[W126 Coupe] Transmission problem

[Barry Sharp]

I've had a similar problem on a 300E and my 560SEC.  The cure in both cases
was to change the transmission fluid and filter.  The problem disappeared.
MB transmissions seem to be very sensitive to dirty fluid.

 

YMMV.

My 560 SEC is an 89 with 66,000 miles on it.  I've enjoyed the 1st gear
start kit for several years now.  The other day my transmission started
shifting down to second gear all on its own.  It happened at speeds of
around 45 to 50.  Then it would refuse to shift back to 3rd.  If I came to a
complete stop and started driving again it would go through the gears and
then shift down to 2nd again.

   

  Any suggestions??  Do you think it is electric or a vacuum problem?  Might
it be related to the 1st gear start module?

   

  Any help would be appreciated.
