The labor involved in repairing an automobile’s transmission is a big cost factor, and in some cases may account for more than half the total cost. Manage your expectations regarding the turnaround time for your mechanic to complete repairs. It can take extra time when you’re waiting on parts to get delivered, especially from overseas. Transmission parts cost more for CVT transmissions, and also for luxury brands, commercial vehicles, heavy-duty trucks, and import transmissions. Part availability can be cumbersome; some parts take longer to ship.
