Product Information

Our signature line or Maximum Transmissions builds off the proven reliability of the Allison 1000 used in 2006 to 2010 GM LBZ and LMM Duramax diesel trucks, but vastly improves the performance by incorporating several key upgrades that will unleash your Allisons true potential. 

The Pro Series improves the performance of your Duramax with even greater holding capacity with an additional clutch apply area, heavy duty friction material, and additional hydraulic pressure. If your engine is modified above stock, or aftermarket components (proper tuning and gearing required), then the Maximum Pro Series is for you.
