Hmmm, did you replace the valve body at the dealership under warranty or you replaced it somewhere else?
When did you start to notice the harsh shifting?

Hmmm.
Did the dealership perform a software update on the transmission by any chance?
That might had changed the behaviour as well.
When the transmission jerks, is there a strange sound that comes with it?
Another question is, what mode do you drive in? Eco, Comfort, Sport or Sport+?
Keep following up with your dealership.
If necessary, ask them to open a TIPS case with Germany to investigate.
Keep us updated.
Good luck!

I have a 2016 C450 with 25k miles, fully loaded. I had my dealership perform the transmission update on 01/22/2020 and that seemed to solve my problem with the jerks. Check out my post https://mbworld.org/forums/c450-c43-...re-update.html. The car shifts gears flawlessly and cant notice that there was ever a jerking problem before. I hope that my post helps I also updated the photos of my service tickets and dealership notes. Hope you get your issue resolved. I also have a 2015 C400 that has the same jerking sensation. I'm going to see if they can perform the same update to resolve the issue on my C400 cause the jerking is way more noticeable on that car than it was on my C450.

On the other hand, Khalidss' jerking issue happened after 40K KMs out of nowhere which is strange and the C43 has a different transmission than the C450 and C400 so not sure if the update helps but it just might.
Good luck getting your C400 fixed as well!

Thanks for the reply, I agree totally different transmissions. Never hurts to try though, but for it to start at 40k sounds weird. Have you had any issues with your C43? I was thinking about trading it for 2019 i really like the digital gauges and larger radio screen, as well as the rear diffuser. Not a big fan of the updated rear lights though.
The only things I like about the facelift will too be the changes in the interior.
Good question! The car does have occasional jerk and harsh shift on a 2017 C43 too but I've been busy, once I find time I will get it checked out along with the differential whining issue.
That being said, the dealership did say they installed an update to the Engine ECU and transmission TCU from last service visit back in January 1st which didn't fix the issue.

Same! Not a fan of those taillights! Although some will prefer it because it is "sportier". I prefer the pre facelift headlights too and maybe just me but I think the car sounds better than facelift.

HA that's funny I also like the pre-facelift ILS headlights. I don't think they look sportier at all. Does your car have the vibration at higher speeds? At first I thought it was only in the steering wheel, turns out you can feel it throughout the whole cabin. I was told by the dealer that I needed to have the tires re-balanced using the roadforce equipment. Does the whining noise happen when you let off the gas or does it haven while the gas pedal is pressed.
The whining issue was discussed here:
https://mbworld.org/forums/c450-c43-...-thoughts.html
The rear differential was the culprit.
For the vibration issue and yes thanks for asking which I do have, the culprit happens to be the driveshaft. The solution was to order a driveshaft that was balanced by AMG and not just Mercedes-Benz:

https://mbworld.org/forums/c450-c43-...ise-issue.html
https://mbworld.org/forums/c450-c43-...vibration.html
and apparently, this issue is present on the 2019 C43 too
Edit: The whining issue happens mostly when coasting, at light throttle or no throttle at all. Loudest when slightly braking at a downhill, if I apply more threshold than "slightly" braking the whining disappears even at a downhill other times it doesn't even whine despite the braking.
The most easiest way to produce this is to set cruise control to one of those speeds. Set the speed to 81 to 87 range.
To answer your question, yes unfortunately I do have the whining issue and the vibration issue on the 2017 C43

Not sure, everyone has a different taste afterall. Some like the facelift lights and others don't, we both don't. People are saying the facelift lights are brighter too because of 84 individual LEDs but that function is disabled in North America. There is slight power boost for the facelift and people say the suspension is more comfortable than pre-facelift others say it is finally more of an "AMG". I still believe in the V8 one-man one engine as the true "AMG" but whatever xD. It is a very nice car which I still love aside from these issues of course.

Curious question does anyone's PFL C43 so 2017-2018 still jerks noticeably after the latest software update sometime last year?
Does it jerk or jolt more in Eco mode than Comfort?

mine never jerks in comfort/eco. But S/S+ do rock back and forth in 1/2 and even 3 if you go over bumps. "Rocking" is harder in 1/2 S+.

I noticed my tranny is getting worse when it comes to jerking. Especially when down shifting from gear 4 to 3 and 3 to 2. It is relatively normal when it up shifts ... only jolts jerks and bang when downshifting.
Been having this issue for a while, and before noticing the whining of the rear differential.
Kept being convinced it is the characteristic of the vehicle but it seems like it is getting worse. Installed a tranny update last year December didn't help.

There are 2 types of jerking with this tranny: Forward kick (intended and by design) you get during upshifts when you floor it in S/S+. Other one is the "back and forth rock" you get in S/S+ in 1-2 gears when you drive over bumpy road. This one is obviously not intended but it is what it is. BMW DCT used on S55 does it too but that's a different type of tranny so not sure if they are comparable.

Yes, back in December, installed a software update didn't improve it. Shop foreman say cannot duplicate and they tried resetting adaptation which again didn't do anything. Checked torque converter lockup says normal. Oil is good and all.
They insisted that MB are technologically advanced if anything it will throw a check engine light.
They say it is normal to jerk as it is the characteristic of the vehicle and I tried to believe them until it seems to get worse.

Are they even thinking about 1. New diff 2. New propeller driveshaft ? Or every complaints are met with MB are high-tech and it working as intended.
I think you also need new valve body or have them get you a brand new transmission with new torque converter and new rear axle with new driveshaft and diff.
