1998.5-2002 Ram 5.9L Cummins Transmission Coolers

Heat is a killer of 47RE transmissions, and unfortunately, the 5.9L Cummins under the hood of your Ram 2500 or 3500 is extremely good at generating heat, especially if it's rocking extra power or towing heavy loads. That's why Tier One offers a selection of performance transmission coolers for 1998.5-2002 Ram 5.9L Cummins trucks that will keep your Ram's transmission temperatures under control, even if you are getting more power from other performance mods or towing extremely big trailers, fifth wheels, toy haulers, campers, boats, or whatever else. These transmission coolers have more surface area and more efficient designs than the stock coolers which help keep running temperatures lower to keep your truck out of limp mode and preserve the lifespan of your truck's entire transmission. 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 1998.5-2002 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 1998.5-2002 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 1998.5-2002 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 1998.5-2002 Ram 5.9L Cummins Transmission Parts.
