Since the transmission only uses about 3 quarts of oil, you may want to
consider a synthetic such as Mobil1 15-50 or Amzoil 20-50. I use the
Mobil1 15-50 in both the engine and transmission of my MGC. It flows
better at lower temperature than 5w30, but has superior high temperature
specs. In the transmission I think it makes econimical sense, as its not
changed often. In the engine it depends on how much you leak or burn. One
advantage I find is that you can leave the same weight oil in year round so
your not caught with heavey oil if you want to crank your car up during a
cold winter day.
Mobil along with most oil companies has web pages providing specs, cant
find address but a net search should find it easily.
