BD Diesel
Transmission
This upgraded transmission is built to handle increased power while maintaining excellent street and towing drivability. 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. The modified hydraulic system eliminates shuttle shifting issues, while a reworked manual valve ensures proper lubrication in all gear positions.
Factory thrust bushings are replaced with roller-style Torrington bearings to reduce friction and improve longevity. Clutch capacity is significantly increased with the following clutch counts: Direct – 6, Forward – 5, Overdrive – 6, and Overdrive Direct – 10. A high-temperature, high-energy Raybestos band, along with a billet band lever and billet band strut, provides improved holding power and durability.
To handle high-horsepower applications, this transmission is equipped with a billet “Big” fine-spline input shaft, designed to absorb shock from rapid throttle inputs. The intermediate shaft is drilled to improve lubrication under load.
Cooling and fluid capacity are enhanced 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, and a magnetic drain plug captures metallic debris. A BD auxiliary full-flow filter kit adds an extra layer of protection, while a cooler line case saver is installed in every transmission. Each unit is dyno tested to ensure proper operation and reliability.
Torque Converter
The included 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 in place of plastic thrust washers for added durability. A precision riveting process ensures 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.
Warranty
This transmission is backed by a 36-month or 150,000-mile parts warranty, with 12 months or 24,000 miles of labor coverage.
