BD Diesel Shift Kit – Chev Allison 1000 2001-2005 5spd – Part # 1604720

The BD Diesel Shift Kit with part number 1604720 is designed to optimize shifting performance in various Chevrolet Silverado 2500 HD models equipped with the Allison 1000 transmission from 2001 to 2005. This comprehensive kit includes our exclusive smart trim and clutch control valve assemblies, which enhance durability and shift quality under demanding conditions. Installation requires transmission removal to access internal components, making it a task best suited for experienced technicians familiar with heavy-duty transmission systems. Once installed, the shift kit provides short, crisp, and smooth upshifts and kickdowns, improving drivability and response during towing or heavy-duty use. It effectively addresses common transmission issues such as going into neutral under load, sticking in one gear, or failure to move after extended parking. The kit is engineered to handle up to 500 street horsepower, making it suitable for high-performance diesel applications while maintaining long-term reliability in fleet operations.

Features:

• Heavy-duty performance: Supports up to 500 street horsepower, ideal for demanding diesel applications

• Premium friction materials: Ensures smooth engagement and reduces wear on internal components

• Enhanced thermal capacity: Prevents clutch slippage during severe towing or high-load conditions

• Reliable shifting: Addresses common transmission issues such as neutraling under load, sticking in gear, and pump prime loss
