auto transmission jolt in sports mode
I have a C63s 2016 amg and was wondering has anyone had a problem when they have their car in sports mode and when driving to say slow down to a set of lights from 2nd to first they get a shocking jolt when changing down gears? Has anyone had this and whats the procedure to reset the transmission module? I tried the accelerator procedure but did nothing. I also had the gear oil changed recently to see if it would help.

I experience the exact same thing in sport+, never drove in sport before lol. I think this is just the nature of these transmissions as others have experienced the same thing. I usually just drive in manual and down shift at higher rpm's so I can hear the pops and avoid this jerk

Is there a way to tell if TCU has been updated? I got the engine update for the pops/crackles but I still get jerky shifts at low speeds in sport+

If you got that engine update then the TCU should have been done at the same time. Perhaps that is not the issue here.

My transmission is also jerky in Sport+ (which I think is expected because the transmission is wanting to be aggressive for spirited driving), but quite smooth for the most part in Sport. I might call a local shop that is AMG certified to verify the TCU upgrade, as Merc likes to avoid fixing stuff lol I've noticed. They tend to act dumb so they can focus on making $$$ on customers that are out of warranty.

Mine does this as well. Roll to a stop and it jolts into first. Dealership found no problems but my dealership is not really good so who knows. They say it's up to date.
