What is the metal tube that connects to lower hose on a dodge caravan 2006 v6 3.3?

That metal tube connecting the lower radiator hose on a 2006 Dodge Caravan 3.3L V6 is most likely the transmission cooler line. There are usually two, one going to and one returning from the transmission. They're part of the transmission's cooling system, routing coolant from the engine's cooling system through the transmission to help keep it cool.
