Mishimoto’s transmission cooler is designed to be a direct fit for the 2010-2012 Dodge 2500/3500 6.7L Cummins and features a tube and fin design optimal for heavy load towing and rapid load changes. This transmission cooler boasts a 60% increase in core volume and an 86% increase in external fin area for superior cooling and heat dissipation. It also pairs with an optional line kit that helps bypass the factory transmission cooler, as a transmission failure can contaminate that.
