Need a little help...

I've got Automatic Transmission fluid in the transfer case of my 71 Jimmy (It's been in there since I bought it and I've never changed it). If I remember right my old 72 Blazer had 80W-90 in the transfer case and the Haynes manual I have for 67-87 truck says that 67-80 vehicles get 80W-90 in the transfer case.

I've got 2 ?'s:
What kind of tranfer case do I have (NP203,205?)or other? The front driveshaft goes forward on the passenger side if that helps identify it...

I've taken this truck on several long trips (Four 7-8 hour trips) and never had any problems. Keep the cherry juice or switch? is it the right fluid for my transfer case.

Just want to do a little preventive maint. and change the fluid.
