BD Diesel Valve Body - 2001-2004 Duramax LB7 Allison 1000

If you're towing heavy loads or pushing your Duramax LB7 beyond stock, you know how hard your Allison 1000 transmission can work. This BD Diesel valve body is modified to help your transmission handle more power and shift more smoothly, especially under load. It's designed to give your transmission a tougher feel and extend its life.

BD Diesel takes these valve bodies and tunes them specifically for performance and towing. They've updated the valve design with larger oil ports for better flow and hand-lapped surfaces to prevent internal leaks. New trim valves are installed to increase clutch apply pressures, which means your transmission can hold more torque without slipping. This not only improves shift quality but also reduces friction and wear on your transmission's internal components, leading to a longer transmission life.

This kit includes the modified valve body and necessary hardware. BD Diesel also includes a UPS shipping label to return your original core for free within the USA, making the exchange process straightforward. This is a solid option if you're looking to get more out of your Allison 1000 transmission.
