Mishimoto 15-18 Dodge RAM 6.7L Cummins Transmission Cooler

If you use your 2015-2018 Ram 2500 with the 6.7L Cummins engine for towing, hauling heavy loads, or even just spirited driving, keeping your transmission cool is crucial. Heat is the biggest enemy of transmission longevity, and the stock cooler can struggle under demanding conditions. Mishimoto has developed a direct-fit transmission cooler specifically for your truck to combat this issue.

This Mishimoto transmission cooler features a tube-and-fin core design enhanced with internal fins. This setup is engineered to balance fluid flow with effective heat dissipation. Compared to the factory unit, it boasts a massive 112-percent greater core volume, a 237-percent increase in external fin area, and a 226-percent boost in fluid capacity. The internal fins not only add more surface area for cooling but also ensure the transmission fluid makes better contact with the tubes, leading to more efficient heat transfer. Installation is straightforward, requiring no cutting or modifications, and all necessary hardware is included for a quick setup.

This transmission cooler is a solid option for anyone looking to improve their truck's towing performance or extend the life of their transmission. Mishimoto backs this cooler with their Lifetime Warranty, including Accident Protection, giving you peace of mind for as long as you own your truck.
