SOLUTION (in my experience)

I had the exact same problem on all 3 of my w123 300d's to some extent.
.

And EVERY SINGLE ONE WAS FIXED with a simple ATF drain and refill, replace the filter and gasket as well of course.

AND IF YOU DONT WANT THIS TO HAPPEN AGAIN, use a German ATF, a correct fluid can be bought here at pelican parts. It will cost a little more but I say its necessary.

No one changes their ATF enough, if at all. It needs to happen Everytime you buy a new Benz or every 50k or so.


If it was a vacuum, vcv, or modulator issue he wouldn't only be experiencing these problems at FOT, it would be noticeable much sooner if he had a slow vacuum leak in his system somewhere. But don't get me wrong, u do need to go thru all the steps to make sure Ur getting best performance and making sure no future problems will happens
