There's no greater enemy for a transmission than heat. Whether your 2013-2014 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 2013-2014 RAM 6.7L Cummins transmission cooler utilizes a tube-and-fin core with internal fins to balance flow with efficient cooling. With a massive 82% greater core volume, 112% increase in fin area, and 1.34-quart fluid capacity for improved cooling capacity, this trans cooler is a huge improvement over the stock unit. All these improvements make the Mishimoto transmission cooler the ideal replacement for your stock transmission cooler. Installation of the Mishimoto 2013-2014 RAM 6.7L Cummins transmission cooler requires no cutting or other modifications.
