Mishimoto 10-12 Ram 2500/3500 6.7L Cummins Transmission Cooler

This Mishimoto transmission cooler is built with a tube and fin design, specifically chosen for its effectiveness in heavy load towing and situations with rapid load changes. It offers a substantial 60% increase in core volume compared to the stock unit, which means it can handle more transmission fluid and dissipate heat much more efficiently. This is crucial for keeping your transmission running cool, especially when you're pushing your 2011-2013 Ram 2500 or 3500 with the 6.7L Cummins engine to its limits.

Beyond the increased core volume, this cooler also boasts an 86% larger external fin area. Those fins are where the magic happens, allowing for superior cooling and heat dissipation by exposing more surface area to the airflow. Mishimoto also offers an optional line kit that allows you to bypass the factory transmission cooler. This is a smart move because if your factory transmission ever fails and contaminates the fluid, that contamination can easily spread to the factory cooler, potentially causing a cascade failure. By bypassing it, you protect your new Mishimoto cooler from any lingering issues.

This transmission cooler is designed as a direct fit for your truck, making installation more straightforward. It's a well-built component that addresses a common concern for Cummins owners who use their trucks for work or serious towing, helping to extend the life of your transmission.
