I contacted MB of Gainesville today. The service department advised me they could not give me the information as I am not supposed to service the transmission. I became a little testy at which time they agreed to give me the information stating it was 11-12 quarts. When I advised them that was impossible they rechecked and stated 11-12 quarts.....Its quite obvious their intention was for me to damage my transmission. I contacted MBUSA customer service and advised them what had happened, they advised they could not be responsible for what was told to me by a dealer...The bottom line I was advised my 722.6 takes 7.5 litres when totally drained......
