Product Description

The Mishimoto MMTC-RAM-10 is a high-performance direct-fit transmission cooler engineered specifically for 2010-2012 Ram 2500 and 3500 trucks equipped with the 6.7L Cummins engine. It replaces the OEM cooler with a tube-and-fin design that significantly enhances cooling capacity - boosting core volume by 60% and fin area by 86%. Ideal for trucks used in towing or heavy-duty hauling, it helps maintain optimal transmission temperatures under demanding conditions.

This cooler adds approximately 0.7 quart of fluid capacity, further improving heat dissipation. It installs easily using factory mount points and lines, with no drilling or coolant system modification. Plates and adapters are included for seamless integration with the OEM intercooler and A/C condenser bypass setup.

Fitment has been confirmed via Summit Racing, Blackline Performance, and Mishimoto official documents. Compatible with both 4WD and RWD configurations across all trims - including SLT, Laramie, Laramie Longhorn, Power Wagon, etc. - fitment is guaranteed through 2012. 2013 fitment for the cooler alone is unverified; the bypass kit (MMTC-RAM-10LK) lists 2013 support but this cooler does not.
