I've been browsing these forums for a long time - however decided to get my *** on this after recently taking delivery of a C43... I must say, I LOVE the car. So practical and enjoyable to drive.
I have broken in the car in record time and have been in Sport+ in almost all my drives since. One of the issues I'm finding while in Automatic is from a stop going through lower RPM (especially on turns); I get violent stuttering forcing me to jump on the paddles to correct it or I have to be far more aggressive on the gas to get past those gears. I've driven lots of AMG's across the line and haven't experienced something like this before. Is this a common issue?
I have it too. It is like a VIOLENT shaking in first gear but only twice in the past 24 hours. You have to upshift into 2 to correct. Also slowing down in sport plus, to a stop, car can be jerky. I have a feeling they don’t ship with latest firmware.

I have an '18 43 coupe delivered in Jan. I experienced this a couple of times early on but it has apparently completely resolved itself.
No problem now at all. If it doesn't recurr, I will not let them update any software. Its running too good now to chance changing anything. If it comes back, I will let them update.
Have seen several posts on here where several others have said their "bunny-hop" issue resolved itself as well.
Gremlins?
there is a transmission software update that is supposed to correct that problem
when I took my car in for annual service last week my dealer did a fuel system update and insisted there was no transmission update despite my complaints of the bunny hopping.

do you have a sedan or coupe? For some reason I’ve heard the update doesn’t include coupes or cabriolet??
It is obviously not normal. It is violent jerking back and forth and a failure to upshift.
S+ wasn't designed for puttering around town, I remember Maserati/Ferrari transmissions had similar issues. They were tuned for track driving, @ normal city driving, they jerked, clunked and banged into gear.
Well you can drive around town 98% of the time. When Sport + behaves correctly 98 percent of the time, and goes bonkers 2% of the time, something is wrong. I wasn't even puttering, I was accelerating off the line and it stayed in 1st and just jerked back and forth VIOLENTLY.
I know what you're talking about, the violent jerking back and forth in 1st gear. A lot of people on here have experienced the same thing.
I told my service advisor, and they said they had a previous C43 that exhibited the same problem, and that there should be a software update for it. Hopefully when I get it back the issue is resolved.
if the techs don’t take it out and tune it, the software is useless.
tune what?? It’s a software update for the TCU, not the ECU.. many people have gotten it already and they say it solves the problem.. I myself am going this Tuesday to get it along with the fuel system software update TSB
To others that think this is a problem with the car, it’s not.
its a sensitive throttle and when you hit a bump, your foot jerks and causes the bunny hop. Some people like this, some don’t. The update apparently adjusts this so it’s not as sensitive.
It does have something to do with bumps and road imperfections because I can reproduce it consistently in parking lot near my office which has potholes. Its right after a stop sign, car is in first and i get to the rough patch around time I would normally let car upshift, but instead i ease off gas in first and car goes nuts. This is in Sport Plus of course.
Not sure if I should ask for firmware or not.
Got the update today and all gearbox issues seem to be resolved.
I do miss the "UP" from the dash and heads up display though
So other than the missing upshift prompt does the car drive better overall after the update? Can you describe the improvements? Any downsides to doing it other than the missing upshift prompt?

I haven't noticed any downsides other than that.
Before, the car would occasionally hold 1st gear right up to redline and then shift incredibly slowly, lurching into second.
I got the transmission update and I got the fuel system update too..seems to switch gears faster and more precise in automatic mode and no lag in between shifts like before.. also the “bunny hop” in s+ 1st gear is pretty much gone.. my 0-60 seem to have gotten better according to my dragy also.. I would say over all it is definitely an improvement.. here’s my work order in case anyone is looking to tell there dealer about it.. I just told them my car was not smooth in s+ and a friend who has the same car got a software update to fix the problem for the transmission...they have to hook up the car to there diagnostics equipment to see if your car qualifys for the software because some may already have it from the factory.. only way for them to tell is to hook your car up.. the VIN won’t tell them, they have to hook the car up to STAR diagnostics and see what version software is on your TSU ..... the fuel software is a TSB so that they can find easily!
