   I've observed the same, years ago and, IMO, it is right to fill thru
the diff. hole to it's level. As I saw on a drawing in a Shop Manual
(don't remember which one) when the ring rotates send oil to the
transmission (by the upper hole) increasing it's oil level. The oil
returns to the diff. by the lower common hole by gravity (at lower rate ?)
keeping both transmission & diff. At similar levels. At high speeds it is
possible to have transmission oil level higher than it's "filling" hole
while lower at lower speeds or stopped. Just my toughts about.
