No, for cooling.

Correct. In your radiator there is another small "radiator" only for the transmission fluid. The hydraulic fluid is separate from the coolant. Instead of having a separate radiator for cooling the hydraulic fluid they incorporated it in the coolant radiator. It is a method for cooling both system used to this day.
