Heavy Duty / Performance Transmissions

We have been remanufacturing transmissions for 35 years. We only build a few different heavy duty/performance transmissions so we can dyno test each transmission before shipping them out. This sets us apart from the rest of the large transmission remanufacturers. They do random checks or no checks at all. We provide the highest quality remanufactured transmissions and customer service to every one we deal with. We remanufacture your heavy duty/performance transmissions to your specs and dyno test it before it’s shipped out. Heck, you can come and watch us dyno test it if you like.
