Dyno-Tested
Every transmission has been run on a state of the art Dyno. A Dyno simulates the conditions encountered by a transmission during every day and extreme use. This ensures that when your part arrives, it will have been rigorously tested for noises, leaks, vibrations and performance. Any part that does not meet our strict guidelines will be completely disassembled and gone through until our quality requirements have been restored.

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

Upgrades
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.

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

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

Inspection
The final process before shipment is a complete inspection of the entire unit. During our inspection process, even the smallest of inconsistencies are addressed.
