Don't know where to start. Its a new vehicle barely driven only have 4300 km on the odometer. But the problem is recent and intermittent. No check engine aswell making it harder to find out

When i am flooring it getting close to shift point 7k+ the engine will stop pulling like if you hit a wall for a brief moment and then go hard again. Happens here and there i never know when.

I was in track mode, shifter in D and traction control aswell advance trac completely turned off. By holding 10 second the switch

Need help, hopefully someone has gone thru this before me and can help

The only way around it is getting a reputable tuner with a 10R80 tune...

Go to HPTuners website and read all the threads regarding the 10R80 - here’s one regarding shift points and the limp mode:

The Dealership isn’t going to take your car out on the highway and up to 7k+ and “race it” to see if they can replicate the problem. Don’t expect them to do so....

Uh wait, my car isn't getting into limp mode, and my problem is not 6-7 gearshift it happens in all gear intermittent. But when it happens its 6800-7000 rpm i would say it happen quick just like the engine aint getting anymore fuel and then it pick up again and continue pulling. No check engine / No traction control light flashing either

But i understand the whole thing of, the dealer isn't going to take my car out to break speed limit and takes chance to crash it going WOT. But they don't have any worktools to verify fuel pressure or misfire stuff in real time datalogging ?

You were right, dealership did verification. Road test & they plugged it on oasis and ids.
Nothing wrong with the car, its just the way the transmission protects itself under rare circumstances.
