Whether you drive a Ford, Chevy, or Ram diesel pickup, it’s especially important that you always seek high-quality repair and maintenance from qualified professionals. At Flagstaff Transmission Specialists in Flagstaff, AZ, we specialize in diesel vehicles and the ins and outs of diesel servicing. There are plenty of shops out there that can replace a part or perform a job, but it’s important that the technicians doing the work know what they’re doing, why they’re doing it, and are doing it right.

Our qualified diesel technicians know your Powerstroke, Cummins, or Duramax through and through. We know what to look for, and make decisions based on cost efficiency, reliability, performance, and any other variable at play. We always use high-quality parts and perform high-quality repairs - meaning your truck will be in the shop less often. We do everything possible to ensure reliability, prevention of further complications and repeat repairs. With the knowledge, wisdom, and equipment our technicians possess, it simply doesn’t make sense to risk it anywhere else.
