There's no greater enemy for a transmission than heat. Whether your 2019-2024 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 2019-2024 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. All these improvements translate to lower inlet temperatures over stock for a cooler transmission when you need it most. ---- Installation of the Mishimoto 2019-2024 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.
