BD Diesel 4R100 Transmission & Converter Package – Part # 1064442SM

Enhance the durability and performance of your Ford 4R100 transmission with the BD Diesel 4R100 Transmission & Converter Package, part number 1064442SM. This comprehensive upgrade combines a fully rebuilt transmission with a high-performance torque converter, designed specifically for 2000-2003 Ford F-250 Super Duty trucks. The transmission features a re-calibrated accumulator body for quicker, firmer shifts, and a full shift kit with line mod valve to increase line pressures, resulting in more responsive gear engagement and improved drivetrain control. The addition of an aluminum heavy-duty deep pan increases oil capacity by six quarts, promoting better cooling and lubrication during severe towing or heavy-duty operation.

This package includes an auxiliary full flow filter kit for continuous transmission health and longevity. The upgraded components such as drilled and tapped feeds prevent leaks at case connections, while the machined center support and fully rollerized geartrain ensure long-term reliability. Clutch counts are increased across the board—intermediate, low reverse, overdrive, forward, and coast clutch—providing up to 33% more clutch surface area for enhanced torque capacity. The steel front cover is stamp-forged for added strength, and the furnace-brazed fins improve heat dissipation. The high-performance torque converter features an enhanced stall for street and towing applications, with a lower rpm response than the stock converter for more efficient operation, less heat buildup, and better fuel economy.

Each transmission is dyno tested to ensure quality and performance standards. The package’s design emphasizes increased torque capacity, thermal management, and drivetrain longevity, making it ideal for severe fleet duty, towing, and power-up applications. The parts are covered by a 36-month/150,000-mile parts warranty and a 12-month/24,000-mile labor warranty, providing confidence in long-term durability and service life.
