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.

The Highest Quality, at an affordable price!, October 6, 2017 By DYLAN (Rye, NH)(Verified)
Even the packaging shows the care and thought that went into engineering this kit. Installation was straight forward and smooth. Just to give an idea of the detail level, a roll of 1/4" wide Teflon tape is supplied to reseal the PTO cover bolts; just as they came from the factory.
When I order from Merchant Automotive, I expect the highest quality product and this kit is no exception. The research and engineering that went into developing this kit manifests itself by producing the cleanest, most crisp shifting Allison one could ever experience.
