In-House Dyno

Every heavy duty unit is Dyno tested in-house. We test manual as well as Allison automatics. Each unit is tested for leaks, air operation, and load to ensure a quality product.


We have over 30 years of collective experience specifically rebuilding heavy duty transmissions, differentials, PTOs, and transfer cases. 

Process of Rebuilding

We specialize in rebuilding all makes and models of heavy duty manual transmissions, Allison automatics, and differentials. PTO and transfer case rebuilding is also available. We use genuine OEM gears, seals, synchronizers, air valves, gaskets, as well as high quality industry standard aftermarket parts.
