I hve a 98 C230 with 92k miles...the car runs well and looks great, so I am not thinking of trading. However, in recent days, I have noticed the definite feel and sound of a "thunk" when I am slow rolling, as in heavy traffic, from 1st to 2nd and similarly when downshifting from 2nd to first.
I know that the tranny case is sealed, but I am still thinking that a change of fluid and filter would not be a bad idea. If anyone has some experience with what I hope is a minor problem, thanks for your help and advice.
