Mishimoto 2012-2019 Dodge V6 8HP Transmission Thermal Bypass Valve Kit

The factory thermal bypass valve in your 2012-2021 Chrysler 300 (and other Mopar V6 models) can be a weak point, often failing in the closed position and leading to transmission overheating. Mishimoto has developed a replacement that addresses this common issue. This kit is constructed from CNC-machined billet aluminum, featuring a heat sink design that helps dissipate heat and offers a unique look under the hood.

This thermal bypass valve opens at the stock 160°F (71°C) temperature, ensuring your transmission warms up properly in colder climates. For those in hotter regions or who push their vehicles hard, the kit includes a bypass plug that replaces the thermostat, allowing for constant fluid flow to the transmission cooler. This provides maximum cooling when you need it most. The kit is designed to connect directly to all factory cooler piping, making installation straightforward and typically taking about an hour.
