Keep your transmission in your 13-18 6.7L Ram Cummins running cool and prevent future failures with the Mishimoto Thermal Bypass Valve kit. The stock cooling system of both the 68-RFE and Aisin AS69RC 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. The thermostat inside this valve is prone to failure, however, and when that happens, the fluid never flows to the cooler and the transmission can overheat. That’s why Mishimoto has developed an improved thermal bypass valve kit for your 2013–2018 Dodge Ram 6.7L Cummins.

Mishimoto Thermal Bypass Valve - Thermostat Controlled: This 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. Cooling fins machined into the valve body add even more heat dissipation.

Mishimoto Thermal Bypass Valve - Full Flow: This valve eliminates the internal thermostat, providing full fluid flow to the transmission cooler in all running conditions. This setup is ideal for owners in warm climates, those performing heavy towing, and trucks needing the best possible cooling efficiency for their transmission. The Mishimoto full-flow thermal bypass valve features strategically machined internal passages, providing improved flow over the stock valve for more effective cooling. In addition, cooling fins machined into the valve body add even more heat dissipation.

Soft and Restful Sleep
Color: White, Size: Queen Size Set of 2
I’ve been using this set of pillows and I really like the comfort they provide. They are soft to the touch but still offer the right support for my neck and head, helping me sleep more relaxed and wake up without tension. They also feel cool throughout the night, making my rest more comfortable and uninterrupted. I love this pillows!

Hotel-like comfort at home I bought these pillows from Beautyrest and they really exceeded my expectations. They are very soft but at the same time have good support, which helps you rest better throughout the night. They feel like luxury hotel pillows, especially because of their down-like filling. The jumbo size is perfect and they come well filled, they are not easily crushed. In addition, the cotton cover feels fresh and of good quality. They arrived quickly and well packed. After using them for several days, they maintain their shape and comfort. I definitely recommend them if you are looking to improve your rest without spending too much.
