Transmission Cooling

Transmission Cooling








INTRODUCTION
The transmission cooler is integrated into the left hand end tank of the engine cooling radiator. The transmission fluid is cooled by the temperature differential between the transmission fluid and the engine coolant.

The fluid cooler is an aluminum cooler comprising louvred fins and plates. The plates allow a cross-flow of transmission fluid through the cooler. The fins are immersed in engine coolant on the 'cold' side of the radiator which provides cooling of the transmission fluid via heat transfer.

This fluid cooler design provides an advantage over an air-cooled cooler in that the fluid cooling is controlled with engine coolant temperature. Fluid temperature control is also improved when the vehicle is moving slowly or is stationary with the engine running.

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.
