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.

4 stars
Color: Brown, Size: Rectangle
I like the tray a lot. Quality is very good. Color (Brown) is attractive. Size is perfect for my nightstand. It holds phone, remote, eyeglasses, & phone. I threaded my phone charging cord through a corner of the tray. But it slides too easily off of the nightstand. I'm going to try to find something to stop it from sliding that will stick to the underside of the tray without harming the wood surface on my cherry nightstand.

Better than other flimsy trays
Color: Black, Size: Rectangle, Color: Black, Size: Rectangle
I got this to replace another flimsy valet tray I got as a gift. This one is way more sturdier, looks nicer, bigger, and has a nice feel.

Looks great, doesn't hold much so measure carefully
Color: Gray, Size: Rectangle
I got this organizer for my husband to keep his stuff by the door. While it's a little smaller than I'd hoped, it looks great in the entryway. It's super easy to snap together, but feels like the material could be damaged easily if you're not careful. He is able to store his keys, wallet, and sunglasses in it, and throws hit hat on top. Overall we are really happy with it.
