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.

So pretty
This product is so versatile. At cheer it is used to give the girls an extra sparkle. For general makeup use it is used to highlight specific areas. The sparkle it gives is very flattering. It is the one item that the team can all agree on.

They work! Even if you hate socks
I am not a sock wearer. Can't stand having my foot entirely shrouded in cloth. I don't wear socks with my sandals, slides, clogs and other shoes most of the year. Only on the coldest winter days. I know, It's weird. So, with my sock phobia one thing that happens is your heals get dry and rough. I opted to try these because the toes are free. I barely notice the socks on my heels/ankles when my toes get air (outside of bedcovers always). I put good thick lotion on my heels and sides of feet. A little less on the toes so they don't stain anything. The silicone lining on the heel holds that lotion against the affected areas. In a couple days my feet felt soft and looked pretty. No cracks, no white roughness. They look pink and freshly spa-ed. Fit is good on size 9 feet with thickish ankles. Highly recommend.

Nice Socks, Bad Shipping
The socks are definitely worth the price. They are cozy and non constructive. They colors are nice. My only complaint is the method in which it was shipped. Slapping a mailing label on a clear bag is not acceptable. The shipper didn't consider protecting my privacy. I hate to think if it was something extremely private. Consumers deserve better when it comes to the content of their mail.

There’s room for improvement
These heel support socks are quite comfortable to wear, the cotton blend fabric is soft and breathable. The built-in gel continuously moisturizes the heels, and the effect is more noticeable than applying lotion alone. I usually soak my feet in warm water before bed, apply lotion, and then use these socks. The elasticity is just right, and they don't constrict my feet. If the gel coverage area were a bit larger, the protection would be more comprehensive. Overall, they offer good value for money and are a practical foot care item.

They worked
I got these for my elbows because I think I might have eczema on my elbow. They work very well. However I do wish they were a little looser. As far as putting them on your heels, the fit works well.
