Product Information

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% greater core volume, 237% increase in fin area, and 226% increase in fluid capacity, this trans cooler is a huge improvement over 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. All these improvements make the Mishimoto transmission cooler the ideal replacement for your stock transmission cooler. Installation of the Mishimoto 2015-2018 RAM 6.7L 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.
