The Mishimoto Transmission Cooler Thermal Bypass Valve Kit for the Ram 6.7L Cummins is the perfect solution to one of the biggest transmission cooling flaws in your truck.
The stock thermal bypass valve is supposed to regulate fluid flow to the transmission cooler, but when it fails, it can block fluid completely, leading to overheating and serious transmission damage. Mishimoto’s upgraded bypass valve ensures that never happens, keeping your transmission cool and performing at its best no matter what you throw at it. Crafted from CNC-machined billet aluminum, this valve isn’t just built to last, it’s designed for maximum cooling efficiency. Strategically machined internal passages improve flow over stock, while built-in cooling fins help dissipate heat even further. The direct-fit design ensures a hassle-free installation, getting you back on the road with confidence.
Available in two options, this kit lets you choose the best setup for your needs:
- The full-flow valve eliminates the thermostat entirely, allowing transmission fluid to circulate through the cooler at all times, making it the ideal choice for hot climates, heavy towing, and high performance applications.
- If you’re looking for a more controlled approach or operate in a consistently cold climate, the upgraded high flow thermostat valve features a replaceable thermostat that’s far more durable than stock and opens 10°F earlier, allowing fluid to reach the cooler sooner without overcooling. This option also includes a bypass insert, so you can easily switch between thermostat controlled and full-flow modes with just a wrench.
Whether you need maximum cooling all the time or a smarter way to regulate transmission temps, Mishimoto has the solution to keep your truck running cool and strong.

Our pup loves the cronch cronch!
Style: Ball, Size: Medium (Pack of 1)
I bought our 15 month old Coton several Chuck-It toys on an Amazon deal. He is incredibly playful, mischievous, and ball/toy obsessed, especially for anything that makes noise. He can also be very destructive so I love how durable most of their products are - they’re among our longest lasting toys and worth every penny. We have yet to take them to the dog park, but they’re a perfect size for sharing in play time. And they are keeping him busy at home - that’s a good thing.
He loves investigating the crunchy-cronchy-crinkly sound which is a nice change from squeakers. It can withstand his destructive chewing well-being, gentle on his little teeth. I love that. Chuck-It is thinking outside the box with a variety of balls to keep dogs engaged! I do worry about the crinkle plastic inside because it is accessible because of the air holes and it feels a little sharp. So this will have to be an at home toy so we can monitor his play.

My dog loves it!
Style: Ball, Size: Medium (Pack of 1)
This crunch ball was a Christmas gift for my 65lbs fur baby. It’s now mid April and he still loves it. He loves running after it and chomping down on it. It is still in good shape despite all the chomping it’s gotta . I highly recommend. He goes back to this toy agin and again! Great buy.

Our first babies favorite and longest lasting ball yet and he is fixing to be 7.
Style: Ball, Size: Medium (Pack of 2), Style: Ball, Size: Medium (Pack of 2)
Toughest ball we have found yet. Our doberman loves Chuckit! Balls especially the crunch one. He spreads all the balls and toys we have bought but these lasted the longest. The crunch and the glow in the dark are usually his pick but he has several different choices.
