Some cars do use motor oil in the transmission/differential.
I had a 77 Honda Civic that called for 10-30 oil in the
trans. I put some syntheticc oil in hoping to reduce wear, etc.
The transmission became hard to shift and the gears would grind,
especially between first and second. I put standard 10-30
back in and the problem went away. Turns out some friction is
required to make the synchro rings work properly. The synthetic
oil reduced friction to a point where the rings did not work.
