Product Details

The Mishimoto MMTC-JK-TBV Thermal Bypass Valve Kit is an upgraded transmission cooling solution designed specifically for 2012-2018 Jeep Wrangler JK models. This direct-fit replacement improves upon the factory bypass valve with increased flow capacity and enhanced thermal management capabilities.

Key Features:

  • CNC-machined billet aluminum construction for maximum durability
  • Integrated cooling fins machined into the body for improved heat dissipation
  • Increased flow capacity compared to factory bypass valve
  • Includes 160°F thermostat to match OEM valve opening temperature
  • Fully serviceable thermostat design allows customization with optional Mishimoto thermostats
  • Durable anodized finish resists corrosion and wear
  • Direct-fit installation in under 1 hour with no modifications required
  • Thermostat bypass capability for constant cooling in extreme heat conditions

This thermal bypass valve kit provides precise control over transmission fluid temperature, ensuring faster warm-up in cold weather while preventing overheating during demanding driving conditions. The serviceable design allows you to fine-tune the opening temperature by swapping thermostats, making it adaptable to any climate. Backed by the Mishimoto Lifetime Warranty for worry-free performance.
