The backbone of your 2013–2018 Dodge Ram 6.7L Cummins is the transmission.
It’s responsible for transmitting up to 930 lb-ft of torque from the engine to the wheels.
That much power generates a lot of heat, and if that heat isn’t dissipated, it can destroy your transmission.
The transmission cooler does a good job of keeping transmission fluid temperatures in check, but only if the fluid can reach it.
Both the 68-RFE and Aisin AS69RC stock cooling systems utilize an in-line thermal bypass valve that controls the flow of fluid to the transmission cooler.
The purpose of this valve is to prevent transmission fluid from flowing to the cooler until it reaches operating temperature.
However, the thermostat inside this valve is prone to failure, and when that happens, the fluid never flows to the cooler, leading to transmission overheating.
That’s why an improved thermal bypass valve kit has been developed by Mishimoto for your 2013–2018 Dodge Ram 6.7L Cummins.
The CNC-machined aluminum thermal bypass valve not only looks better than the stock unit but also performs better.
The Mishimoto thermal bypass valve utilizes a replaceable thermostat that is more durable than the stock thermostat and opens about 10°F earlier.
This allows fluid to flow to the cooler sooner without overcooling.
For owners in hot climates, the Mishimoto valve includes a bypass that allows full flow to the transmission cooler, regardless of temperature.
The bypass can be easily swapped out with only a wrench for summer or winter driving.
The Mishimoto thermal bypass valve flows better in both configurations than the stock valve for more effective cooling.
Machined cooling fins in the valve body add even more heat dissipation.
This Thermal Bypass Valve Kit for the 2013–2018 Dodge Ram 6.7L Cummins is built to last a lifetime with a durable black anodized finish and includes the Mishimoto Lifetime warranty.
