I doubt if the 2 oils would separate once mixed, since they are both petroleum 
based oils to start with. I agree with your conclusions above and would have to 
say that this looks pretty normal and healthy.

I SUSPECT that problems with the seal between the AT and the final drive are 
rare, just because this seal has oil on both sides of it. Thus there's no place 
for rust to start, so you can't get a rusty surface to abrade away a seal and 
wear it out. A seal will last almost forever if there is no rust or dirt 
present, if it is always lubricated, and if the sealing surface is smooth.

The seals that give us problems are those which are exposed to the outside 
world on one side. Unfortunately, this is the most common situation.
