The transmission fluid cooler is located on the left radiator end tank. The cooler bracket has two lugs which locate in corresponding lugs on the end tank. The cooler is positively located by a self tapping screw at the top of the bracket. The fluid cooler is an aluminum housing comprising louvred fins and plates. The plates allow a cross-flow of transmission fluid and engine coolant through the cooler.
The plates are immersed in engine coolant from the 'cold' side of the radiator which provides cooling of the transmission fluid by the temperature differential between the transmission fluid and the engine coolant. The transmission fluid cooler receives engine coolant from the low temperature zone at the top third of the radiator. The engine coolant flow through this section of the radiator is restricted by the transmission fluid cooler. Therefore the engine coolant has a slower flow rate across the cooling tubes of this section of the radiator. This cools the engine coolant more than the lower part of the radiator and consequently provides increased cooling of the transmission fluid. The coolant then passes from the fluid cooler into the radiator bottom hose.
Two quick release connectors on the cooler provide for the attachment of the transmission fluid pipes to and from the transmission. Fluid is supplied from the transmission fluid pump into the lower connection of the cooler. After passing through the cooler, the fluid passes out of the upper connection and is returned to transmission fluid pan.
In hot climate markets an additional transmission fluid to air cooler is located at the front the radiator.
