2003-2004 Ram 5.9L Cummins Transmission Coolers

Keeping your Ram's transmission cool is a heck of lot easier said than done, especially if you're towing big trailers, toy haulers, 5th wheels, campers, boats, or if you're rocking extra horsepower and torque from aggressive tuning and big turbos. Luckily for you, we here at Tier One have a nice selection of performance transmission coolers for 2003-2004 Ram 5.9L Cummins trucks that will help keep your truck out of limp mode and improve both the reliability and longevity of your Ram's transmission. These aftermarket Rm Cummins transmission coolers feature larger surface areas, aluminum construction, and more efficient designs that all work together to greatly improve heat dissipation over the stock coolers for much lower transmission temperatures. We have both drop-in transmission coolers as well as universal auxiliary transmission coolers available if you're looking for even more cooling potential. If your truck has already suffered from heat damage and is slipping in gear, a cooler alone won't fix the internal clutches, so you may need to look at replacing the unit with one of our 2003-2004 Ram 5.9L Cummins Complete Transmissions. An unlocking torque converter creates significant friction and heat, so to reduce heat generation at the source while improving towing performance, consider upgrading to one of our 2003-2004 Ram 5.9L Cummins Torque Converters. Sometimes overheating is caused by inefficient fluid routing or cross-leaks inside the case, but you can improve fluid flow and reduce operating temperatures by installing one of our 2003-2004 Ram 5.9L Cummins Valve Bodies. Another great way to help manage heat is by increasing your overall fluid volume, so add several quarts of extra capacity and help dissipate heat by adding a deep pan from our section of 2003-2004 Ram 5.9L Cummins Transmission Parts.
