Does tranny & TC have vents?

May sound like a stupid question but since I've never had either out of the truck.........? Does the transfer case or 4 speed tranny have vents for them? Like the front and rear differentials. And if they do, can anyone tell me where to find them and if they are able to be reached?

Changed fluids for both about 4 months ago........the TC looks just like when I put it in, honey colored........the tranny fluid looks much darker so I was wondering if a missing vent might be contaminating it. Used same 80W-90 Valvoline syn blend in both. Any help appreciated.
Thanks.

Yep, they both do. I posted a pic in the 4x4 forum of the vents on my tranny and t-case.
