To some it is a challenge to simply disassemble and assemble a Ford transmission. For BD, the challenge was to improve the durability and performance of these transmissions in demanding, high-torque diesel applications.

The smooth shifting associated with the stock Ford transmission is the result of slippage that produces heat and accelerates wear. BD transmission and converter clutches are made from specialized, high-performance materials, and 33% more clutch surface is added to eliminate slippage.

A re-programmed valve body with improved valve designs, higher line pressure and enhanced oil flow creates positive clutch apply, which results in quick, sharp shifts. A BD deep-sump aluminum pan is also fitted, which increases oil capacity for cooler operation.
The planetary gear packs are made from high-strength steel, and heavy-duty, one-way roller Sprague clutches maintain directional stability, unlike the stock or inferior aftermarket products, which can explode.

Finally, each transmission’s shift pattern and oil pressure is tested on our transmission dynamometer, then shipped to you in a virtually indestructible molded plastic container. For ultimate strength and reliability, we recommend you match your new BD transmission with a TorqForce performance torque converter.

Our transmission packages include an auxiliary full flow filter kit for the 1990-2003 7.3L.

NEW WARRANTY : 36-month / 150,000 mile limited warranty on non competitive, racing or sled-pulling applications. See warranty statement for further details. You must have a BD torque Converter with a bd transmisson to obtain a warranty.
