Worth every penny!
by Cody
Install takes no time at all.
I had to move my camper right after putting it on (which weighs around 16,000 pounds), the transmission stayed much cooler than it would have with the factory bypass. I’ll replace the coupler next time I change fluid and filters, but anything beats the stock plastic one. This is the best kind of mod there is, inexpensive, easy to do, and works!
55 degrees cooler
by Dan
2022 Ram 2500 6.7 under normal everyday driving (not towing) the transmission temp would run 178 degrees. Installed the thermal Bypass and now 123 degrees is what I am seeing now. Great improvement.
Significant emperature drop after install
by Craig Dunning
2020 Ram 2500 6.7 Cummins. Prior to Thermal Bypass install, always ran 165-170 F degrees around town. After install and hauling 10k for 500 miles including hills, never exceeded 143 F.
