Mishimoto Full-Flow Transmission Thermal Bypass Valve Kit for Jeep Wrangler 2012-2018 - Part MMTC-JK-TBVFF

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. Automatic transmission oil cooler designed to regulate fluid temperature and prevent overheating. Enhances transmission longevity, maintains performance, and features durable construction with a precise fit.

• Direct-fit for 2012-2018 Jeep Wrangler JK

Proper temperature regulation is essential for maintaining transmission longevity, optimal performance, and reliable operation, especially under demanding conditions such as towing or off-road driving. The easy installation process takes less than an hour, making it a practical upgrade for Jeep enthusiasts seeking enhanced cooling efficiency. Built with durable materials and precision engineering, this kit offers a secure fit and long-lasting performance, backed by Mishimoto's signature lifetime warranty.
