Heat is the primary enemy of any heavy-duty transmission, particularly when your Ram truck is used for towing, fleet work, or performance driving. The Mishimoto MMTC-RAM-13SL transmission cooler is a direct-fit solution designed to significantly lower fluid temperatures. This unit replaces the stock cooler with a high-capacity tube-and-fin core, requiring no cutting or modifications to the vehicle for a clean installation.

The Mishimoto cooler features a massive 82% increase in core volume and a 112% increase in external fin area compared to the factory unit. To further improve thermal efficiency, the tubes are equipped with internal fins that increase the fluid-to-surface contact area, ensuring more heat is pulled from the transmission fluid before it returns to the gearbox. With an increased 1.34-quart fluid capacity, this cooler provides the additional thermal overhead needed for demanding conditions.
