A quick BITOG search hasn't shown much info on the Ford power transfer units (PTU) found in various AWD Ford applications. I browsed through the most recent thread (~Spring 2016) and didn't see this posted so I figured it'd be worth mentioning and discussing.
Here's an interesting link I found. Blackstone recomended 10k intervals on a PTU with the factory cooler. Explorer Forum
Keep in mind, this is on an Explorer. I am not sure if there's any differences between these and other AWD Fords. Tauruses, (as well as the SHO), Fusions, Edges etc.
Some PTU's have coolers while some do not. Also, at least on the older models for the North American market, there's plenty of how-to's on adding a drain plug because originally Ford thought it was a lifetime fluid. Simple Googling has shown many failures well under 100k. They get hot and when they're by the exhaust, I imagine they get even hotter.
