Update on rough transmission downshifting
Was reproducible.
They said they are aware of it, but no fix exists.
AMG version has same issue, but worse, and there is a fix for that per dealer.
He will be talking to MB rep later this week.
Very frustrating.
I also indicated a lack of full screen CarPlay and interior rattles with CarPlay my suggested JD Power to MB communication item lol. They need it implement full-screen now. I don’t care about losing the climate control indicators. They can make it so the climate control only appears while adjusting while full screen CarPlay is active.

Sorry about your car. Most of us don't have your issues.
If you want wireless, just enable your Bluetooth connection and it'll start when you turn on the ignition.
All Waze has ever done for me is to reroute into a traffic jam. They are trying to fix the reporting problems, but so far no luck. It's inherent in their model.
The MB Near system, with better Car-to-X implementation, is the future of Nav.

CUSTOMER STATES TRANSMISSION SHIFTS HARD ON DOWNSHIFTS
Tech: Ran quick test found no codes. Found PTSS cases for same issue, some performed software updates to fix issue. Performed software updates on trans and transfer case. Test drove car is now shifting properly.
Well, the tech is full of it ... the harsh downshift remains. No improvement whatsoever. The frustration is building ...
I am consistently seeing posts stating replacement of the valve body results in a permanent fix.
My issues: rough downshift from 3-2, clanking and lurching, screeching at 2-1 downshifts.
The transmission with produce a "thud" and vehicle lurches when shifting from P to D and vice versa.
It is progressively worse when driving in Sport vs driving in Comfort.

My service report only states "PERFORMED ADTAPTIONS OF TRANS MODULE" @mikapen loves the spelling

I will take below to the dealership and let's see how it goes, will update here once there's news...
Interestingly from what I can discern from the comments below it appears that this simply forces the learning pattern the transmission is supposed to make anyway.
Guessing my transmission learned the wrong things since day one...

A) There’s absolutely no reason for any owner to have to endure an additional “transmission adaptation” other than to cover up incompetence and ignorance.
B] We shouldn’t have to do a dumb “transmission adaptation” if the morons at MB engineered it correctly to begin with.
C) The lead transmission engineer is probably some executive running the company.
