Race mode hard shift
Im at track day in race mode with Sport handling and trans in dynamic. Everything I come up to 100 MPH the car jolts like I hit a governor, No light no cel not traction and oil water are all good temp. It drive like a champ u till it hit 100 jolts then keeps going?
This is the first time in Race mode, usually drove in S+, Anyone else happen to experience this?

Wow, that was the most retarded post. That's what I get for typing so fast in the pit. Anyways, I think the car might be just redlining, like it doesn't shift itself fast enough and redlines. It's never happened any other time in any other mode when accelerating. Any thoughts???

If it is in manual and you don't pull the paddle early enough it could be the governor.
never happened to me yet.

Bringin this back to life, at the track again doing the same thing. In auto so it’s shifting in its own. Not hitting the rev limit either but feel like it. Anyone one experience anything similar?
Kind of hard to have mercedes diagnose unless the find a spot to get that fast. And I doubt MB would approve letting them.

Mine does the same in race mode when auto-shifting from 3 to 4... which also happens to be about 100mph.
The weird thing is that it doesn't do it every time and if I manually shift before it hits the rev-limited auto-shift, it shifts just fine. Seems to happen about 2/3's of the time to me. I told the service rep about this at my last service and he could find nothing in the logs to support my complaint.

I happen to catch it on video. I’ll try to load them up on here. I’m taking it into MB next week with the video.
Its not not something that should be happening. And there is a horrible noise assosiated with it. Almost seems like misfire and it pulls timing, so hopefully it is just octane related.

Maybe you have the same issue this person had -- transmission fluid foaming which caused slow shifts which caused ECU to rev-limit when shifting 3-to-4 (visit the YouTube page and read the notes with the video):
Earlier videos show the "missing when shifting 3-to-4" issue.
