Mineís a 2019 Estate. This car has one of the jerkiest stock auto transmissions Iíve ever driven, both on up shifts and downshifts. Perhaps it might be strengthened at factory for the higher power. In the tuning industry we often strengthen auto transmissions and they are generally jerky as a result.

It only drops to 1st gear when it comes to a complete stop and then restarts in 1st gear in Comfort mode. Is that normal? If not, Iíll do a video tomorrow.
Unless they've re-tuned for '19 MY (which I doubt), the lowest gear the transmission should drop to without driver intervention is 2nd gear when in Comfort and Slippery modes. Not sure about S because I've never used it, but S+ is the only setting that should automatically allow a downshift in to 1st.

I had same issue in Comfort. I went to the closest MB service for repair. They also asked me that if it's only in S+. It is ok so far. Mine is around 5600miles. I bought on April.

It's gotten better and you don't notice the jerking in Comfort now? I only have 700+ miles on mine as of yesterday. Did you adjust anything along the way?

Transmission shifting should be very smooth in Comfort. I am not familiar with the breaking process of a brand new car; can you ask your (or any) dealer to test drive a brand new C43 similar to yours to see if they are also jerky?

Thatís what Iím going to do tomorrow. I wouldnít be too surprised if they are not. But Iíll definitely ask why my 43 canít behave the same.

See the clip attached. Itís in Comfort mode and I also tested it in Slippery mode. Not sure if this is something new in 19 MY or just mine...

Mine doesnít. Maybe do a reset?

Did you select P when coming to a stop in that video?

Did you select Park in the video clip you shared?

If you wanted a similar ride, then you should have gone for the C300. Ive felt a difference coming from my 3 series where you can drive it mindless and it will never jerk; to my 2019 C43 coupe, but I just adjusted the way I interact with the throttle and no jerking since.
Like someone above said, you have to smooth into the throttle at low speeds and be decisive at fast speeds. It makes you actually pay attention and respect it as a performance car as opposed to a cruiser C300.

I didnít select Parking or anything at the stop. My car is definitely behaving a little differently. I just test drove another new C43 coupe today and it was smooth as hell. Really have no clue why itís like this now...

My transmission is very smooth in eco and comfort. Even in S I barely feel the shift. In S+ it gets a little nutty but that's expected. Definitely something wrong with your car. may be an easy fix like firmware flash or something.

You should try an e46 m3 with an SMG or even better was the e60 m5 with SMG LOL those were pretty horrible at times. After a few thousand miles on the c43 it's gotten better though.

E46 M3 in normal mode I donít recall it being jerky. The C43 is jerky in Comfort mode. E92 M3 DCT is pretty good too in comparison. At least in my experience.

DCT was so much nicer than the SMG's. Smoother at low speeds with much more reliability.
