The Mishimoto transmission cooler for the 2010-2013 Ram 2500/3500 6.7L Cummins is a direct-fit, tube-and-fin upgrade built for heavy towing and rapid load changes, with a 60% increase in core volume and 86% greater external fin area than the stock cooler for superior heat dissipation. It works with the factory or a Mishimoto cooler and pairs with an optional bypass line kit (sold separately) that lets you bypass the factory cooler — useful after a transmission failure where the OEM cooler may be contaminated.
