At Next Gen Diesel, we offer excellent support for Dodge's 48RE Transmission, as used in the 6.7L Cummins Ram 2500/3500! Dodge began using the 48RE Transmission in these trucks in model year 2003, as successor to the 47RE. This transmission coexisted with the 47RE for one model year, 2003, and can be differentiated by VIN. Our product catalog includes complete transmissions, total rebuild kits, valve bodies, torque converters and parts. View our 48RE transmissions and parts here!
