The Mishimoto full-flow thermal bypass valve for 2013–2018 Dodge Ram 6.7L Cummins replaces the failure-prone stock thermostat valve to ensure continuous fluid flow to the transmission cooler. CNC-machined from aluminum with machined flow passages and cooling fins, it eliminates the internal thermostat and improves cooling under heavy towing or warm climates. It installs in under an hour and carries Mishimoto's finish and warranty.
