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?

This topic has been listed some years ago as well. Apparently MB in my area call it one of "the characteristics transmission for GLE". All those new software update also did not help at all.
Many of us some prefer to press the brakes slowly or softly to a halt while the gear downshift nicely when coming to a traffic light stop or any junction. But with this GLE, it does NOT gives you that smooth downshifts which is very annoying.
What can we do about it? Well, sometimes i will purposely press the brakes more firmly to eliminate that kind of jerk.
I complaint about this when i had the car the first few days. Was not use to it. Its a great car to drive overall.
Everything starts from 4th gear to 3rd gear to 2nd gear. You can see the engine will rev up whereby the jerk or jolt will happen.
Just get use to it. after some months you will be able to control the braking.
Not disagreeing with others, but frankly speaking ALL THE WAYS OR WHATEVER BEEN PROPOSE TO ERADICATE THIS ISSUE DO NOT WORK AT ALL. everyone drives differently, brake differently.

I've always been one that brakes easily to a stop. The standstill adaptation performed on my 2024 GLE 450 has so far eliminated the rough downshift from 5 to 4.
The software updates are a separate fix for an engine stalling problem. The updates have nothing to do with the rough downshift. I would print out the posted info from other users regarding the standstill adaptation and demand that the dealer explain why they don't need to follow the procedure.

I agree, this should be addressed properly by Mercedes as everyone would expect for their car to downshift smoothly when coming to a stop. My dealership told me it is normal for Mercedes transmission to have this , and cannot be seen in CVT transmission. This reason is definitely b**s***
they wrote the following officially on the paper :
CUSTOMER STATES THE VEHICLE IS ROUGH WHEN DOWNSHIFTING-- ESPECIALLY FROM 4 TO 3 . TOOK VEHICLE OUT FOR TEST DRIVE FOR CUSTOMER CONCERN. ATTEMPTED MULTIPLE TIMES TO SEE IF TRANSMISSION WOULD FEEL ROUGH. WILL NEED MORE INFORMATION AFTER TEST DRIVE, FOUND NOTHING WRONG WITH I T , UNABLE TO RAN A QUICK TEST FOR CODES, NOTHING STORED, CURRENT OR PENDING. INSPECTED TO SEE IF TRANSMISSION HAD A AVAILABLE UPDATE. NOTHING WAS AVAILABLE. PROCEEDED TO DO A 2ND TEST DRIVE FOR A "ROUGH" SHIFT BUT WAS UNSUCCESSFULLY ABLE TO FIND SOMETHING.
I truly believe that a 80K car should not feel weird when driving and dealership should not normalize this behavior because they cannot solve or fix it. The development team within Mercedes need to know about the existing issues. This topic needs to run hot to get highlighted.
I have now got used to it as the car drives well overall except this nuisance which occurs almost in sport, comfort or eco.
mercedes support is pathetic and I have learnt this so far. The technical support is only good for questions like how to start and stop car etc . If you show them some complex issue , they will just ignore you and have a bottomline in signature saying Customer's satisfaction is their top priority lol . If you tell them that something is working on A but NOT B , they will tell you that yes it is expected without telling You why it is working on A and not B . Just useless.

The vehicle (GLE) overall is good but the transmission definitely left a lot to be desired, it is disappointing that even S-Class have this issue, thankfully not all GLE has this issue. This might sound weird but I heard people saying the transmission is smoother in sport mode than comfort, the shifts are less jerky... for some reason. Could try that.
Although GLE 350 has these transmission issues as well, I do hear more about them reported on the GLE 450, maybe because the GLE 450 sells more or maybe because the complexity of the 48V mild hybrid makes the transmission confused (in a way, anyways). The auto start/stop also doesn't help cutting the engine before coming to a stop or cutting the engine when coasting.

Thanks to Mikapen and BlueYonder for posting pictures of their "standstill adaptation" service. I mentioned this during my A service appointment and provided their screenshots, and the dealer performed the same standstill adaption. Just offering another data point in case it helps others. Haven't driven the car enough since picking it up to see if there is an improvement (though to be fair, when I first got the car 5 years ago the downshifts were very noticeable, but have gotten a bit better over time).

Let's hope. My shifting has been better since the Standstill Adaptation. So far.
Mine only started getting harsh at about 28,000 miles.
It seemed to me that the Rev Matching the tranny does on downshifting was getting confused. Maybe.

That is good news, I am still curious the difference between this and "Forced adaptation" though.
When it says valve flush in the pic above, do you know if they did that part or did they just skip it and ran the standstill adaptation programming again?
