Help with identifying a part.

Hey guys, I've tried looking at multiple part diagrams online but having difficulty trying to ID what this part is on the underside of engine.

So I know that I've got an upper coolant bypass leak, but fortunately its been a very slow leak, I've been keeping an eye on it very carefully.

However I climbed down under the truck the other day to re-tighten some cats shields and noticed that this part is now covered in a film of dried coolant (which it was not last I checked)
I am curious what this part is as it has hoses coming to-from but it seems like a transmission related part?

I am just trying to rule out that coolant is not seeping out of the hoses on this chingadera, and its possible its just the upper coolant hose leak working its way down.
