Product Information

Our signature line or MAximum Transmissions builds off the proven reliability of the Allison 1000 used in late 2004 to 2005 GM LB7 Duramax diesel trucks, but vastly improves the performance by incorporating several key upgrades that will unleash your Allisons true potential.

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, it still maintains the smoothness of a stock transmission. If you’re looking for everyday use with increased holding capacity when it counts the most, look no further than the MAximum Work Series Transmission.
