Why ATS Thermal Bypass Valve Upgrade for 2013-Current 6.7L Cummins 2019 Is Necessary
I upgraded to the ATS Thermal Bypass Valve because I wanted better transmission protection and more consistent fluid temperatures in my 2013-current 6.7L Cummins. From my experience, the factory setup can let the transmission fluid stay too cold for too long, especially in colder weather or during short trips. That means my truck may not shift as smoothly as it should, and the transmission can take longer to reach the ideal operating range.
I also like that the ATS valve helps reduce unnecessary restriction in the cooler circuit once the transmission is warmed up. In my case, that gives me more confidence when I’m towing, hauling, or driving hard, because stable fluid temps are important for transmission life. When the transmission stays in a better temperature range, I feel like I’m doing more to protect expensive components from wear and stress.
Another reason I consider this upgrade necessary is peace of mind. My truck is a heavy-duty workhorse, and I want it to perform consistently whether I’m commuting, towing, or running in changing weather. The ATS Thermal Bypass Valve is a simple upgrade, but for me
