Fyi my dealer has been very unwilling to do this on my 2020 S560. The shifts absolutely drive me crazy. They are saying there may be a software update in June, though I’m skeptical.
Others have posted about success doing this themselves with Xentry. I’ve tried to do it but can’t figure out how. I’ve asked others to share step by step instructions and no one has been willing thus far - though I realize it is a lot to ask. BenzNinja has offered to try figuring it out but I haven’t had a chance to connect with him yet.
good luck and keep us updated.

Still have a little less than 4 years left in extended MB CPO warranty. The head tech said he feels the rough shifts but that they are within spec.

The dealer replaced the electrohyrdraulic controller unit. Fingers crossed that this actually fixed the problem. I'm still waiting on the car because they are also replacing the exterior window trim.

Do you mind posting the work order, don't worry about it if you don't want to.

let us know how it goes. I hope it works. While am not trying to scare you, personally I feel that this might not fix the inherent issue that most of owners are facing. To me, only the active force adaptation can fix (tech driving the car, computer connected, another tech in the passenger seat force-adapting all the shift points). This is already documented within the Mbenz service bulletins. Changing electrohyrdraulic controller unit may fix it for the first few days or 1-3 weeks for the first couple 100 miles, just like what a cheap coding/software reset would do. However, if the controller unit was truly damaged, that might fix it so let's see. Also, there is a chance that they have done force adaptation as a part of installing the new controller unit. In all case, keep the community here updated please, and good luck.

Cause
Faulty electrohyrdraulic controller unit
Correction
Remove oil pan from automatic transmission, remove & replace electrohyrdraulic controller unit, install in reverse order. performed initial start up of electrohyrdraulic controller unit.fw Customer will need to drive 300 miles for valve body to adapt to driving style .

I forgot to scan the printout they gave me, but here is the description from the online portal of what they did. I will check the work order when I get home to see if there is any additional information on part # or description. They had the car for almost 2 weeks, which I imagine was mostly waiting on the part. So far, I do notice an improvement. I can still feel the 3-2 downshift being overly harsh, but not as frequently and not as severe as it was before. They are claiming that the transmission needs 300 miles to adapt to driving style, so fingers crossed, but I am skeptical and share the concern of S_W222.

Yes, that is it. I was curious and found it weird it wasn't documented they did that but they couldn't have reused the fluid anyways.
