Front Auto Hubs???

Well, ATF is not the only recommended oil for the TC, by Nissan's standards. I interpret this recommendation like this:
If you have an AUTO, then use ATF on the TC just in case seals fail between the AT and the TC, no harm is done.
If you have a MANUAL, then use the GL4 stuff the same as the MT, so if seals fail, again, no harm is done.

If the GL4 stuff (90w75, etc) is too thick for your location temperatures, then it may cause this that we are talking about. Just change to a thinner oil on the list (as long as it is GL4) and retry.

My '94 manual GQ Transfer Case is listed to use ATF.

I had issues with crunching into gear when cold in a partially rebuilt gearbox. The mechanic that had fitted it for me, had added 5GL oil and his advice was to add a bit of ATF that will help with smooth cold changes. But being a new member of this forum, at the time, the advice from a member, to drain the gearbox oil and refill it with GL4 made all the difference. Another older mechanic had also suggested adding a bit of ATF as well. From this I have come to the conclusion that gearbox oil diluted ATF isn't so bad. But on saying that, there are numerous brass components in the Nissan manual boxes that might eventually be eroded by ATF.
