What is the Small Line on the 4L60E?
I have a 4L60E I'm swapping into my 6 speed T/A. Everything is done now except there is a smaller 3rd line (smaller than the 2 cooling lines) going back toward the engine. It was cut off by whoever pulled the trans so I can't tell how far it is supposed to lead. What is that little line and where does it go?

I figured it was either a vent or some kind of overflow. It just seemed a bit long and soft just to be a vent to me. Does it actually plug in anywhere or is it cool just being open under the car like that?

This is a soft rubber hose that's over 3 ft. long, hooks up into the tranny (on top I think), and is open on the other end. Is the vent tube the same thing as the overflow line because I think that's what this is. If so, all I have to do is route it away from the exhaust and hot engine parts, leave it open on the end, and its all good?
