Our professional staff of technicians and 16 heavy duty service lifts enable us to get you and your car up and running as quickly as possible. However, because it is impossible to judge the exact nature of the problem from a phone call, we can only provide transmission repair recommendations and price estimates after carefully examining your vehicle. We welcome your questions and will be delighted to make an accurate diagnosis.
