Merchant Automotive has a long history of building transmissions for customers from all over the country who depend on their truck for many types of applications. The components in the Maximum transmission kits were selected specifically based on our experience working exclusively on the GM Duramax trucks with an Allison transmission.
Why the Pro Series?
Designed to optimize the potential of the Allison transmission even with additional power. We take the proven reliability of the Work Series and increase capacity even more with additional clutch apply area, heavy duty friction material, and additional hydraulic pressure to ensure Maximum holding capacity.
For use with engines modified above stock, or aftermarket components (proper tuning and gearing required). Includes everything you need to not only upgrade the transmission, but rebuild it as well. A truly complete kit to get you back on the road worry free.
