Merchant Automotive MAximum Allison Transmission Kit - Pro Series | 2001 - 2004
Due to daily fluctuating stock levels, please call (616) 772-9551 for time sensitive orders.
Our signature line or Maximum Transmissions builds off the proven reliability of the Allison 1000 used in 2001 to Early 2004 GM LB7 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.
