[MBZ] OK, WTF? The pepto is back

[Kaleb C. Striplin]

OK, y'all remember the saga of the pepto in the tranny of my 190D. 
Swapped the radiator out, got all the junk cleaned out and tranny fluid 
looks fine.  Drove it for about 3 weeks and no more pepto.  Car has been 
sitting for about 3 weeks or so and I just now checked today and its 
full of pepto again.  Before I was loosing some coolant but this time, 
the coolant is just fine, have not lost any.  The only thing I can come 
up with is that we have had lots of rain the last couple of weeks. Is 
there some way that rain water can get into the tranny while the car is 
just sitting?  This one has me stumped!!  Maybe my first radiator wasnt 
bad after all.  Is there anyway I can check a radiator while its out of 
the car to see if its leaking fluid into the tranny cooler portion of it?
