160 Degree Transmission Thermostat and Bypass Valve Kit 2005-2023 HEMI 3.6L / 5.7L / 6.4L by Mishimoto

Mishimoto has identified a common failure point in the transmission cooling system of your  Mopar: the thermal bypass valve. This component acts as a thermostat, restricting fluid flow to the external transmission cooler based on temperature. Unfortunately, many vehicle owners have found these factory units are prone to failure, often sticking in the closed position resulting in an overheating transmission. The engineering team at Mishimoto has created a high-quality thermal bypass replacement with numerous additional features to ensure consistent performance and long transmission life. This unit is constructed from durable CNC-machined billet aluminum, featuring a heat sink design that provides improved heat dissipation and unique styling. The included thermostat opens at a temperature of 160°F (71°C) but can be customized to suit your needs with any available Mishimoto thermostat. The Mishimoto thermal bypass kit also includes a bypass that can replace the thermostat, allowing constant fluid flow to the transmission cooler. The bypass is ideal for vehicles requiring maximum cooling while operating in extreme driving conditions or hot climates. This kit easily installs within one hour and connects directly to all factory cooler piping.
