A mechanic with the proper tools typically takes four to eight hours to replace a clutch. Features that impact the time are whether the vehicle has front or rear wheel drive, whether it has a manual or automatic transmission, and whether it is a specialty vehicle.
A manual transmission clutches typically has more parts, but is often less complicated to replace than a clutch in a vehicle with an automatic transmission. To change the clutch on a front wheel drive vehicle, the mechanic may have to remove the entire engine and transmission assembly, uncouple them, remove and replace the clutch, and then reassemble the engine and transmission before reinstalling. A specialty vehicle may include valves, extra gears or dual clutches, and working on it may require special tools.
