The Automatic Transmission Fluid (ATF) cooler is attached to the engine cooling radiator with a mounting bracket. The ATF cooler has 2 lugs which locate in corresponding lugs on the mounting bracket and secured with a screw. The ATF cooler is an aluminum housing comprising louvred fins and plates. The plates allow a crossflow of ATF and engine coolant through the ATF cooler. The plates are immersed in engine coolant from the cold side of the radiator. This provides cooling of the ATF by the temperature differential between the ATF and the engine coolant.

The ATF cooler receives coolant from the sub cooled portion of the main radiator and from the left auxiliary radiator. The engine coolant flow through this section of the radiator is restricted by the ATF cooler.

The engine coolant then passes from the ATF cooler to the thermostat housing.

The use of the subcooled radiator and the left auxiliary radiator cools the ATF more for the high performance application.

The 2 quick release connectors on the ATF cooler provide for the attachment of the ATF hoses to and from the automatic transmission.
