Merchant Automotive 10740 MAximum Work Series Allison 1000 Transmission 01-02 6.6L GM Duramax LB7
It's true, the Allison 1000 transmission originally set the bar pretty high upon its initial unveiling on the first Duramax-equipped Chevy back in 2001. Many looked to this transmission as being the cure for any future transmission issues. And to some degree, the Allisons have proven themselves, but as with all things, time, hard work, and horsepower will cause them to fatigue and fail. Fortunately, the professionals at Merchant Automotive know the ins and outs of properly building an Allison to deliver the reliability you need from your truck.
Merchant Automotive has a long history of building transmissions for customers from all over the country who depend on their trucks for many types of applications. The components in the Maximum Transmissions were selected specifically based on our experience working exclusively on the GM Duramax trucks with an Allison transmission.
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, this transmission still maintains the smoothness of the stock unit for everyday use, but with increased holding capacity when it counts the most.
