Yes, and there are existing threads about it.
I think it's a combination of possibly 6/4 cylinder switching, but more so shifting 2-4 for fuel economy. I find it only happens under light throttle and/or low RPM shift.
My manual tranny Z06, in stock form, would force a 1-4 shift under certain conditions (low throttle, low RPM shift...).
Makes sense to me.

Yes. Taken my 2017 Denali in numerous times now, many reflashes, TCM, torque converter replaced and still worse than ever. Got GM corporate involved to push for a new trans. We shall see where that goes.
