68RFE Transmission Coolers - Drop-In & Auxiliary Transmission Coolers

The 6.7L Cummins Rams with 68RFE transmissions tend to run on the hot side, even if they're bone-stock and driving on the street, but things get even spicier when your Ram is running aggressive tunes or towing extremely. The 68RFE transmission is no fan of heat, and keeping it in within a safe operating temperature is absolutely critical if you want it to last. Tier One's selection of performance 68RFE transmission coolers will keep your Ram's transmission temperatures down, even if your Ram 6.7L Cummins of choice is throwing down more power or towing extremely heavy. We here at Tier One carry both easily-installed drop-in transmission coolers from Mishimoto, as well as powerful auxiliary transmission coolers that are perfect for dedicated towing rigs or race trucks. Make sure you also check out our 68RFE transmission pans or our 68RFE thermal bypass valves!
