I haven't crawled under my truck yet because I haven't changed the oil yet (about to change within a month or two) so I don't know what's under there yet. Rockcrawler could probably give you a good answer on this though.
My guess, based on the look of it, and where it's placed and what you said...probably the drain bolt for the transmission? I would think that if it is that, it should not be loose....
