The manufacturer was notified of the failure. The failure mileage was approximately 80,000.
Transmission shakes, lurchers when driving, transmission stalls then engages abruptly at low speed and highway speed.
I experienced shuttering when accelerating, leaving Treasure Island garage. I got on the freeway and drove 11 miles. I experienced shuttering again after waiting at a red light. I experienced final shuttering after reaching another red light. Had it towed to the dealership and was told that the transmission was no longer operational. Truck was 5.5 years old with a little over 60k miles. I was on the way to pick up my daughter and thankfully, she was not in the truck when this occurred. Truck did routine maintenance at Chevy dealerships only. Fairway for the majority and Findlay the final year of its life.
Transmission Component: M5T: TRANSMISSION AUTO 8 SPD, 8L45 available for inspection. The vehicle shakes badly and shudders during acceleration and causes a brief inability to accelerate, often at higher speeds and with a great deal of rumbling and vibration. No other warning lamps, messages, or symptoms. The problem first appeared about 2 months ago. I recognized it as a persistent problem, and I was no longer comfortable driving the vehicle and feared that it would shut down while driving. I took my vehicle for diagnostic and maintenance at a local service center who also noticed that the transfer case "is making an unusual squeaking noise when driving". I was then notified that this is a known problem with this vehicle make and model for 2019 and referred here to file a complaint. Having less than 60K miles on this vehicle, I was referred to the dealership for possible next steps.
Vehicle will make a loud humming sound going 50 to 65mph and when letting off the gas pedal. It will stop when pressing on the gas pedal or when vehicle slows down below 50mph
I purchased my 2019 Chevy Colorado Z71 new in Feb 2019 from a dealership. About two years ago I began having shifting issues from 1st to 2nd gear, it would shudder and seem almost stuck, this would only occur infrequently. Right after I hit 100,000 miles (about a year ago) I have had nothing but issues with the 8 speed transmission, my vehicle is unable to shift from 1st to 2nd without having the shudder occur, it feels like the whole truck is shaking and loses power at acceleration. I took it in for their recommended "service bulletin" which was something that I had to locate myself because GM has not once communicated about there being any kind of shudder issue and they performed a simple flush of the transmission, not the service bulletin recommendation of three flushes and a different fluid. My truck is now in the shop because I am unable to drive it due to this ongoing issue that GM fails to recognize and so far have spent $1,000 attempting to rectify this issue and being told that in order for them to actually perform the service bulletin, it will be another $225 to diagnose the problem, around $500-$700 to perform the service bulletin, and then if that "does not fix the problem", I will have to spend another $900 on a torque converter because that "could" be the issue, the dealership "doesn't know". Then the third fix would be to replace the transmission ($5500-$8500) This has been a known issue since manufacturing and GM is failing to provide adequate assistance to fix a known problem with their 8 speed transmissions. I no longer feel safe to operate my chevy colorado in fear that it could cause serious injury to myself and others due to GM not being able to provide a safe fix to their ongoing issue.
Transmission Issues — Shudder And Vibration; Stuttering; Vibration And Slams Into Gear At Low Speeds When Going Into Gear. Problem has been confirmed by a independent service center. No warning lights. No codes detected by service center. Bought in May of 2019. 47,000 miles. Noticed about two months ago,
My vehicle has only 70,000 miles on it. My transmission began to shimmy and is getting worse and worse and several technicians have told me the transmission will have to be replaced. The parts are not available anywhere in the country to rebuild the parts of the transmission that are defective. Secondly I was told I could replace the transmission but there are no transmissions available in the entire country to repair my vehicle with. After investigation on the internet this is a massive problem with this model vehicle and Chevy has been well aware of it for years. A few months ago I had the same problem with them air conditioner compressor. There were no air conditioner compressors available anywhere in the country for my four and a half year old vehicle.

truck has intermittent vibration at highway speeds and they are getting worse. The dealer just called and said the torque converter was shot. That seems to be a great deal of the power train complaints

Transmission slips when starting on steep grades when first shifting from Park to first gear. Transmission hesitates/shudders between first and second gears.
The stabitrac system malfunctioned and went into low power mode while on the highway almost in an accident because of speed loss. The button to turn it off did nothing. Still unsure what caused this to malfunction but needs to be a way to override to maintain speed without power loss
The truck has a hard downshift and when stopping and starting again at a stop sign it will lunge forward sometimes.Also,when holding speed at 50-60 mph you can feel a slight shutter like the truck is not running correctly.The dealer flushed the transmission when I purchased the truck but the issue continued so I made an appointment with the service department on march 3,2023.They took the truck on a road test and did notice the hard downshift and noted that this is a normal characteristic of this transmission(this is not normal and is unsafe)and will not offer to repair it.It is now the end of July 2023 and the issue continues and no one seems to want to do anything about it.I am going to take it back again but I am probably going to get the same answer
