I purchased a 2019 Silverado (new body) 5.3L 8-speed with 50k miles and noticed the problematic shifting patterns soon thereafter. I immediately brought it to the dealer's attention but they treated the complaint as if I was nuts. I purposely did not drive the truck that much in order to keep mileage under the 60k power train warranty threshold. During that time I stayed in contact with the service and sales departments and reminded them of the ongoing transmission issues. Now at 64k miles I feel I've been put out to pasture! Update: No resolution from service department after several visits (they wont take the truck and drive it as their own for a few days) and after they performed "reprogramming". So here's what I have @64k miles: *Hard hitting shifting between 1-2-3 both warm and cold *Delayed shifting especially noticeble when making turns from a stop *Lurching and erratic downshifts *Intermittant, very hard (banging) from FWD-REV-FWD (real teeth clanker!) *Very noticelable and discomforting high frequency vibration from center tunnel area (like an out-of-balance driveshaft) My concern over the long-term is drivetrain damage to other components and failure on the road. If I was the original owner I'd "lemon law" this truck in a heartbeat! I'd really like to know if the 10-speed can be retrofit into my truck since it's now offered on the 2022. Thanks!
