Clutches operate behind the scenes in many transmissions, including automatics, but the word clutch typically refers to the component that connects and disconnects the engine’s rotating crankshaft to a traditional manual transmission. It disconnects when the driver depresses the clutch pedal, selects a gear using the stick shift and re-engages when the pedal is released. Because the clutch disk is stationary when the transmission is put into First gear or Reverse, it withstands tremendous initial friction when it contacts the engine’s spinning flywheel, moving the car forward. It’s typical for a clutch to require replacement at least once in the car’s lifetime, depending on one’s driving style. Clutch failure can also involve the mechanical or hydraulic connection between the pedal and the transmission.
