2004.5-2007 Ram 5.9L Cummins Transmission Parts

Your Ram's 5.9L Cummins can easily put down more power than your truck's stock transmission can handle. That's why upgrading your OEM transmission with Tier One's selection of high-quality transmission parts for 2004.5-2007 Ram 5.9L Cummins 2500 and 3500 trucks can really save your bacon. Our upgraded transmission parts can handle way more power than stock and help keep your Ram 5.9L Cummins running smooth no matter how much power your truck makes. Tier One's Ram 2500 & 3500 transmission parts are perfect for aggressive street trucks, tough off-road rigs, purpose-built drag racing trucks, and immensely powerful dyno day rigs. We have billet multi-disc torque converters, billet internal parts, improved clutch packs, deep transmission pans, and much more! If you are finding that you need to replace too many individual parts, it might be more cost-effective and reliable to swap the entire unit, so save yourself the headache of a rebuild with our 2004.5-2007 Ram 5.9L Cummins Complete Transmissions. One of the most critical parts for towing performance isn't inside the transmission case, but attached to the engine, so if you are upgrading hard parts, don't forget to grab one of our heavy-duty 2004.5-2007 Ram 5.9L Cummins Torque Converters. Upgraded hard parts can handle more power, but they still need to be kept cool to last, so protect your new parts and seals from thermal breakdown with our 2004.5-2007 Ram 5.9L Cummins Transmission Coolers. While billet shafts and pans are great, the "brain" of your transmission controls how well they work, so for better shift timing and higher line pressures to clamp your new clutches, look at our 2004.5-2007 Ram 5.9L Cummins Valve Bodies.
