Transmission oil cooling, general
Transmission oil cooling lowers the temperature of the transmission oil and thus prevents overheating damage in the transmission.

Function sequence of transmission oil cooling
The transmission oil is drawn out of the transmission oil pan by a mechanical pump in the transmission and pumped via the feed to the transmission cooler (which is integrated in the engine radiator). The transmission oil then flows through the return line back to the transmission.
