OBD-II scanner
Clutch alignment tool
Jack and jack stands
Brake cleaner

2. Remove Transmission

Raise the vehicle using a jack and secure it with jack stands.
Remove the driveshaft if applicable (follow specific procedures based on vehicle configuration).
Detach the transmission mount and any wiring harness connected to the transmission.
Unbolt the transmission from the engine using the socket set, ensuring to support the transmission during removal.

3. Inspect and Replace Clutch Components

Remove the old clutch assembly, including the pressure plate, clutch disc, and flywheel.
Inspect the flywheel for wear. If it is damaged or warped, replace it.
Clean the surface of the flywheel and ensure it is free from oil or debris using brake cleaner.
Install the new flywheel if applicable, torquing bolts to manufacturer specifications (typically around 66-85 Nm).
Align the new clutch disc using the clutch alignment tool and install it onto the flywheel.
Install the new pressure plate, ensuring it is securely fastened with bolts torqued to the specified value (usually around 24-30 Nm).

4. Reinstall Transmission

Carefully lift and align the transmission back onto the engine.
Reattach the transmission bolts and torque them to manufacturer specifications.
Reconnect the transmission mount and any wiring harnesses.
Reattach the driveshaft (if removed) and ensure all connections are secure.

5. Final Checks
