BD Diesel

This transmission is designed to handle the output of a stock engine while delivering increased durability through carefully selected internal upgrades. Key improvements—such as the hardened pressure regulator valve, upgraded snap ring, and aluminum valve body pressure plugs—address common failure points including run-away reverse pressure, gear slipping, and case lug blowout.

Cooling performance is significantly improved with the BD deep sump transmission pan, which increases fluid capacity and helps maintain lower operating temperatures. Paired with the included ProForce torque converter, this transmission provides reliable performance, smooth operation, and long-term durability.

Built by BD Diesel Performance, this package is an excellent choice for owners of stock trucks looking for a dependable, upgraded replacement transmission with proven reliability.
