Michael, sounds like you're gettin' all confused here.
MT-90 is a GL-4 gear oil for manual transmissions.
You've been telling me/us all along that you have an automatic transmission
in your 91 GL vanagon.
It would take ATF Dexron in the auto trans part,
And GL-5 gear oil in the differential portion, which you can check or fill
by a plug on the side,
But you can't drain it without dropping the pan for the diff. portion.
Are we getting clear in any way yet ?

Just wanted to confirm...MT90 for 91 GL? Sells in town for 9.95QT. and
aftermarket 3pc gasket/filter kit is 9.95...Sound right?
  Thanks, Michael
