Description
BD Diesel
Transmission
This upgraded transmission is built to improve durability, shift quality, and reliability for both street and towing use. It features an upgraded valve body, upgraded governor solenoid, and upgraded governor pressure transducer (47RE/48RE), delivering twice the burst pressure of stock and increasing line pressure to 190–200 PSI. Shuttle shifting issues are eliminated, and a modified manual valve ensures proper lubrication in all gear positions.
Factory thrust bushings are replaced with roller-style Torrington bearings to reduce friction and increase longevity. Clutch capacity is significantly increased with 6 direct clutches, 5 forward clutches, 6 overdrive clutches, and 10 overdrive direct clutches. A high-temperature, high-energy Raybestos band, combined with a billet band lever and billet band strut, provides superior holding power under load.
Strength is further enhanced with a billet “Big” fine-spline input shaft, designed to absorb shock from rapid throttle inputs and high-horsepower applications. A drilled intermediate shaft improves lubrication for increased reliability.
Cooling and fluid capacity are improved with a BD rigid aluminum heavy-duty transmission pan, which adds 2 quarts of additional fluid capacity. Integrated heat-dissipating fins help control operating temperatures, while a magnetic drain plug captures metallic debris. Additional protection is provided by a BD auxiliary full-flow filter kit, and a cooler line case saver is installed in every transmission. Each unit is dyno tested to ensure proper performance before delivery.
Torque Converter
The torque converter features an enhanced stall speed optimized for street and towing applications. Machined pistons and heavy-duty springs absorb engagement shock, while a stamp-forged, one-piece cover eliminates warpage caused by clutch heat. The taller cover design allows for more rebuild cycles over the life of the converter.
A trapezoid tooth design with tighter tolerances improves torque transfer, while self-centering teeth increase contact area to reduce wear and chatter. Thrust bearings are used instead of plastic thrust washers for improved durability. A precision riveting process ensures proper alignment and eliminates vibration or embrittlement associated with welding. The cast stator design maximizes torque multiplication, and new sprag components ensure long-term reliability. Overall weight is reduced by 12 pounds compared to competing designs.
