Replace the problematic factory thermal bypass valve in your 2013-2018 Dodge Ram 6.7L Diesel before it causes catastrophic failure with the XDP Xtra Cool Transmission Cooler Thermal Bypass Valve Upgrade XD343. The OE thermal bypass valve is designed to route bypass the transmission cooler in cold temperatures in order to bring the transmission up to operating temperature faster. Unfortunately, the bimetallic valve commonly fails in the closed position, causing hot transmission fluid to constantly circulate right back into the transmission, never, or barely, passing through the cooler at all. This results in excessive transmission temperatures, potentially damaging your transmission and leaving you stranded on the side of the road with not only an expensive tow bill, but a costly repair bill as well!
