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

Description

The Mishimoto MMTC-JK-TBVFF full-flow transmission thermal bypass valve kit is designed specifically for the 2012-2018 Jeep Wrangler JK, offering a reliable upgrade to your vehicle’s cooling system. This all-aluminum CNC-machined housing replaces the stock bypass valve, eliminating a common failure point and ensuring consistent transmission fluid flow. The full-flow design allows the transmission fluid to circulate through the cooler immediately upon startup, which is especially beneficial in hot climates or under demanding driving conditions such as towing or off-roading. Maintaining optimal transmission temperature is critical to prolonging the lifespan of your drivetrain and ensuring smooth operation.
The original thermostatic bypass valve in your Jeep is intended to prevent overcooling in cold environments by restricting fluid flow through the cooler until the transmission reaches a certain temperature. However, if this valve fails, it can lead to overheating, risking significant damage and costly repairs. The Mishimoto upgrade removes this risk by providing a direct path for fluid to flow through the cooler from the moment you start your vehicle. This proactive approach enhances cooling efficiency and helps prevent overheating during extreme driving conditions.
Installation is straightforward, typically taking less than an hour, and requires no specialized tools. Made with durable aluminum, this kit is built to withstand harsh conditions and is backed by Mishimoto’s signature lifetime warranty, ensuring long-term reliability. Whether you’re driving in hot climates, towing heavy loads, or simply seeking peace of mind, this full-flow bypass valve kit offers a robust solution for maintaining your Jeep’s transmission health and performance.
