Mishimoto 2019+ Ram 6.7L Cummins Transmission Cooler

Mishimoto is known for making well-built cooling components, and this transmission cooler for your 2019 and newer Ram 2500 or 3500 with the 6.7L Cummins engine is no exception. Whether you're hauling heavy loads, running a fleet, or just pushing your truck hard, keeping your transmission temperatures in check is crucial. This direct-fit cooler is designed to handle that job effectively.

This transmission cooler uses a tube-and-fin core that's not only efficient but also incorporates internal fins. These internal fins do two things: they increase the surface area for better heat dissipation, and they ensure more of the transmission fluid makes contact with the cooling tubes, leading to improved cooling efficiency. Compared to the stock unit, this Mishimoto cooler features a core that's 64% thicker and has an additional three rows of fins, significantly boosting its cooling capacity while still balancing flow. This means lower inlet temperatures for your transmission, especially when it's working its hardest.

Installation is straightforward because it's a bolt-on design. The mounting tabs allow you to keep your original radiator and A/C condenser in place, meaning no cutting or modifications are needed, which saves you time and money on the install. Mishimoto backs this transmission cooler with their Lifetime Warranty, which includes Accident Protection, giving you peace of mind for as long as you own your truck.
