There's no greater enemy for a transmission than heat. Whether your 2019+ 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 2019+ RAM 6.7L Cummins transmission cooler utilizes a tube-and-fin core with internal fins to balance flow with efficient cooling. Our transmission cooler reduces restriction over stock, while adding cooling performance. With a massive 64 percent thicker core and an additional 3 rows of fins, this trans cooler is a huge improvement over the stock unit. To make even better use of that enlarged core, 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 translate to lower inlet temperatures over stock for a cooler transmission when you need it most.--Installation of the Mishimoto 2019+ RAM 6.7L Cummins transmission cooler requires no cutting or other modifications and, thanks to the bolt-on mounting tabs, your radiator and A/C condenser can stay in place, reducing the time and cost of installation. 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.
Automatic transmission oil cooler designed to regulate fluid temperature and prevent overheating. Enhances transmission longevity, maintains performance, and features durable construction with a precise fit.
