So.. I have 2019 LTZ 6.2L with literally all the options you can think of. I’ve had this truck for a year. Bought with 30,000 miles. I’m now at 70,****** miles. I’ve been hearing a rattle when I accelerate for at least 10,000 miles. My guess is transmission differential. The reason I say those two reasons is because when I’m driving, slowing to a yield, and then accelerate again I can hear and feel a significant jerk and gears trying to catch. It makes me cringe. Does anyone have any insight on this? Should I do a transmission flush? Thoughts? Help..
