The Automatic Transmission Fluid (ATF) warming valve is a thermostatic ATF mixing valve. It is designed to reduce ATF warm up time and provides a precise temperature control for the ATF temperature. The ATF warming valve mixes the hot engine coolant from the thermostatic valve and cold engine coolant from the low temperature zone at the left side of the radiator. This provides the desired temperature control of the ATF temperature.
