Product Description
The BD DIESEL 1030471 Allison Exchange Valve Body is a high-quality transmission valve body designed for Chevrolet / GMC Silverado and Sierra 2500/3500 trucks equipped with the 6.6L Duramax LLY engine and Allison 1000 transmission (2004–2006). This unit is an exchange valve body that has been modified, tuned, and tested to deliver improved shift quality, increased clutch holding capacity, reduced internal wear, and enhanced overall transmission performance in both towing and daily driving applications.
BD Diesel’s exchange valve bodies undergo meticulous rework including revised valve design, new trim valves to raise clutch apply pressure, and hand-lapped surfaces to prevent internal leakage. The enhanced fluid control and durable construction help extend transmission life while improving responsiveness under load. This valve body replaces the stock component and restores reliable performance in demanding duty cycles.
