From street and towing to full race, BD Builds Them Best!


Your transmission was only designed to handle the torque and horsepower the stock engine delivers, and in the case of some Dodge models, even the stock torque can present a challenge. So when you start adding power modules, turbo upgrades and other bolt-ons, it’s only a matter of time before the transmission wears out and eventually fails.
 
BD transmissions are built specifically to handle the high torque loads of diesel engines at our state-of-the-art transmission facility. We re-program the valve body for higher line pressure, and add heavy-duty clutches with up to 25% material than stock. The stock thrust washers, which disintegrate and leave metal filings in your transmission, are replaced with roller Torrington bearings. We can upgrade early 47RE transmissions with more rugged 48RE components, even add billet steel input shafts for extreme applications. Each valve body is tested to ensure proper function before we bolt on one of our rigid aluminum transmission pans, which not only adds extra capacity, but reduces case flex. Finally, each transmission is dyno-tested to make sure it functions properly in all gears before it is shipped to you in one of our containers. 

Our transmission packages include an auxiliary full flow filter kit and a PressureLoc on 1994-2004 model years.  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. 

Other options to consider when replacing your transmission are to mate the BD transmission with on of our Torque Converters and Flex Plates for added performance and strength. Call for details—we’ll be happy to answer your transmission questions.
