My 91 300 SL which I bought 6 weeks ago came with a late and hard 1-2 shift.  
When it is cold the shift is very late and very violent.  When warm it is 
slightly better. It definitely is not right.  All other shifts are PERFECT.  I 
really love how it shifts and revs.  Really a blast to drive.  I have driven MB 
for 25 years and this is really bad.   I know how they can shift a little hard 
when cold but this is VIOLENT.  

Took it to a very good tranmission guy here in PA that I have used before and 
he found and repaired the valve body gasket which was "blown" out.  The 
repair did NOT fix the shift at all.  I called the shop forman for my local MB 
dealer and he confered with his mechanics and they suspect that the B1 servo valve 
is sticking and hanging up the first gear band.

Anyone else had and FIXED this same problem ???

Thanks in advance for any help.
