There's no greater enemy for a transmission than heat. Whether your 2015-2018 RAM 6.7L Cummins is a dedicated tow vehicle, hardworking fleet truck, or a daily driver with a liking for the dragstrip, you need to ensure that your transmission runs cool. Luckily, Mishimoto has developed a direct-fit transmission cooler to do just that. Our 2015-2018 RAM 6.7L Cummins transmission cooler utilizes a tube-and-fin core with internal fins to balance flow with efficient cooling. With a massive 112-percent greater core volume, 237-percent increase in fin area, and 226-percent 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 Mishimoto 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.
