Mishimoto 2019+ RAM 6.7L Cummins Thermal Bypass

Your Ram 2500's transmission is key to handling the torque from its 6.7L Cummins engine, but all that power generates heat. This Mishimoto thermal bypass valve kit is designed to help manage that heat more effectively. The stock valve controls when transmission fluid flows to the cooler, but its thermostat can fail, leading to overheating. This kit replaces the stock unit with an improved design that ensures fluid reaches the cooler sooner.

This valve is CNC-machined from aluminum and features a replaceable thermostat that opens about 10 degrees Fahrenheit earlier than the stock one. This means fluid gets to the cooler quicker, improving heat dissipation without causing the transmission to run too cool. For owners in warmer climates, a special bypass is included that allows full flow to the cooler regardless of temperature, and it's easily swapped with just a wrench. The valve body itself has cooling fins machined into it, adding another layer of heat management, and it flows better than the stock valve in both configurations.

Built to last with a durable black anodized finish, this kit includes the thermal bypass valve, a thermostat, and a bypass for constant cooling. It's a well-built upgrade designed to help keep your transmission running at optimal temperatures.
