Replace and tighten the fill plug to the specified torque (consult vehicle manual).

3. Inspect and Replace Clutch Components

Tools Required: Socket set, torque wrench, clutch alignment tool
Remove the transmission from the engine by detaching the necessary bolts and supports.
Inspect the clutch disc, pressure plate, and flywheel for wear.
