Ive noticed recently in the garage as im leaving (car isnt fully warmed yet) that the car will shift abruptly from 2nd to first gear. Its almost like a slight jerking - its just not smooth. I saw a post about this in manual mode but has anyone else dealt with this in auto-sport mode?

My 2012 does this when I move from C to S+ when stopped.

ive noticed the same but after my 2012 warms up it seems to go away = / maybe it just needs to warm up?

what do you expect when the engine, tranny, and diff fluid are cold....smooth as butter?

i find that driving at low speeds in anything other than c mode is jerky. this is why i wish the c63 was offered in a 6mt (really not a fan of any "performance" auto)

I always drive on an open road in s...but as soon as i hit traffic or go into a slow area...i change it immediately to c because otherwise it jerks

Yep, S/S+ when the car is cold is jerky for me too. After warming up it goes away.

I just got my car back from the dealer today I explained to them the same issue your having I have to bring the car back in a week for them to reset the transmission I have to drop the car there over night so its right cold in the morning they will

Reprogram the "cold shifting adaptation"

I have driven other performance cars and you get a hard shift on like a racing clutch when you shift up but not down...

My car is a 2008 fyi

Got my 3rd (Service A) oil change last week and it's stopped doing this since

My tranny is very jerky in the cold...smooth as silk when warm, though.
