On my 90, the gear oil drain plug is directly underneath the tranny and
the fill hole is at the end of tranny on a vertical plane. They both use a
allen to open up.
One thing I have notice in my car is when my starter went out the
symptom was that periodically it would not dis-engage and would
cause a huge grinding noise from the bell housing. Given that you
are complaining about grinding on dwonshifts most probably this is not
related. Just an FYI....
