Transmission shakes rattles and jerks and has since I got it brand new. Intermittent issue normally but sometimes it's extremely aggressive and legitimately causes a whiplash motion.
The transmissions will shudder and delay shifting gears. I have pulled into a parking lot and put it in park, then I realize I'm a foot back I put it back in drive, the car doesn't do anything for a second then it lurches forward in an unsafe / uncontrolled manner. Often backing out of the driveway, then putting it into park and the same delay then launch happens. Gm has serviced it 3 times and the problems still exist but the shifting is now much more rough than before. The problem & risk continue today.
