What is latest specs for atf for 450sl 1977 manual calls for dextron II. What is current replacement that will work? Thanks, Abe G

Dextron II was replaced by III. There are 12 "approved" ATFs, 3 of the most common are Quaker State, Pennzoil, Castrol. If want the whole list you can contact MB and they will send you a copy of the "Approved Service Products List". This booklet won't necessarily list your exact model but it list the approved fluids for MB cars.
