More than likely this is a transmission line or the cooler itself. The transmission cooler is located by the radiator so that it can have access to the air in the front of the vehicle so it can cool the transmission oil.
Best thing to do is clean the under-body off and then add a dye to the oil to see where it is coming from.
Let me know what you find.
