The BD Diesel Transmission for 2006-2007 Chevrolet Silverado and GMC Sierra 2500 HD/3500 with LBZ engine offers enhanced durability and performance for heavy-duty applications. Featuring a redesigned oil circuit and a heavy-duty aluminum transmission pan, this transmission increases oil capacity by 3.5 quarts, which improves cooling and reduces internal heat buildup. The pan’s heat-dissipating fins and magnetic drain plug help maintain optimal operating temperature and cleanliness, contributing to prolonged component life. This transmission is engineered to handle up to 300% more power and torque than stock, making it suitable for demanding towing and fleet operations.
Inside, the transmission boasts increased clutch counts across all gear sets—C1 through C5—resulting in smoother shifts and greater torque capacity. With high-energy GPZ friction materials and extra clutch plates, the unit delivers reliable, slip-free engagement under severe load conditions. The inclusion of new pressure control valves, revised oil circuits, and a stronger internal structure ensures consistent performance and long-term reliability. Each unit undergoes dyno testing to verify quality and performance, providing confidence in your upgrade. The package also includes a BD aluminum deep transmission pan, which not only increases oil capacity but also reduces case flex and internal oil leakage, further enhancing durability.
Designed specifically for heavy-duty diesel trucks, this transmission is built to withstand the rigors of towing, hauling, and high-power applications. It features a 36-month or 150,000-mile limited warranty, emphasizing its reliability and quality. Note that use of third-party or OE converters will void the warranty. Proper installation and adherence to break-in procedures are critical to maximizing the lifespan and performance of this transmission, making it an ideal choice for fleet operators and serious towing enthusiasts seeking a robust, high-performance upgrade.
