An external oil-to-air type automatic transmission oil cooler is mounted to the front of the radiator and is integral to the A/C condenser. The six upper tubes are used for transaxle oil cooling, and the remaining tubes below are for the A/C system.

The cooler uses tubes and rubber hoses to feed oil to and from the automatic transaxle. The replaceable inlet and outlet tubes use quick-connect type fittings. The trans oil cooler is replaced with the A/C condenser.

Operation

The oil flows from the transmission to the oil-to-air cooler. Heat is then transferred into the air.
