Wow, thats depressing in such a otherwise good car. Need to get Corporate involved I guess. I'm hoping my 9 speed does not continue to get worse, it's no where's near as bad as my 2015 7 speed was.

Love my car but have the same issue on a 2015! Ive talked to my service advisor and corporate and everyone keeps telling me to wait for the software update. anyone know when it is planned to be released? I read previously January 2020?

Does Dealership Reply Contradict Most Everything on this Thread?
"Good morning. Sorry for the delay. Below is what my shop foreman responded back to me on the email, you had sent.
What this document does not show you is the history that we have encountered while performing this forced adaptation . I have performed many of these “forced adaptations” and most of the time the adaptations are unsuccessful in that the adaptations do not improve and you actually wind up with more undesirable numbers than you started with. The transmission engineer for the USA is Sergio Akusha. I have worked together with him on multiple PTSS cases for this exact issue . We have replaced transmissions, flashed software, removed and replaced transmission internal transmission components, replaced ME modules, all without improving this condition. The issue is not transmission related but the torque calculation between the engine control module and the information that it provides to the transmission to perform the best shift for ambient conditions. This statement is known by Cory Sarver , Sergio, Germany as well as others that have fought this issue along with much finger pointing back and forth between German transmission vs engine engineers that each say that it is the others problem. The latest information is … Germany has developed the software to correct this condition however it has not been certified for application, this is more than likely due to emissions certification. It is very easy to copy / paste / highlight / and comment on technical issues in an email with limited information however there is much more to this than meets the eye. I have reviewed the shift adaptation values for this vehicle that were retrieved on 1-6-2020 and the adaptation values for shift member B-2 are as follows: 11.5, 12.0 and 6.0. These three numbers represent low, moderate and high temperature ranges. These adaptation numbers are a typical for this shift member and actually not as high as usually seen. The low value of 11.5 is actually good comparatively speaking regarding other like models. If this client insists that we do a “forced“ adaptation the results are typically that the 11.5 value will trend to 15.0 – 17.0. This is a very undesirable outcome resulting in a more harsh shift than was present before and cannot be adapted back to the lower number!
I do not recommend this procedure. I have reviewed the LI document on this subject this morning and the cause is still listed as “uncertain” with no remedy listed. "

You all might think this strange I find this kind of response somewhat comforting in that there is complete and forthright discussion of the problem and communication with the transmission engineering staff. It makes sense that they can't just roll out a software upgrade due to emissions certification requirements.
Additionally it echos what my indy has told me when I inquired regarding having the transmission shift quality improved via road test adaptations.

I took mine in on Tuesday for a rough 5 > 4 downshift while cold. They are replacing the conductor plate.
They did say the technician spent most of the day on the line with someone doing tests and troubleshooting. I"m not sure what they were seeing because the rough shift only happened when the car was cold and was only bad on really cold mornings. It's been kinda warm lately. Maybe there is some history in there of shifts?

Curious about the mention of emissions compliance being needed for a software change to an existing car ... why would this be an issue? I could see if it were used on new production cars for the current model year, then the manufacturer's certification might conceivably be affected.
But in a repair situation, who would know the difference? When an ODB-II car is inspected annually for "emissions", all that's actually checked is that specific factory-equipped components (e.g. catalysts) are present and have no stored error codes. So a small change to transmission shift parameters couldn't possibly make a car fail in that context.

That's surprising to hear. How far back does this obligation go? If Mercedes made a software change for ten year old cars, would they have report a deviation to the certifying agency and seek a waiver?

The 2020 transmission update is being installed in my car right now, I will let you all know how it works (2015 S550).

can you reference the update number, serial number or any ID for that software so we can also reference it when speaking with our local MB dealership. Personally I am not going to risk downloading anything because what they did for me last year around sept. or october works as smooth as butter so far, but who knows what could happen anytime...

Picked up the car today. Skeleton crew right now for COVID so I was in and out. I looked at the document the tech provided and did not see any details surrounding the transmission update then asked if he could provide anything. He said he would have to grab the engineer for details as it was not in front of him. He left for 5 minutes and came back saying that the guy was busy but he'll try to email me something. Sorry this is not much help. The update seems to have worked for now, I drove around for 10 minutes or so then went home. I purposely tried to recreate the rough 5th to 4th downshift and its gone, for now. Time will tell I suppose, more to come.

I complained about the speed and it seems to be better now by maybe a second or two when flipping between certain screens.

Wow!, if it's better by 1-2 seconds, this means it used to take at least 3 seconds between windows!. In my case it doesn't take more than a second anyway to flip from one window to another, that's interesting, I wonder what could cause the system to slow down knowing it's a simple software and there should be nothing causing it to slow down.

2015 S550 4M. I printed this message out and took it to my dealer this week. I had reported this issue a year ago. They supposedly updated the software, but no help. Well, this time, the tech experienced the issue ( had to leave it overnight because the shift is worse when cold). They said there was new soft ware, they loaded it, then did dynamic shift calibration. It is a totally different car now. Why it took this long to identify this fix is beyond me, but I love the upgrade. Thanks for the post!

Too many german broads
I had mine updated late last year. It seems much better. Not sure how this "2020" update differs. I am under warranty, so if it worsens, ill just take it back.
