Transmission Repair

Fixing your transmission problem right starts with diagnosing your problem correctly. That’s why at American Transmissions and 5 Star Auto Repair we perform our exclusive Multi-Point Transmission Diagnostics Test on every vehicle before we do any transmission repair or service.

These diagnostics includes a computer scan of your transmission computer, an internal pressure test of your internal hydraulic system, checking all external components that make your transmission perform properly. We will perform a road test to experience your issue first hand and to evaluate the gear range, upshift and downshift ease and quality as well as check for noises and vibrations.

Through these extensive checks your American Transmissions technician will diagnose your transmission problem correctly to then recommend the right repair for your transmission issue.

Services Provided:
Automatic Transmission Rebuilds
Standard Transmission Rebuilds
Differential Rebuilds
Driveshaft Replacement


Our Advanced Computer Diagnostics are the next level of diagnostics that ensure American Transmissions technicians will only fix what is needed. Many transmission problems start in the computer system – where your transmission receives the wrong signals. The American Transmissions diagnostic service is performed to determine if an electronic component is impairing your transmissions shifting or overall performance. Then, we will determine the fix after the diagnosis is performed.

This includes:
• Using a computer system scanner to retrieve trouble codes and their cause.
• Reviewing the computer system data against our technical database – the most extensive transmission diagnostic source available.
• Connecting the American Transmissions KwiktestTM PlusBox to see if the issue is internal or external to the transmission.

The technician was very informative and patient with us. This gentleman alone made my experience one that I won't forget, and I would go as far as to say it was enjoyable. Thanks!

American Transmission 5 stars

We took our 2012 manual transmission vehicle in because 3rd gear was popping out. Mike and his team were very diligent in finding and correcting the elusive problem. Mile's professionalism and courtesy make the frustrating situation more bearable. We would recommend this business.
