C63 W205 rear vibrates during downshift from 5th to 4th
Hi,
Has anyone encountered following behavior or similar and know what might be the issue?
I have a C63 W205 Sedan (2020, 29k miles). When I manually shift down from 5th to 4th, I feel minor vibration and also sound different (some times more than others) than other gear downshift. It is always from 5th to 4th, All other seems just fine in all ranges of RPM. I brought it to MB and they have done transmission services and shifting adaptations. Also captured values and data during down shifting for MB eng and AMG to analyzed. MB and AMG came back said all numbers are within the range. I got my car back today and the shakes are still there and planning to bring it back to MB. I do feel that it is more mechanical (maybe MCT is missing a tooth??) than s/w issue and want to see if anyone had encountered similar issues and share.
Thank you and cheers
