The Automatic Transmission Fluid (ATF) cooler locates at the front right of the automatic transmission with 3 bolts. The ATF cooler has 3 lugs which locate in corresponding lugs on the transmission main casing and secure with a screw. The ATF cooler is an aluminum housing comprising louvred fins and plates. The plates allow a cross-flow of ATF and engine coolant through the ATF cooler. The ATF and engine coolant do not mix in the ATF cooler.
The plates are immersed in engine coolant from the ATF warming valve. This provides cooling of the ATF by the temperature differential between the ATF and the engine coolant.
The ATF cooler has an integral thermostatic valve, which controls the ATF flow through the cooler. Flow is restricted to improve ATF warm-up time. The thermostatic valve is closed at temperatures of 78°C (172°F) and below, starts to open at temperatures of between 78°C and 84°C (172°F and 183°F). The thermostatic valve is fully open at temperatures of 96°C (204°F) and higher.
