BD Diesel Shift Kit – Chevrolet Allison 1000 2006-2008 6spd – Part # 1604721

The BD Diesel shift kit designed for the Chevrolet Allison 1000 transmission enhances shift pressures and improves overall shifting performance. This performance upgrade includes clutch control valve assemblies and springs that optimize the transmission’s hydraulic functions, resulting in shorter, crisper, and smoother upshifts and kickdowns. The kit is engineered to address common issues such as going to neutral under load, sticking in one gear, or failure to move after extended parking, providing a reliable solution for heavy-duty applications.
This shift kit features our exclusive Smart Trim and Clutch Control valve assemblies, which increase durability and shift consistency under demanding conditions. It is recommended for experienced technicians to install this kit to ensure proper calibration and performance. The modifications help the transmission handle up to 500 street horsepower, making it suitable for trucks with increased power levels or towing capacity. The kit also includes components to modify the C2 clutch piston, increasing capacity and durability where the weakest link in early 5-speed Allison transmissions typically occurs.
Designed for vehicle applications including 2006-2008 Chevrolet Silverado 2500 HD and Silverado 2500 HD Classic models, this kit improves shift quality and durability without the need for additional modifications. Proper installation and maintenance are essential to maximize the performance and lifespan of your transmission, especially under heavy loads or high-performance conditions. Always refer to the manufacturer’s warranty and guidelines for installation and usage to ensure optimal results.
