Protect your drivetrain with the Mishimoto Full-Flow Transmission Thermal Bypass Valve Upgrade. Factory transmission cooling systems often utilize a thermostatic bypass valve designed to restrict fluid flow to the cooler until operating temperatures are reached. While intended to prevent overcooling, these OEM valves are a notorious failure point; a stuck thermostat can quickly lead to catastrophic transmission overheating. This Mishimoto upgrade replaces the restrictive factory unit with a CNC-machined, all-aluminum full-flow housing.

By allowing transmission fluid to circulate through the cooler immediately upon startup, this kit eliminates the risk of thermostat failure and provides maximum cooling efficiency. This is an essential upgrade for vehicles operating in hot climates, those used for heavy towing, or Jeeps tackling demanding off-road trails. The kit is designed for a direct-fit installation, typically completed in under an hour using basic hand tools.
