*****transfer case vent is in place and a separate hose
Expert:  Dave Nova replied 1 year ago.
You are correct. It is a separate hose. Trans vent hose does not connect to anything at lower end. It is secured in a clip (see attached picture) near drivers side of crossmember near the frame.

Hose number 4 in the picture is what I am talking about so it open at the frame where it clips in
Expert:  Dave Nova replied 1 year ago.
Yes, hose #4 is open at the bottom. It is secured in clip #8. It is left open so if that if fluid were to come out of the vent, it could drain from the hose, away from the engine and hot exhaust components.
