DESCRIPTION

The transmission in your Jeep Wrangler is the heart of its drivetrain. Whether you're hauling groceries or hitting the trail, 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, Jeep 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 2012-2018 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. As with all Mishimoto products, this Full-Flow Transmission Thermal Bypass Valve Kit includes our signature Lifetime Warranty.

NOTES

  • This performance thermostatic bypass valve only fits vehicles with 5-speed automatic transmissions
  • Mishimoto does not recommend customers in cold climates install the thermostat bypass to avoid overcooling of the transmission fluid

Thermal Bypass Valves 101 – What are they and How do they Work

October 19, 2021

The sturdy gear sets housed inside, transferring power from the engine, are the gatekeeper to hauling heavy payloads, traversing treacherous rock gardens, or setting blistering lap times. No matter how powerful your engine is, without the transmission, your vehicle is dead … Continue reading Thermal Bypass Valves 101 – What are they and How do they Work →
