Quick Ship SKU #: MISH-MMTC-RAM-15SL Mishimoto MMTC-RAM-15SL Transmission Cooler 15-18 Ram 6.7L Cummins

The stock transmission cooler in your 4th Gen Ram does an ample job of keeping temperatures down, but as the loads increase, so do transmission temps. The Mishimoto transmission cooler for your 2015-2018 RAM 6.7L Cummins utilizes a tube-and-fin core with internal fins to balance flow with efficient cooling. With a massive 112% greater core volume, 237% increase in fin area, and 226% increase in fluid capacity, this trans cooler is a huge improvement over the stock unit. To make even better use of that extra core volume, the transmission cooler utilizes fins within the tubes to not only add more cooling surface area, but also ensure more of the fluid contacts the tube, leading to better cooling efficiency. All these improvements make the Mishimoto transmission cooler the ideal replacement for your stock transmission cooler.

Installation of this Cummins transmission cooler requires no cutting or other modifications and includes all hardware needed for a fast and easy install. Like all Mishimoto products, this transmission cooler is backed up by our Lifetime Warranty with Accident Protection for worry free cooling as long as you own it.
