The Mishimoto transmission cooler for 2010–2012 Ram 2500/3500 with the 6.7L Cummins is a direct-fit tube-and-fin cooler built for heavy towing and repeated load changes. It delivers a 60% increase in core volume and an 86% larger external fin area to improve heat dissipation, and it works with both stock and Mishimoto coolers. An optional line kit lets installers bypass the factory cooler when necessary.
