I have a tork converter that locking the transmission and causing the truck to down shift and sometimes comes to a quick stop when braking. I am afraid if a family member drives the truck it could cause them to make a dangerous move in on goin traffic. Or not stopping and hitting a person or another vehicle. It hits hard and stops while pulling the vehicle in on coming traffic especially when not exspecting it all of a sudden.

When stop and starts going you can feel that gear gets stuck and it takes a sudden jump to the next gear and goes forward.

The transmission lost every gear but 1st, 2nd. I was driving it down the highway when it lost the gear putting myself, other motor vehicles, and pedestrians safety at risk. The transmissions are known to by others and gm to lose gears or blow and no recall has been issued to rectify the issues. the vehicle was scanned by a trusted local auto motive shop. there were no warning lamps messages or other symptoms prior to the failure. It was going down the road then slipped/sputtered, dropping in to second gear then the checking engine light came on.

I bought my 2019 Chevrolet Silverado 1500 RST used almost 2 years ago. I noticed shortly after buying it that the truck will stall in low gear then lunge forward unexpectedly, it didn't do it all the time just once in a while. Problem is it seems to be happening more frequently and varies in severity. I've asked the local GM dealerships about this issue several times while having it in for service or oil changes. But was told each time that its common with that transmission and nothing to be concerned about, the problem is that I am. I recently started doing research on this and noticed I'm not the only one having these same issues. I'm filing a report as it worries me that a vehicle I'm making payments on is acting this way. I'm also concerned that with the truck in drive and moving, without warning then lunges forward could cause myself or someone else serious injury or worse. This I believe is not the fault of the owner/driver, but GM itself. This problem is not an isolated issue, but one shared by many consumers, me included.

experienced several years of misfire problems, replaced spark plugs twice which seemed to fix the problem short term. while out of my home state(retraining for a new job in the Airforce) the misfire became significantly worse and made the truck undrivable. brought the truck to a local mechanic and they told me that I had bad misfires on the AFM/DOD cylinders and need to replace them all. chevy confirmed the diagnosis also stated there not going to offer coverage for this know issue. this know failure has costed me 15k in total costs when GM has know about this for years and could have fixed it before costing me so much money. I've also received no help from the chevy dealership or corporate regarding this know problem and I've been told its going to be an out of pocket repair and there's noting they will dop to help.

Recently had to have the transmission replaced on my truck. I was driving on an on-ramp onto a highway and my transmission would not change gears once reaching 50mph, where the speed limit was 70mph, causing me to almost be rear-ended. This was without warning, no lights came on and no other conditions were noticed prior to this event. I pulled off the highway and the transmission was making hard shuddering noises. I had a dealership look it over and they determined I needed a full transmission replacement. Upon researching online, this appears to be a common problem for this vehicle.

I am fully aware of of GM-??s Hydra-Matic 8L90 transmission or Hydra-Matic 8L45 transmission on the 2015-2019 models. My wife was driving with our kids on the highway yesterday and the trucks immediate shaking, increased high RPMs, slow acceleration and violent downshifting. Scared them very much on the highway while going at the normal speeds of 65mph trying weave through traffic and make it back home on top of that. With zero warning and this having happened on my first 2011 Chevy Silverado as well. I know full well there are more class action lawsuits against GM. Them being allowed to get away with this consistent problem and not owning up to their failed products is unacceptable.
