The most common major transmission repair is a clutch replacement. Three parts are usually replaced during this repair, the pressure plate, clutch disc and throw out bearing. The pressure plate costs between $40 for a four cylinder economy car and $150 for a high performance eight cylinder. Clutch discs cost between $30 and $200, again with the high number being for a high performance vehicle. Throw out bearings cost between $20 and $50, depending on the application.
