As far as MB approvals go...Shell 3353 (DHS Gremany) or Fuchs 3353. Unless you go to the newer fluid 4134 or 134, again only Fuchs OR Shell from Germany.

Why damage a $4000 trans by saving $50??

Out of curiosity, as a dealer tech who no doubt sees many 722.6 transmissions, have you personally seen one damaged by using any of these specific fluids?
