It ONLY pertains to the old gear driven transfer cases and transmissions. The newer designs like you mention generally use comparably light weight lubricants.
Here's a post by Eldon McFarling, a well respected IH/diesel enthusiast on the matter. It's in the FAQ on the OldIHC site.

This quote is taken from that post:
>>>
For manual transmissions, and transfer cases:
Dana / Spicer, New Process, Warner, IH T-34,T- 35, & T-36
Specially formulated SAE 50 transmission oil
