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 Work Series?
If you depend on your truck to be there when it counts, the Maximum Work Series Transmission is for you!
Designed to optimize the potential of the Allison transmission even with additional power. Still maintains the smoothness of a stock transmission for everyday use with increased holding capacity when it counts the most. 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.
