The reason I’m asking is this- the transmission has been acting a bit “strange” for the past couple of days so I jacked the car up to check the level. When engine is off the reservoir is full to the rim, when I first start and run it through the gears it’s right at the max level. What got me worried is that once the car reaches normal operating temperature it goes above max. I do recall filling it to between the min and max level when I replaced cooler lines a while back, I wonder if I messed it up somehow…

From your description. It sounds like it may be overfilled. There are three marks on my 84S resovoir. Very bottom is max. full with trans cool. second mark is min. with trans warm. Top mark is Max. with trans hot. Of course this is with motor running in neutral, level surface.I think it is most accurate to take reading with trans cool. By cool I mean ambient temp 80ish F. When engine is off, and trans cool, and fluid drains back into resovoir, my level reads just above the upper Max mark to keep it from overflowing out of resovoir cap vent / tube
Now there, isnt that clear as mud ??

That is where I would start. Drain some out then start fresh. Then after things are nice and HOT, check to see where level is relative to HOT Max. mark. These Mercedes trans. are very sensitive to proper fluid levels. Good luck with it. Kevin

The 20c mark is used when you're working on the car at ambient temperature (Just did my filter/fluid). Where most of us do these things to avoid the "boiling in oil over the castle wall effect" when you miss the collection pan/tray/tank........So....if you're not fresh in off of a highway run, and the entire car is thoroughly up to temperature, ignore the Max. Mark. If it's good and warm, the minimum mark would apply.
