The BD Diesel 4R100 TowMaster Transmission and Converter Package offers a comprehensive solution for heavy-duty Ford F-250 Super Duty trucks from 1999 to 2003. This package features a meticulously matched transmission and torque converter, both dyno tested together to ensure optimal performance and durability under demanding towing, street, or track conditions. The inclusion of a BD aluminum heavy-duty deep pan increases oil capacity by six quarts, aiding in thermal management and extended component life. Designed to handle high torque loads, this transmission incorporates drilled and tapped feeds to prevent leaks and enhances durability with a reworked front pump and a re-calibrated accumulator body.
The torque converter is engineered with an enhanced stall for street and towing applications, providing lower rpm response and improved torque multiplication. Its billet 300M input shaft and fully rollerized geartrain contribute to increased strength and efficiency, reducing heat generation and improving fuel economy during severe duty. The transmission features additional clutch counts across multiple gears—intermediate, low reverse, overdrive, forward, and coast clutch—to significantly boost holding capacity and overall drivetrain resilience.
Built with precision, each unit undergoes dynamometer testing to verify performance standards. Heavy-duty features such as a stamp-forged steel front cover, furnace-brazed fins, and high-pressure components make this package suitable for sustained severe fleet use. The inclusion of upgraded components like the OD snap ring, machined center support, and a reworked front pump ensures quick, firm shifts and reliable operation under high stress. This package is ideal for professionals seeking a robust, high-performance transmission solution capable of supporting increased power demands and extended towing capacity.
Features:
- Heavy-duty diesel and fleet torque capacity for demanding applications
- Premium friction materials for smooth, reliable engagement
- Enhanced thermal capacity to prevent clutch slippage under severe towing conditions
