Fully remanufactured 47RE transmission featuring the BD Valve Body! The BD Valve Body has many modifications to improve shift quality and extend transmission life. The RoadMaster transmission also includes a deep sump oil pan for increased fluid capacity and cooling. Combining the upgraded VB with increased line pressure and a ProForce torque converter, the BD Roadmaster 47RE transmission is a reliable upgrade for stock or mildly upgraded 5.9L Cummins-equipped Dodge Ram 2500/3500 series trucks.
