Do you mean AMC 20 or Dana 30? Either way, standard 80W90 should work OK
Pennzoil Syncromesh. The NVG trannies use a very specific type of fluid. If you want to get reamed you can go to a GM or Chrysler dealer for it.
Not sure which vehicle you have, but if it's an AMC axle it's likely a CJ. The Chilton guide for CJs 76-86 states that the transfer case and transmission on CJs are linked and share fluids, although it is necessary to drain both reservoirs separately when doing a change to ensure everything drains completely. Whatever fluid you select, you better be sure you use the same thing on both and change it all at once!
The model is irrelevent, as is the manual for that model, since he stated he has a sDynatrac Dana 60 and NVG4500 tranny, neither of which were ever available from factory in a Jeep. More than likely he has a Dana 30 front and Dynatrac 60 rear...if he had an AMC20 rear it's highly unlikely he would put a stronger axle in front. But not impossible.
But they didn't source their axles from Dynatrac, since ABS wasn't around in '72 except possibly in jet planes, (wink) and the front axle would probably have been a 44 at least.
Your Chilton guide is just plain wrong Joshua.
The T-case and tranny do not share anything, let alone fluids.
I have an 86 and my tranny and t-case need different fluids.
They have an air gap in-between them and each has their own seal.
They also only put a high water vent on the t-case. There is no high water vent on the tranny so you can fill the tranny full of water and only have to change it's fluids, the t-case will still be fine.
