Your transmission carries the whole load, and problems like slipping, hard shifts, or grinding rarely fix themselves. We diagnose and repair heavy-duty transmissions, including manual, automatic, and automated manual units. From fluid service and clutch work to electronic shift faults and internal repairs, we find the cause before we replace anything. With our OEM-level diagnostic tools we can also read transmission control module data and fault codes, so you’re not paying for parts you don’t need. We offer service in our shop or on-site with our mobile mechanic service.
