hello, just picked up a 1971 250 automatic. manual says it is a 4 speed, when i come from a stop i count 4 gears, but 65 mph seems at high RPM's. shifting is roughly as follows
approx 1/5 throttle.
shifts into second around 4MPH
shifts into third around 20MPH
shifts into fourth around 25-28MPH.

anyone have same model that can give some input? or any input from knowledgeable Mercedes fanatics.

Thanks,
Donny
