Have a 2019 Sierra SLT X31, yeah, that's a mouthful. Anyway, when coming to a stop, I've noticed the transmission wants to "jerk" in 1st gear creating a bit of a thump, if you will. I've tried several ways of braking. Light, medium and heavy pedal. It still wants to jerk to a stop. At one time, back last year, every stop caused very hard down shifting. Of course the dealer found nothing.
Has anyone else had this or a similar issue? If so, what was the outcome?
