Power By The Hour 6R80 Thermal Bypass Valve (2011–2017 Mustang & F-150 6R80) ACC-1149

Restore Proper Transmission Cooler Operation

The Power By The Hour 6R80 Thermal Bypass Valve is a direct replacement solution designed for Ford's popular 6R80 automatic transmission. This internal thermal bypass valve plays a critical role in regulating transmission fluid flow, helping the transmission reach operating temperature quickly while ensuring proper cooling once optimal temperatures are achieved.

How the 6R80 Thermal Bypass Works

Similar to an engine thermostat, the factory thermal bypass remains closed during cold starts, limiting fluid flow through the transmission coolers to help the transmission warm up efficiently. Once operating temperature is reached, the valve opens and allows transmission fluid to circulate through the cooling system before returning to the transmission.

Critical for Transmission Swaps

This valve is especially important for enthusiasts utilizing 2015–2017 F-150 Gen 2 6R80 transmissions in Coyote swaps or other custom applications. Unlike Mustang models, these transmissions utilize an external bypass cooler assembly from the factory. Since the external unit is commonly eliminated during swap installations, installing this thermal bypass valve helps ensure the transmission continues to function as intended.

Ideal for Performance Builds

Whether you're performing a Coyote swap, building a high-performance 6R80, or replacing a worn factory component, this valve helps maintain proper transmission temperature management and fluid circulation for improved reliability and longevity.

Key Features

• Direct replacement thermal bypass valve for 6R80 transmissions
• Regulates transmission fluid flow through cooling system
• Promotes proper transmission warm-up and cooling operation
• Essential for many Gen 2 F-150 6R80 swap applications
• Supports proper transmission function when external bypass systems are removed
• Ideal for performance and custom transmission builds
• Helps maintain transmission reliability and longevity

Why You Need It

When installing a Gen 2 F-150 6R80 transmission into a swap vehicle, the factory external thermal bypass assembly is often omitted. Without a proper bypass solution, transmission fluid flow and temperature management can be compromised. The PBH Thermal Bypass Valve restores the intended operation of the transmission cooling circuit.
