Description
BD Diesel
This performance-built transmission is engineered to handle up to 300% more power and torque than stock while significantly increasing drivetrain durability. It features all-new bushings, a redesigned valve body, revised oil circuits, and a fully rollerized geartrain to reduce friction and improve reliability.
Stock thrust washers are replaced with roller Torrington bearings to protect governor solenoids, while a drilled intermediate shaft and modified manual valve ensure proper lubrication in all gear positions. 47RE units are upgraded with stronger 48RE components, including new input shafts, hub assemblies, and a billet input shaft to absorb shock from rapid throttle and high-horsepower use.
Clutch capacity is increased with heavy-duty clutches offering up to 25% more friction material, machined pressure plates and pistons, a high-temperature Raybestos band, and billet band and accumulator components. Up to 80% higher clutch apply pressure delivers firm, consistent shifts at lower RPM and light throttle input, eliminating shuttle shifting. Additional protection includes an upgraded governor pressure transducer and solenoid, cooler line case saver, and a BD auxiliary full-flow filter kit.
Cooling and strength are improved with a BD rigid aluminum heavy-duty transmission pan, adding 1 quart of fluid capacity, reducing case flex and internal leakage, and featuring cooling fins and a magnetic drain plug.
Clutch counts include Forward (5), Direct (5), Overdrive (6), and Overdrive Direct (10)—making this transmission a proven solution for high-power diesel applications.
