What wt of transmission oil for D6 9U?

I'm confused about what the manual says for the wt of the transmission oil. It looks to me like like it says 30 wt but that seems pretty light. Maybe I'm not reading it correctly. Right below the 30 wt it says 80 & 90 wt but that appears to be referring to the final drives. Can someone straighten me out on this? Thanks.

It's normally 90wt in the transmission/bevel gear case and finals unless running in extremely hot temperature then 140wt. For below freezing the recommendation is 80wt.
