Coolant leak

So I'm thinking it's just this top fitting. Anyone else have an idea?

Sure looks like it, have you tried tightening it a bit?

And that's not a coolant leak, I beleive that's transmission fluid at that point.

Have you figured out what you are leaking, tranny or coolant? that would help pin down where it is coming from. Also, have you found where it's coming from any drip marks on the chassis or something?
