The transmission in your Jeep Wrangler is the heart of its drivetrain.
It's vital to keep it performing at its best, and keeping the transmission fluid cool is crucial to that goal.
Jeep fitted a thermostatic bypass valve to the lines that feed the transmission cooler in an attempt to balance drivability and the health of your transmission.
This valve prevents fluid from flowing through the cooler before the transmission reaches operating temperature, avoiding overcooling in cold environments.
However, when the thermostat in this valve fails, your transmission will almost certainly 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 2012-2018 Jeep Wrangler.
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.
This Full-Flow Transmission Thermal Bypass Valve Kit includes our signature Lifetime Warranty, as with all Mishimoto products.
