Hi all,


I recently started using my 1990 Mercedes Benz 300E w/89K. I
purchased it 7 years ago because it was in mint shape and was a good deal.
The car had basically been in storage for the last 7 years. I used it for
an average 100 miles per year bring it in and out of the garage a only few
times a year. I changed the oil yearly and kept the gas fresh too. It was in mint shape when I bought it.....the previous owner was very meticulous.


The car ran great for about 2 thousand miles but last week I noticed
the transmission is occasionally revving before shifting in the upper
gears. I changed the transmission filter and fluid but the issue still
exists. I also changed the fuel filter. Any suggestions, I was going to take it to my local transmission shop for an evaluation so I wanted any thoughts on the problem. Are there any simple adjustments on this transmission?

The car did have the head gasket changed by Mercedes along with a
conversion to R134 air conditioning. Other than that it had regular
maintenance.

Any other thoughts on what to look out for this model and year would
be greatly appreciated.

Another issue that leads me away from the transmission and toward vacuum fuel issue is:

When I first start the car cold it idles fine. After it gets hot and I attempt
to start it up again the idle pulsates very high to very low rpms (1200 to 400)
before it settles within a minute to the normal 600 rpms. Hopefully someone
recognizes that symptom too!!!

If it turns out that the automatic transmission needs replacing, what
is the price range I should be looking to pay, I live in the suburbs of New
York City where the cost of living is pretty high.


Thanks


Bob
