Description
The Mishimoto MMTC-RAM-03SL is a silver-finished transmission cooler engineered specifically for the Dodge Ram 5.9L and 6.7L Cummins trucks built between 2003 and 2009. As a purpose-built Mishimoto trans cooler, it’s designed to bolt into the platform it was made for rather than serve as a generic, one-size-fits-all fluid cooler.
Heat is one of the fastest ways to wear down automatic transmission fluid, and a dedicated Mishimoto transmission cooler like this one gives your Cummins-powered Ram a focused way to manage that heat. Whether you’re towing, hauling, or simply putting daily miles on a hard-working diesel truck, having a Mishimoto oil cooler in the cooling system helps keep transmission fluid operating in a healthier range. This Mishimoto cooler carries the brand’s silver finish and is cataloged under Cooling parts for the Ram Cummins lineup, making it a straightforward, model-specific upgrade for owners who want a transmission cooler built for their exact truck.
