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

Lots of squeakers in this one!
Color: Gator, Size: Large
Our rescue dog is a power chewer so this one doesn't last long, but I still gave 5 stars because it's not advertised for power chewers, so I knew what we were getting when we bought it. So why did I buy this for our dog? The number of squeakers... the dog goes nuts for those and it makes the toy last longer because she will only play with the ones that still squeak.

NOT for aggressive chewers!
Color: Lion, Size: Medium
My aggressive chewer had destroyed this in 3 minutes! Chewed off the ears, and chewed apart the body to try to get to the squeaker - it was in the trash 5 minutes after I gave it to him! Yes, the seams are tough, but he easily chewed around them. Don’t buy this if your dog is an aggressive chewer!

Somewhat durable.
Color: Elephant, Size: Small
My dog loves these toys, I think it's the squeaker. I've tried several and this elephant one holds up the best.

Not tough enough
Color: Elephant, Size: Small
It might be tough, but my 26 pound dog managed to rip it open in record time! The only good thing, the squeaker is a long plastic one and easier to grab before she can swallow it!

Cute and tough!
Color: Elephant, Size: Small
Update Dec 2025, still going! This toy has been the subject of much squeaking and death shakes... And more than one tug o' war... And other than looking a little dingy even after washing it's as good as new! No missing bits, no noticeable damage. I have several in the brand, both the larger version for my mastiff, and other styles for the medium-sized dogs. I started buying online because the one store that carries it moved further away. Outshines all other brands I've tried for durability and fun play. In 5years and 9 dogs only 2 have needed replacement. Worth the price!!!
