Every transmission has been run on a state of the art Dyno. A Dyno simulates the conditions encountered by a transmission during every day use. This ensures that when your part arrives it will have been rigorously tested for noises, leaks, vibrations and performance.

O.E.M. stands for Original Equipment Manufacturer. Our parts meet or exceed the guidelines set forth by the manufacturer.

Some transmissions have inherent factory flaws causing them to chronically break down. Through years of experience we have developed several procedures to help fix these problems.

Every remanufactured transmission has been built and inspected by a certified technician. Our technicians have an average experience of 10 years.

New Parts
All wearable parts are replaced, this includes: seals, bearings, synchronizers, O-rings, bushings, bands, gaskets, and much more.
