Each shop defines overhaul differently. Here at A&A, a transmission overhaul consists of replacing what we call soft parts. Soft parts include all the clutches, seals, gaskets, any bands, bushings, washers, the filter, and the torque converter. While we are in there, we check and replace the internal electronics, as well as make appropriate computer updates. We also make improvements to your transmission. Transmissions nowadays have a big problem with the valve bodies wearing out. We have tools and equipment to bore those out, and put oversized valves in. This is critical to the overhaul, because if we don’t fix those things the transmission will wear out prematurely.
