There’s no greater enemy for a transmission than heat. You need to ensure that your transmission runs cool. Luckily, Mishimoto has developed a direct-fit transmission cooler to do just that. Their 2015-2018 Dodge Ram 6.7L Cummins transmission cooler utilizes a tube and fin core with internal fins to balance flow with efficient cooling.The Mishimoto transmission cooler is not only larger than the stock, but more reliable too. When the stock cooler’s thermostat fails, it fails closed, bypassing the cooler and returning hot fluid to the transmission. Mishimoto has solved this common issue by utilizing 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.
