Mr. Ditmire I have a '98 C230 sedan that I bought new and have had serviced
regularly at my selling dealer. It has 91,000 miles on it now.
This car has an electronically shifted transmission. Since my second year
of ownership it has had a problem on cold starts with holding on to low gear
and delaying upshifting.
The dealer has looked on four separate occasions for a cause, and each time
reported back that they've installed the latest software upgrades and they
can find nothing else wrong with it. I've also gotten a lecture about how
it has a "driver adaptive transmission" (whatever that means) and that they
behave differently than the ordinary mechanical/hydraulic transmissions I'm
used to - to which all I've done is roll my eyes and say "Oh".
The thing got real bad a few weeks ago and although I don't usually drive it
myself, I had to go somewhere the other day and so I got in and cranked it
up and went off down the street. This time it not only delayed the shift
overly long --- it NEVER SHIFTED! It hit the rev-limiter.
Of course the car is long since beyond warranty, but this just seems like
the end result of an on-going process that started way back a long time ago
when the vehicle WAS covered.
The car sits today in a service bay at my local dealership. After several
days tinkering they have concluded that there is indeed something internally
wrong with the trans. We've had several discussions during the past few
days after they first offered to swap it out for me and all it would cost
would be about $4K.
Are you aware of any particular problems with C230 transmissions?
Anything you or other knowledgeable parties could contribute would be
Thx in advance.
