Shifting hard from 1st to 2nd... anything to worry about?

I know, all the slk 55 amgs have a slight jolt from 2nd to 1st when slowly coming to a halt but the jolt from 1st to 2nd is a little stronger.

I've searched and found several threads on the matter but nothing conclusive. Most of them say to disconnect the battery for an hour or drive it really hard in Sport mode.

Do i need to worry about 1 => 2 jolt?

have many encountered this and had it for a while?

It's always kinda bugged me too. I can upshift/downshift a manual trans smoother. It does seem to be a little better in "C" mode. I've had our amg in for servicing a couple of times and the dealer says it's "normal".

the jolt down from 2nd to first almost seems like it's occurring because the the car is shifting too early or something.

you can reproduce the jolt if you shift 2nd to 1st at around 10mph. if the shift occurs at 6-8 mph, there's no jolt.

never had a problem with a jolt 1st to 2nd.
