Hi. it seems to me that the fluid was over filled when I had
a look after the problem started. got the car, drove
down from SJ to LA and then on the way back this problem
developed. car only has 60k.
in LA the surging forward was barely noticeable, and by
the time we got back, it wasn't that tolerable when you're stopped
at a intersection. also a couple times along the way
it wouldn't go into gear until revved high.

i've taken apart the valve body in order to examine the b2 piston,
and it seems pretty clean, fluid was pretty clean....
then again, I'm a newbie as far as auto transmissions and
Mercedes go.....
