Just ask for the transmission update.
They'll do it for you.
Tell us how it worked, instead of how you didn't ask.
If that was directed at me, I've already stated repeatedly that my transmission software has been updated multiple times - including recently as part of the recall. There is no simple software fix for mine.

It wasn't directed at you.
But I'll say that I just got the NEW software installed last week, and the downshifting is much more gentle - UN-noticeable in fact.
My downshifting, at 40,000 miles, was just beginning to become harsh. I reported it as "harsh" and they said they'd install the "new" update. I didn't inquire further, and I just took the car out and drove like a fool, to "teach" my habits when I feel like having fun.
Usually a half hour of aggressive driving would cause the car to adopt that way of shifting, and it would take a week or more to convince it that I wanted to be luxurious.
After the NEW software download, it now reverts to luxury after all is said and done. I'm pleased.
You might call Service and ask if their software is "New." Worth a call, IMO.
Edit: this was not an "adaptation." It was a full download and update.
edit: BTW I did some 0-60 runs and I got 4.98, 4.99. 5.1 sec. at 5,300 ft elevation.
OP here. My GLE was at the dealership for a good few weeks due to other unrelated issues. I mentioned the harsh downshifting, but that was the least of the problems.
I got the car back a few days ago. The good news is that all other problems seem properly fixed and the car runs great. On the downshifting side, it's definitely much better – although not perfect. I can still feel the car hesitating a bit on the 5->4 (change of deceleration rate), but it's smooth and it doesn't really jerk – you wouldn't notice unless you are looking for it. On couple of occasions it was a bit more harsh, but it was in more aggressive braking situations so not really a problem. We will see how it evolve over the next few weeks.
Unfortunately the details for the downshifting fix in the paperwork are missing, so not really sure what they did. Probably reset adaptations.
While my car was at the dealer I had a 24 GLE 350 loaner. It was very smooth while braking, more than mine at the moment, but it was still not perfect – I felt occasional mild harshness when downshifting. I also had a 24 GLB 250 and that one was perfect, you couldn't feel the downshifting at all (it had regen braking – but it's a completely different transmission).
After a few hundred miles more on the car, it still has the same 5->4 harsh downshifting behavior. I presume nothing was done.
However I've been able to nail down when the issue happens more strongly: under heavier braking. The lower the initial speed and harder the braking, the more pronounced the issue is. If you break firmly (not very strongly either) when going at ~30mph on 5th gear you will get a pretty big "thumb" akin to the brakes clamping down pretty hard. I presume the transmission has less time to switch down the gears making the issue more obvious. It feels the transmission pretty much locks 4th gear instantaneously and you get all that harsh braking from the engine.
I'll mention this in the next service which should be in a few weeks. This time I'll get them to get to the bottom of this. It's annoying to be expecting this jolt every time you come to a stop.
I have a 2024 GLE 450 and I recently started to experience some harsh downshifting while breaking, for the last 2-4 weeks. Vehicle is 7 months and has 8,500 miles.
It happens around 40% of the time, but only if the car was in 5th gear or higher. Otherwise either it doesn't happen or it's so mild that I don't feel it. If you put the vehicle info screen with acceleration and braking you can see the braking going from 8% to 16% or so when this happens.It looks like the car is deliberately using 5->4 (and 5->3!) to apply a good bit of extra braking. But it's so much that is not smooth and gets annoying. In my case it lasts until coming to a stop, so I am not sure if it's the transmission or the whole braking behavior/system/programming. It seems more pronounced when there is a car in front of me, or there is a stop sign, so maybe? (I have driver assistance package). This may be totally placebo and instead it may be related to the current speed before braking. I am not sure if the assisted braking uses radar/stop information or not. I know the regen does, cranking the regen if there is a slowing vehicle in front.
I'll mention this to the dealership next time the car is there and I have a loaner. It would be great if they can reset the parameters to what it was before.
I've seen several posts over the years complaining about this behavior – I wonder if other folks with 2024 GLEs are experiencing this.
I have a 2022, and I've found the transmission shifting often clunky. I traded a 2017 GLE, it shifted smoothly. Needles to say I was disappointed when bought the 2022 and experienced it's clunky shifting,. Living with it for a little while till I trade it.

Did you attempt getting the dealership to fix it? I've read mixed results across the forums. Sometimes dealerships don't even try; other times it is solved with just SW, occasionally you will see folks getting new valve body or even full transmission.

Just took my 2020 gle450 in for oil change. They have a new software for the harsh downshifting. Been a week since I have my car back. No more harsh downshifting.

It's great to know the update has resolved your issues. I see this is for a 2020 450. Mine is a 2024 model manufactured in Nov 2023, I hope the update is recent and applies to my car too. I'll take it in 2-3 weeks for the A service and I'll bring this up – we will see.
Good to hear! Would you happen to have something in your service invoice like a technical bulletin number or software version that we can refer to when asking our service departments to perform the update?
Over the last couple of months, my GLE 53 has started to be a little clunky on deceleration to zero.
It seemed to me that it's rev-matching was getting a little confused.
So I took it in for my 40,000 mile checkup and they performed what was called a "Standstill adaptation." Apparently it didn't pass the initial adaptation, and it looks like it took twice for the Standstill Adaptation to take.
The transmission's confusion while coming to a stop is completely gone.
It really wasn't that much of a bother, but this forum alerted me to the issues and I was paying extra attention.

After 16,000 miles my 2024 GLE 450 developed an occasional hard downshift from 5-4. I dropped it off at the dealer and they did the standstill adaptation. So far, the fix has worked and 5-4 shifts are unnoticeable. No software updates were installed. I wonder if the software updates that some are getting are related to the recall for engine stalling and may not actually be for the hard downshifts.
It looks like this "Stand still adaptation" is working.
It's different from the one we do at home - some sequence of Ignition on, foot to floor wait etc.?
Apparently there is a verification that the Tech performs, since mine failed on his first try. See post #62.
Does anybody know what it does, and when they started using it?
