2009-2018 Ram 1500 5.7L Hemi Thermal Bypass Valves

The stock thermostatic valve is a critical part of your 2009-2018 Ram 5.7L Hemi's transmission cooling system. Unfortunately, it's also notoriously unreliable and can get stuck closed, which prevents transmission fluid from flowing from the transmission to your Ram's transmission cooler. Tier One's selection of Ram 5.7L Hemi thermal bypass valves delete the stock thermostatic element of the OEM valve, giving your Ram more reliable operation and lower transmission temperatures. These Ram Hemi transmission thermal bypass valves and delete plates are extremely easy to install, making them a must-have for practically any Ram 5.7L Cummins build.
