The BD-Power 48RE Race Transmission allows you to put some serious power to the ground in your 2003-2007 Dodge 5.9L Cummins. Your factory transmission was designed to handle the torque and horsepower the stock engine delivers, and in the case of some Dodge models, even stock power levels can present a challenge. So when you start adding power modules, turbo upgrades and other bolt-ons, to your purpose built race truck, it’s only a matter of time before the transmission fails. 

BD-Power Race Transmissions are specifically designed to handle competition use in the most extreme applications. These transmissions are built at BD-Power’s the state-of-the-art transmission facility. BD-Power re-programs the valve body for higher line pressure, and adds heavy-duty clutches with up to 25% more material than stock. The stock thrust washers, which disintegrate and leave metal filings in your transmission, are replaced with roller Torrington bearings. BD-Power also installs a new billet input shaft & output shaft for applications with extra big tires and modified power levels.

Inside each transmission is a new design valve body that achieves up to 80% higher clutch apply pressures over the stock unit and up to 50% over the competitors with the pressure increase starting at much lower engine rpm’s and at lighter throttle pedal position movement. Light throttle shift firmness is also maintained at these higher apply pressures and no shuttle shifting problems.

BD-Power Transmission packages include a BD rigid aluminum heavy duty transmission pan which adds extra oil capacity and reduces case flex, plus, includes a BD auxiliary full flow filter kit for extra protection. Each transmission is dyno-tested to make sure it functions properly in all gears, then the pan is dropped and everything inspected and adjusted before it is shipped to you.
