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.  Each unit comes with a one-year parts and labor freight warranty good throughout North America. You can also extend your warranty to 3 years with our Extended Warranty Kit. Call for details—we’ll be happy to answer your transmission questions.
