My truck has been shuddering and when put into gear it sounds like the bottom is falling out of it. Now when I am driving my truck is shuddering very hard and skipping gears. I have been having this issue since I bought the truck with only 47k miles and I have only put 40k miles on this truck in the past 3 years that I have owned it. I keep the maintenance up on my truck and have since I’ve owned it and I have already put a complaint into GM, when I bought the truck it has had electrical issues and the dealership is not helping. My warranty is out on this truck and GM said there is nothing they can do to help with my transmission or electrical problems. This truck has not even hit 100k and I’m so upset that I am having these many problems and no one is wanting to help, they just want my money. I can’t afford an attorney or I would sue this dealership for selling me a Lemon and for GM knowing about there faulty transmission in my year truck and not standing behind it!

Shudder or vibration when accelerating by model year
What owners say
Torque converter shudder. Had dealer do the recommended flush which cost $800 and still has same issue.
This vehicle suffers from a torque converter/transmission shudder after the transfer mission fluid heats up. My initial complaint to the selling dealer and they did not follow the GM posted procedure and initially charged me for the service. I’ve changed dealerships and I’ve been told it the temporary fix is to do a flush and there is no permanent fix by GM. I have had situations where and unexperienced driver would have definitely got into a car accident and I don’t let anybody drive my car because I believe it is unsafe. So far the dealer has been accommodating while under warranty but advised I reach out to GM who then advised to review my documents I file an the federal safety agency complaint. What occurs when the vehicle is not in warranty and the vehicle continues to shudder. I have included the service bulletin and repair invoices.
Transmission shuddering shaking almost stopping with 60,292 miles used
Drive ability issues, feels like going over cattle guard,shudders when accelerating around 40-60 mph. the vehicle shudder's abnormally. there are no warning lights illuminated. Took to local Chevrolet dealership where a service bulletin, TSB: 21-NA-047 was discovered to address the issue. The dealer recommended a transmission fluid flush. Mileage on this vehicle was 67,631.
No warning lights are illuminated but have this consistent violent Engine rattle/shuddering that is getting worse and worse. Also when looking under the hood the Crank pulley wobbles/rattles when truck is idle. Was told it could be the harmonic balancer going out due to there being a gap between that and the Crank. The truck only has 100,000 miles on it. I got it used at 88,000 miles and have barely had the truck for a year now, the steering wheel was intermittently difficult to maneuver and no warning lights illuminate, the truck shifts hard from 1st to second gear now and seriously hesitates to accelerate. This is extremely concerning and apparently an ongoing complaint for this vehicle and something should be done about it. Not only does it cause financial destress on the owners of the vehicles but also a safety hazard to the driver
COMPLAINT # 11630574 Transmission Shudder, took to dealership on 09/28/2023 had transmission flushed and changed fluid to new style transmission fluid, per GM under warranty. I was told that if it needed done again that i would have to pay to have it done and would cost approximately $400- $500. On 12/13/2024 the truck is shuddering again at 48,700 miles.
The contact owns a 2020 Chevrolet Colorado. The contact stated while driving 30-50 MPH, the vehicle shuddered abnormally. There were no warning lights illuminated. The vehicle was taken to the local dealer to be diagnosed and the dealer became aware that the vehicle was shuddering at 35 MPH. The dealer recommended a transmission fluid flush and refill. The vehicle was not repaired. The manufacturer was contacted and referred the contact to the federal safety agency Hotline. The contact was also made aware of TSB: 21-NA-047. The approximate failure mileage was 56,000.
The Automatic 8-Speed Transmission completely deteriorated after 4 years/64,000 miles exactly after the Power Train Warranty. No warning lights or signals identified me of the problem, only a noticeable shuddering when driving at highway speeds. This vehicle is currently at the dealership where they have confirmed I will need a new transmission to replace the faulty original manufacturer's transmission. My safety and others' safety is/was affected by a faulty piece of equipment that was destroyed with regular use. This could potentially lead to my vehicle being unable to shift up/down during traffic leading to an injury or worse.
A transmission shudder has developed. It seems to be a known issue that Chevrolet has tried to resolve, but it is present in my vehicle. It started to develop around 60,000 miles ago and has progressively gotten worse.
Transmission shudder unless I put vehicle in tow haul. Shudders at a out 35 40 miles per hour. Seems to be a recurring problem from 2018 forward. This vehicle has only about 25 000 miles on it. I researched and also spike to a transmission person and they think it may be a computer issue. Supposedly they replace transmission fluid if that doesn't fix they replace took convertor. The problem I have is this is a long time recurring problem that should be identified and fixed by General Motors. A vehicle with such low miles built 2 years after they are aware these transmissions have the what's called dreaded shudder shouldn't still be happening.
Like the 2017-2019 Chevrolet Colorados my 2020 Colorado also has transmission shudders from time to time and I get random vibrations
