E4.50 transmission
After driving my new E450 for a few weeks now,I find that the transmission does not always shift smoothly.I noticed a few times that if I slow down where the transmission shifts down from 3rd to 2nd gear and then accelerate, the transmission Almost slams into second gear.As if, for a second, it was just in between gears, almost in neutral, and when I try to accelerate, it will slam into second gear.It will only do it once in a while, but I never had that in my wive’s GLC 300 which does not have a mild hybrid engine.
does anybody had a similar experience with the transmission?

Mine does the same thing. Only 350 miles on the car so far. I can live with it. My 2018 S class does the same thing. I’m not all that worried about it. If it goes back to the dealer they probably will have the car a long time and I’ll come out of there with the same issue. At least on my car it’s not all that bad. Gets the rough downshifts maybe a couple times a day if that.

Start/stop is one thing, but do you drive in Eco mode? If so, the car will try to coast - turn off the combustion engine and use the 48V system to maintain speed for a short while. This might be what you're seeing when you suddenly accelerate and the car turns the combustion engine back on.

I would try driving in sport and sport+ mode for a few days. Let the engine rev hang and accelerate. See if its a transmission issue or a computer shift point issue. You may be more a spirited driver and the Comfort or Eco mode your currently in might be a tad relaxed for your driving style. Ive gotten use to comfort mode and know the shift point pretty well. Once you get use to your vehicle and your vehicle gets use to you, you will figure out the power delivery.

I’ll probably be driving mine mostly in sport mode as I notice the sport mode is fairly mild compared to previous models and does not hold gears too long and I’ve seen it even shift into 9th before 65 mph. I have not seen the car jump around or rough shifts yet in sport mode. Then again I’ve only driven the car 325 miles.

9 speed transmission jerk
Many of the the Mercedes 9 speed transmissions have this problems. There is a thread about it in the W213 area. I've owned 2 different W213's and they both had the problem. The dealer has tried to fix it 3 times with no luck. Has nothing to do with sport mode or driving style. There might be other problems which do. I've lived with this for 2 years and tried many things - none of them worked for more that 1-2 days.

I'm not having any of these issues on my 2025 E450. Shifts are buttery smooth. The 2024 E350 I had for a few months was also smooth.
I can confuse the computer if I hit the gas hard and then back off. It will stay in a lower gear and to keep the RPMs up in anticipation I keep on the gas. It takes a few seconds to realize I am not getting on it any longer and shift up.

I have the same thing in my GLE if I hit the gas hard and then back off. Also, if I start braking hard and then change my mind and want to accelerate hard, it will take a moment to change from "I guess I'm going down through the gears" to "I now have to quickly go up through the gears" and there can be some hesitation and jerking because of being in too low a gear. I can imagine that with very spirited driving this can become an issue.

MB is not the owner of this site and are not obligated to monitor this site for customer feedback. They have official channels for that. This site, like many other similar sites, are for enthusiasts who own a MB and people who want to learn from other owners about their car. They (MB) may read some sites and quite possibly this one, but not in the capacity you are implying. An official MB representative will not likely engage with you or anyone else on this site. At least not in an official sense.

Just wondering how many of us go on the official site to tell them about the transmission issue. Seems they would learn a lot - and be able to improve things if they read this. Unless one of you have written about the transmission on that MB site.

Your best bet is to message MBUSA directly. That is the only way I know of to send feedback or ask questions. They are however, somewhat useless and more often than not will refer you to your dealer.
