If there is one thing that could be considered to plague the Dodge Cummins powertrain, it has been the use of their four speed transmissions over the years. The initial units in 1994, dubbed the 47RH, were adequate at best, but considering the low output of these engines, they faired relatively well at stock power levels and moderate towing. Several years later, the 47RE was released, and again, with a stock engine and light loads, they would last for 100,000-150,000 miles. In 2003, with the release of the newer Common Rail Cummins, Dodge unveiled the use of the new 48RE transmission that was labeled as the fix for Dodge’s transmission woes.
While the 48RE is a superior transmission to its predecessors, it is still no match for the potential of the Common Rail Cummins. Even under normal use and with factory horsepower levels, these transmissions would also fail in the 100-150K mile range. Fortunately, with the addition of several aftermarket upgraded components, the 48RE transmission can be built to handle substantially higher horsepower and larger loads, all while lasting considerably longer than the factory unit. For those that have either had a complete failure of the transmission or its simply time for an upgrade, we also offer complete transmission packages in various levels depending on the horsepower and use of the truck.
Whether you are just looking to keep transmission temperatures down with a double deep, finned transmission pan, or a full blown billet transmission, we’ve got you covered.
