Hello list,
 Just refilled the trans on my syncro, it took about 4
1/2 qts. I don't know for sure, but I'd say stick with
the GL-4 for any transmission. I think the
conventional wisdom got muddled up somewhere; GL-5
will eat up the SYNCHROs (syncroniser rings), and I'm
fairly sure they are the same composition in all
Vanagon trannys. Look for "MTL" on the bottle, and
check twice, I had to return 2 bottles, they look
identical. The liquid is bright red, low odor for the
GL-4, and pale orange and stinky for the GL-5.

I think the general consensus is MT90 for warmer
climes, MTL for colder
climes.  Both meet the specs for your tranny (80
weight).  The 75W90 is
GL5,
and should only be used in the front diff on a syncro,
so watch out for
that
one.
