BD Diesel Valve Body - 2006-2007 Duramax LBZ Allison 1000

If you're looking to get the most out of your Allison 1000 transmission, especially when towing or pushing your Duramax LBZ engine, a modified valve body can make a significant difference. This unit from BD Diesel is specifically tuned and tested to optimize performance for these demanding applications. It's designed to work with a range of GM trucks, including models like the 2006-2010 Chevrolet Silverado 2500 HD and GMC Sierra 2500 HD.

BD Diesel takes their exchange valve bodies and modifies them to provide improved shift quality and increased clutch holding capacity. This means less wear on your transmission components and a more solid feel when you're under load. They achieve this through several updates, including new trim valves that increase main line pressure and clutch apply pressures, along with proprietary governor piston dimensions. The hand-lapped surfaces are a notable detail, as they help prevent internal leaks, contributing to reduced friction and extended transmission life. Larger oil ports are also incorporated to help manage fluid flow more effectively.

This valve body is a well-built component designed to handle the stresses of performance diesel use. It comes with the necessary hardware to complete the installation, and BD Diesel includes a UPS shipping label to return your old core for free within the USA. This is a solid option if you're looking for a more robust and responsive transmission performance from your Duramax.
