Diagnostics & Troubleshooting

This is the most important part of transmission repair, without proper direction you are spending time and money unwisely. Electrical components and even the battery and charging systems can make for transmission drivability problems.

We have developed a shop dedicated to the diagnostics of transmissions and transfer cases, both mechanical and electrical. We are recognized as one of the leaders in professional and honest evaluations of problems.

The mechanical type problems including noises and drivability issues can sometimes be diagnosed by the tried and true method of road checks the electronic / computer age has brought in a whole new era of diagnostics. Vehicles can have failures in either area or both. It is imperative the diagnosis procedure is completed both prior to and after repairs are made. Computer controlled transmissions have created a whole new agenda in failure diagnosis. It is also imperative that you be able to retrieve trouble codes and have access to the proceedure and test equipment to pinpoint the problem
