Mishimoto MMTC-GMP-TBVFF Transmission Coolers

The transmission in your 2012-2021 Dodge Charger, Challenger, or Chrysler 300 is the heart of its drivetrain. Whether you're hauling groceries or knocking out highway miles, it's vital to keep it performing at its best, and keeping the transmission fluid cool is crucial to that goal.

In an attempt to balance drivability and the health of your transmission, Dodge/Chrysler fitted a thermostatic bypass valve to the lines that feed the transmission cooler. This valve ensures fluid doesn't flow through the cooler before the transmission reaches operating temperature, preventing overcooling in cold environments. However, when the thermostat in this valve fails, it's almost a guarantee your transmission will overheat. Moreover, those who live in hot climates will likely never have to worry about overcooling, rendering the valve a useless flow restriction.

That's why Mishimoto has developed a full-flow thermostatic bypass valve for the 2012-2021 Dodge Charger, Challenger, or Chrysler 300. The Mishimoto thermal bypass valve kit includes an all-aluminum CNC-machined housing that replaces the stock unit. This full-flow valve allows fluid to pump through the cooler as soon as the vehicle is started, eliminating the potential failure point of the stock bypass and providing cooling benefits. The full-flow design is beneficial to vehicles operating in hot climates, extreme driving conditions, or towing heavy loads. As with Mishimoto products, this Full-Flow Transmission Thermal Bypass Valve Kit includes our signature Lifetime Warranty.
