The thermal bypass valve is used in transmission cooling & heating systems. It regulates oil flow and flow direction in order to self-control the operating temperature of the transmission. OEMs use the TBV to retain oil in the transmission in cold weather, thereby heating the oil quickly and reducing internal friction. This feature reduces fuel consumption significantly in cold weather. In hot weather the valve allows oil to flow to the vehicle auxiliary oil cooler for maximum cooling performance.
