Experienced Manual Transmission — General Service specialists since 1987. Free computer diagnostic, lifetime warranty on rebuilds.
Manual transmissions use a driver-operated clutch and gear selector to manually choose gear ratios through a fixed gear set. They're simpler than automatics but require clutch, synchro, and bearing service over time. We rebuild manual transmissions from all manufacturers — import sport compacts to heavy-duty domestic trucks.
