Enhance the durability and performance of your Ford F-250 Super Duty with the BD Diesel 4R100 Transmission and Converter Package, designed for models from 2000 to 2003. This comprehensive upgrade includes a fully rebuilt transmission featuring a high-performance stage 4 shift kit with line mod valve to increase pressure and improve shift firmness, along with a reinforced aluminum deep pan that increases oil capacity by six quarts for better cooling and lubrication. The transmission incorporates drilled and tapped feeds to prevent leaks, a re-calibrated accumulator body for precise control, and a fully rollerized geartrain to ensure long-term reliability under heavy-duty conditions. Clutch counts have been increased across the board—intermediate by 33%, overdrive by 33%, forward by 25%, and low reverse by 17%—to handle higher torque loads and towing demands. Each transmission is dyno tested to guarantee performance, and the package includes an upgraded torque converter with an enhanced stall for street and towing applications, featuring a cast aluminum stator for improved torque multiplication and efficiency. The converter’s lower RPM response translates into better fuel economy and less heat generation, extending component life. Additional features include a furnace-brazed steel front cover with fins for heat dissipation, an upgraded snap ring, and a machined center support for increased robustness. This package also includes an auxiliary full-flow filter kit for 1990-2003 models, ensuring clean fluid flow for prolonged component life. Designed with heavy-duty applications in mind, this assembly improves drivetrain durability, provides smoother shifts, and ensures reliable operation under demanding conditions. Each unit is built to meet the rigorous standards of fleet and commercial use, backed by a 36-month/150,000-mile parts warranty and a 12-month/24,000-mile labor warranty. Proper installation and break-in procedures are essential for optimal performance and longevity of this high-performance transmission and torque converter package.
