Clutch

The clutch is a mechanical device that temporarily disconnects the engine from the manual transmission, which allows for a smooth transition from one gear to another.

Symptoms of Wear or Failure

  • Difficulty shifting gears
  • Clutch may slip, shudder, or be difficult to depress
  • Engine will "rev," but speed will not increase/vehicle will not move

Related Repair Advice

  • Engine oil or transmission fluid leaks can damage a clutch. When replacing a clutch, any leaks should be diagnosed and repaired to avoid recurring problems. As a preventive measure, it's not uncommon for a shop to recommend replacement of the rear main seal and/or the transmission input shaft seal even when not leaking; it's a good insurance policy against expensive future repairs
  • If it is defective, the transmission input shaft should be inspected and replaced along with the clutch
  • Most shops recommend the flywheel be resurfaced when the clutch is replaced (where applicable).
  • On some vehicles, the clutch slave cylinder is located in with the clutch assembly. To avoid having to remove the transmission before the next clutch job, we recommend the slave cylinder is replaced at the same time as the clutch.
  • Incorrect linkage/cable adjustment or "riding" the clutch (resting one's foot on the clutch pedal, not allowing the clutch to release completely) can cause premature clutch failure
