Mishimoto Transmission Thermal Bypass Valve Kit for Jeep Wrangler JK

The transmission is a critical component of your 2012-2018 Jeep Wrangler JK's drivetrain. To ensure optimal performance and longevity, maintaining proper transmission fluid temperature is essential. Mishimoto's performance thermal bypass valve upgrade directly addresses a common failure point in the factory system, preventing potential overheating issues.

Reliable Temperature Regulation

Jeep equipped the JK Wrangler with a thermostatic bypass valve to regulate transmission fluid temperature, preventing overcooling in cold climates. However, the thermostat within this valve is prone to failure, often sticking in the closed position. This failure restricts fluid flow to the transmission cooler, leading to dangerous overheating, especially in warmer weather or during demanding off-road conditions. Mishimoto's replacement valve ensures consistent and reliable operation.

Engineered for the Trail and Beyond:

• Direct-fit replacement for the stock thermal bypass valve on 2012-2018 Jeep Wrangler JK models.
• Robust construction designed to withstand demanding driving conditions.
• Ensures proper fluid flow to the transmission cooler when needed.
• Prevents transmission overheating caused by faulty factory thermostats.
• Helps maintain optimal transmission fluid temperatures for improved performance and durability.
