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.

Excellent quality - great buy! Looks sharp!
Size: Large, Color: Gray, Size: Large, Color: Gray
Great quality - this is a medium weight coat. Perfect as a car coat but too thin for cold winter days if you had to be outside for long periods of time. The fit is just perfect. Purchased a size large for a man 5’6 175 lbs with a small belly so peacoat double breasted look - looks great! Lining is standard and the grey color is very appealing. This is soft feeling coat made to look like wool without the heavy rougher wool feel. Only issue is that the coat comes packaged in a small bag and so when you open it the coat it totally wrinkled. You can knock out the wrinkles in the dryer with a wrinkle release dryer sheet or use a garment steamer but honestly the dryer trick is the key.

Long enough sleeves for a tall guy
Size: Large, Color: Green
I’m 6’3” and skinny, and was very impressed to find the sleeves were long enough for me in a large! The overall fit of the coat is boxy or straight, while I would have preferred a slimmer cut, I’m just so happy that the sleeves fit! The liner is nice, interior breast pockets on both sides are super convenient, and I love the green.

A Timeless and Stylish Pea Coat - Perfect for Winter!
Size: X-Large, Color: Wine Red
The quality of this pea coat is exceptional. The wool blend material feels soft and luxurious, and the craftsmanship is evident in every stitch. The coat is well-constructed and designed to withstand the test of time. I have been wearing it throughout the winter season, and it has kept me warm and cozy even during the coldest days. The classic double-breasted design of the coat is timeless and versatile. It adds a touch of sophistication to any outfit, whether I'm wearing it for a formal event or a casual day out. The notched collar enhances the coat's elegance and provides a polished look. The fit of the coat is excellent. The sizing chart provided by the seller was accurate, and the coat fits me perfectly. The tailored cut gives it a flattering silhouette without feeling restrictive. It allows for comfortable layering, so I can wear sweaters or jackets underneath without any issues. One of the standout features of this pea coat is its attention to detail. The buttons are well-placed and secure, and the lining is smooth and comfortable against the skin. The deep pockets are a great addition and provide ample space for storing essentials like gloves or a phone.
