The BD Diesel 1064462 transmission is engineered specifically for heavy-duty Ford trucks, including the 2003-2004 Ford F-250 and F-350 Super Duty models, providing enhanced durability and power handling. This transmission features a fully rollerized geartrain and a revised oil circuit system that significantly increases overall strength and reliability. With an added 6-quart oil capacity thanks to the integrated aluminum deep pan, it effectively reduces case flex, minimizes internal oil leakage, and enhances heat dissipation with heat-dissipating fins, ensuring optimal operating temperatures under severe towing and high-performance conditions. The design incorporates additional clutches—up to 20-67% more than stock—and upgraded internals such as sprags, planetaries, and supports to handle up to 300% more power and torque, making it suitable for demanding commercial applications. The inclusion of high-quality components like a heavy-duty snap ring, blow-off valve, and an upgraded sump filter further prevents runaway pressure and internal damage, providing a robust solution for fleet and heavy-duty use.
Features:
- Heavy-duty torque capacity handling up to 300% more than stock for severe towing and power applications
- Premium friction materials for smooth, consistent engagement and longevity
- Enhanced thermal capacity with heat-dissipating fins and oil cooling features to prevent clutch slippage under high stress
- Long-term drivetrain reliability with upgraded internals, increased clutch counts, and reinforced structural components
