My understanding is that the fluid level should be at or near the top mark when the fluid is at full operating temperature. Make sure to measure with the car idling on a level surface and in 'D' (and parking brake engaged). I've heard that some people try to feed a thermocouple down the dipstick tube, but measuring the pan temperature from underneath works better.

You used the special MB synthetic ATF (AKA Febi synthetic Dexron III), correct?
