CLS63 Transmission problems

I just picked up my CLS63 today and put a 100 miles on her driving around. I noticed when the car shifts that the transmission makes a clunk sound and is very rough. Can anyone please help????????

If this happened at low speed MB can adjust this for you. There is a MB service bulletin out. I drove a Bluetec E320 and had the same experience when the car shifted from second to first. There is a fairly sharp "jerk" but once the car gets going it is very smooth.

does it happen on the 2-3 down shift or does it only do it on acceleration?if so no big deal it is either a valve body software flash, or b1-b3 clip .bring it to the dealer and they will get it done ,i have done alot of them no 63s yet but they are all the same ......
