Mishimoto 2013+ Dodge Ram 6.7L Cummins Thermal Bypass Valve Kit

The transmission in your 2013-2018 Ram 2500 or 3500 with the 6.7L Cummins engine handles a lot of torque, and that means heat. While the stock transmission cooler is designed to manage this, it relies on a thermal bypass valve to control fluid flow. This stock valve has a thermostat that can fail, preventing fluid from reaching the cooler, which can lead to transmission overheating. Mishimoto's full-flow thermal bypass valve upgrade is designed to address this common failure point.

This kit replaces the stock valve with a unit that's CNC-machined from billet aluminum. It eliminates the internal thermostat, ensuring that transmission fluid constantly flows to the cooler, regardless of temperature. This is especially beneficial for trucks used in warm climates, those frequently towing heavy loads, or any truck owner looking to maximize transmission cooling efficiency. The internal passages are machined to improve flow over the factory part, and cooling fins are integrated into the body to help dissipate heat. The silver anodized finish not only looks good but also adds durability.

This kit is a direct replacement for the stock valve and installs in under an hour. It's a well-built upgrade designed to help keep your transmission running cool and prevent costly damage.
