1998.5-2002 Ram 5.9L Cummins Complete Transmissions

Whether the stock transmission on your Ram 5.9L Cummins is feeling a bit tired or if you're stacking on some serious power-adders to your diesel Ram, Tier One has you covered with a selection of built 47RE transmissions for 1998.5-2002 Ram 5.9L Cummins 2500 and 3500 trucks. Each of our transmissions comes with new internal and external transmission parts that can handle more horsepower than the stock 47REs, as well as survive tough applications both on and off the road. Tier One's 47RE transmissions can handle extremely heavy towing, fast street driving, aggressive off-roading, hard drag racing launches, and strong runs at the dyno day. We here at Tier One offer up a variety of 47RE transmission configurations so that you can find the one that's perfect for your Ram's power level or application. Even the best transmission build needs a reliable connection to the engine, so if you are piecing together your own build or need a specific stall speed, look at our 1998.5-2002 Ram 5.9L Cummins Torque Converters.
