Repair and Diagnosis: Transmission: Clutches: Description

Chevrolet and GMC vehicles incorporate two types of clutches. Both a coil spring and a diaphragm spring type clutch is used. Coil spring type clutch utilizes three release levers to provide pressure plate actuation, and coil springs to provide pressure plate tension. Diaphragm spring type clutch utilizes a single, slotted diaphragm type spring to provide both pressure plate action and tension. All vehicle models use a mechanical type linkage to actuate clutch. Removal and installation procedures and adjustments are the same for both Chevrolet and GMC.
