Oh that makes sense. I thought they returned it to you already but despite that, your service advisor should keep you posted on what is done, like what update applied.

Yes they have told us about the "updates" to the transmission and the transfercase... but no specific name... to what update. Today... there hass been no response from the dealer. All they said yesterday is that they where in constant talks to MB Germany about the case.

Sorry to hear that, what do you mean it came back and worse than before, did you do the recall update, stand still adaptation or forced adaptation? How many miles since that was done?

It took my dealer 3 tries to reduce the jerk to an acceptible level. They are a great dealer, so I know they did their best. I get a jerk on rolling stops until the xmission warms up. If I ever need another car (I have mine warrantied until 2029 and I only drive about 3500 miles per year) I'll be looking at a used Bentley or Rolls which have mostly real buttons and toggles. I also can't stand the touch/swipe pads on the MB steering wheel and console. Massive service costs, but way better to drive.

Hi all,
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.

They cannot resolve the jerky transmission, and I just keep taking the car in and they just do a reset and send me on my way a week later. I can't just keep taking the car back and forth to the dealer, this just doesn't make sense. I had a 2022 C300 that they did a lemon law buyback on, because it had all the bells and whistle, and everything kept malfunctioning, and I had videos etc.. but this, itis just hard to video. But I am now going to buy a camera, so I can document it when I take them to court. I have a lemon law attorney for this one too.. it seems like this new tech they have in these cars from 22-24 so far have some crazy issues. It's all over the net with others having the same issues. I don't understand why they don't have a fix.

I haven't commented on the ongoing transmission saga in a while, but I'm not surprised it remains a source of frustration for some owners. I myself relocated back to PA, which gave me an opportunity to try another dealership when our GLE was in for its most recent service a few months ago. My car is out of warranty, so even though our issues were well documented, I still had to pay out of pocket to have the transmission looked at. The dealership had my car for the better part of three days, and performed numerous standstill adaptations during its stay. As a courtesy, I was "only" charged $750 for the work. The result: marginally improved downshifting, but it still acts up at times and seems to be worsening again. My wife is convinced the upshifts have now become more abrupt since the adaptation, and we both agree the transmission's behavior is miles from how it performed when we drove the car off the lot. Thankfully I have my car, and she works 100% from home now. so neither of us drives it much. She frequently comments how she misses her GLC and its nearly-flawless 9-speed. I thought she might be interested in a GLC53 AMG when it gets the inline six, but when I asked about it she responded without hesitation "NO EFFING WAY!!!". I'm not upset by that.

Correction to my previous post: the estimate for the transmission service was $750, but the service manager waived the fee. I was not charged for the standstill adaptations.

This may not be valid for a 2021 model. It may be worth showing this to your service manager.

Repeated standstill adaptations, although the paperwork doesn't show how many times they did it. There were no software updates.

The second eliminated the co-driver, and was able to be administered by one tech, but still required more than one repetition to verify success.
I'm probably wrong about the year and the details, so someone please help here.
The gist of my post is that the former and now obsolete procedure had limited success, while the new version worked well.
I had both performed - the first made no perceivable improvement. The second Stand Still (two words) Adaptation was successful. It was right after the new procedure was available and it was the first that the shop had performed.
However, after an automatic update last year, my engine "stumbles" a bit as I approach a stop, like it goes into Start/Stop at 5mph but recovers almost immediately. That symptom is not predictable, so I haven't mentioned it to the shop, since I'm not sure they could replicate the symptom. This doesn't seem like a tranny issue. It's not noticeable to my passengers or harsh at all.

There are two kinds of stand still adaptations. The earlier (pre '24?) required two technicians, one to drive and the other to monitor, and required several repetitions to verify that it "took."

As well as something called forced adaptation.
