The BD Diesel 1064232F TowMaster 48RE Transmission is engineered for enhanced durability and smooth shifting in 2005–2007 Dodge Ram 2WD trucks equipped with the 5.9L Cummins. Built with upgraded internals, clutch packs, and pressure components, this transmission handles higher torque demands and towing loads better than stock. Paired with BD’s auxiliary full-flow filter kit and heavy-duty aluminum pan, it offers increased oil capacity, improved cooling, and a cleaner transmission life. Dyno-tested before shipping and designed with plug-and-play wiring, this is the perfect upgrade for work or street use.
