Mishimoto MMTC-RPTR-TBVFF 10R80 Full-Flow Thermal Bypass Valve for 2017-2020 Ford F-150 (3.5L)

Fits 2017-2020 Ford F-150 (3.5L) models equipped with the 10R80 transmission.

The factory thermal bypass valve in the 10R80 transmission is a common failure point that can restrict or completely block fluid flow to the external cooler. When this valve fails, it leads to rapid overheating, transmission fluid degradation, and potential internal component damage. The Mishimoto MMTC-RPTR-TBVFF thermal bypass valve upgrade replaces the stock thermostat with a full-flow design, ensuring constant cooling from the moment the engine is started.

Constructed from CNC-machined aluminum for long-term durability, this direct-fit upgrade is ideal for vehicles operating in hot climates, heavy towing applications, or demanding off-road conditions. By maintaining a constant flow to the transmission cooler, it eliminates the risk of a malfunctioning internal thermostat. Installation is straightforward and typically takes approximately one hour using standard hand tools.

• Full-flow design ensures maximum transmission cooling efficiency
