The transmission is the backbone of your RAM. It's responsible for transmitting large amounts of torque from your 6.7L Cummins powerplant, and that torque generates heat. If that heat isn't dissipated, it can destroy your transmission. The transmission cooler does a good job of keeping trans fluid temperatures in check, but only if the fluid can reach it. The stock cooling system of the Aisin AS69RC utilizes an in-line thermal bypass valve that controls fluid flow 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 a full-flow thermal bypass valve upgrade for your 2019-2024 RAM 6.7L Cummins. Our CNC-machined aluminum thermal bypass valve not only looks better than the stock unit, but it performs better too. This Mishimoto thermal bypass 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. This 2019-2024 RAM 6.7L Cummins Thermal Bypass Full Flow Valve Kit is built to last a lifetime with a durable CNC-machined billet aluminum design and our Mishimoto Lifetime Warranty.

  • Equipped with a bypass for uninterrupted cooling in hot weather conditions
  • Features a fully serviceable thermostat for rapid warm-up in cold weather
  • Helps extend transmission life and prevents overheating

Small but mighty
Color: Chew Pair, Size: Mini (Pack of 2)
Dusty (chihuahua) loves the blue bone! It is the perfect size for his little mouth and he loves that he can put it to the back of his mouth and just chew on it. The rope one is his least favorite as it appears to be too big for his mouth. They’re great quality and while they are not stretchy they do bounce!

The only toys my older Chihuahua likes
Color: Chew Pair, Size: Mini (Pack of 2)
These are the only toys my older Chihuahua likes. They can't be found locally, Thank goodness I can order them and get them here fast. My younger Chihuahua grabs them sometimes and chews big chunks off. Swallowing the chunks would be a concern

Good but watch for the strings coming undone.
Color: Chew Pair, Size: Mini (Pack of 2)
Our 12 week old puppy has loved chewing on these bones. The only issue you'll need to look out for is the knots in the strings come undone very easily. I've had to retire them multiple times. This could be dangerous for dogs that like to eat strings!!
