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.

Handsome watch!
Color: Retro Brown band & Black bezel & Blue dial
My 13 year old grandson wanted an “old fashioned” watch so I gave this one to him. He is obsessed with it and wears it every day.

Don't Waste Your Money
Color: Retro Brown band & Gold bezel & White dial
This watch is a complete disappointment. Right out from the box, I adjusted the time per the instruction manual. After finshing adjusting the watch, I pushed the crown in (two clicks). The second hand started movement after almost 10 seconds. From then on, the second hand was stopping and going by itself. Within less than anhour, the watch was behind almost 25 seconds. It is a piece of junk. I would not advise anyone to buy this watch.

Rough dial, pretty watch
Color: Mesh Strap watch balck
Great looking watch, the dial is rough on the skin, it should be refined some to not have sharp edges.

Great Watch for a Great Price
Color: Dark Brown band & Rose Gold bezel & Navy Blue dial
⌚ “Simple, clean, and gets compliments every time.” ⌚ This Watch has easily become my go-to watch. What I like most is how clean the design is. It’s not flashy, but it stands out in a classy way. I usually pair it with brown shoes and a belt, and it pulls the whole look together perfectly. Another big plus—it doesn’t feel heavy on the wrist. You can wear it all day and forget it’s even there, which is exactly what you want in a daily watch. And the compliments? They come consistently. It’s one of those pieces people notice without you trying too hard. ✔️ Clean, stylish design ✔️ Lightweight and comfortable ✔️ Pairs perfectly with dress or casual outfits ✔️ Gets a lot of compliments If you’re looking for an affordable watch that looks sharp and feels great, this is a solid choice.
