Filed Oct 20, 2026 · Transmission · TN

Transmission started slipping for no reason around 100 thousand miles. All maintenance had been done no code was ever shown on dash no check engine light took it to 3 different places and had it tested all said the same thing they couldn't find anything wrong. Now its sitting at the shop and they are saying its the Transmission and it needs a new one.

Transmission failed before 100,000 miles. All service was complete throughout the life of the vehicle. Problems shifting to next gear causing pulling or slipping on the vehicle. If not able to accelerate properly could cause a safety concern on the road. Repairs were made costing $9,000.

The Timing Chain failed. It is at the Dealership available for inspection. Vehicle was unable to accelerate correctly while driving. If it had blown a valve or locked up the engine we would have been stuck on the highway with my kids in the vehicle. Problem has been confirmed with the dealer. It is a known defect with this vehicle but my VIN was not one that was recalled. No issues had came up before it failed. Just went to accelerate and you could feel it slipping and the truck stuttering forward.

On Sunday Nov. 16th, my steering wheel felt like it was "slipping", akin to how it feels when your serpentine belt tensioner is failing. I checked it out while wife turned the wheel, didn't see any problem, and we went on our way. Later in the day as we were leaving a parking lot, the problem occurred again but worse. And we got a warning about trailer brake controller needs repair. After reviewing similar problems on Reddit, I found it was still safe to drive, so we drove home without further incident. Monday I decided to take it to O'Reilly auto parts and have a code scan done. Except, as soon as I turned out of the driveway, my wheel completely froze up solid. I could NOT move the wheel (q2)! Since the wheel was still turned, I backed it into the driveway and we took our car to buy our own code scanner. It showed more than just one fault code for the brakes, there were 5. I called Fox Chevrolet to schedule al appointment for the next day. Fortunately, the failure occurred as the Advisor attempted to turn the wheel (q3). Long story short: problem was a rusted/rotted out ground wire (q1)! Behind the front driver side tire, encased in a boot. Tech told the Advisor he'd never seen that one before. $40 part, and $400 to install it (q4). I was happy it wasn't a power steering rack failure (electric) but the more I thought about it, felt I needed to report this. You needed a dealer scanner to catch this and trace it to a ground fault. Probably better for you to contact dealer Advisor and Tech to get a better breakdown on this (q1). Dealer was great, they could have sold me an $1800 steering rack and I'd have never known. Could this failure have happened to someone driving on the street and this pop up all of a sudden (q2)? I believe so. Glad I didn't find out firsthand. The problem went away overnight twice, and then all of a sudden your wheel is LOCKED. I'm curious as to if others are or have faced this, thus my submittal. Thanks for your time.

The transmission has been slipping and shuttering which shouldn’t be an issue at 119,000 miles. This opposed a huge safety risk for me and my girlfriend on the highway. I was driving and it shuttered so bad i had thought the wheel was loose and coming off. I had to pull over on the highway to check the lugs and came to find out it’s the transmission, because it shuttered numerous times after. On top of that the entire trip was the transmission shuddering slightly making the wheels cut the the left and right. But throughout the trip, it had a slight shutter the entire time and a couple of big shutters, and one very large shutter that had my girlfriend think I ran over a bunch of wood in the road resulting in me pulling over being in danger and possibly wrecking from the shaking, and having to exit my truck on the side of the highway with 18 wheelers and other vehicles flying at 80+ miles an hour. Besides the safety issue, there should be no reason for these transmission going out like this at 60k miles and 100k miles it’s extremely cheap of GM and a huge hazard to many families.

Transmission slips, jerks, delayed shifting symptoms consistent with technical service bulletins and known recalls on later models. Add that it was purchased new and is still financed

Component/system that failed: The transmission control module in my 2020 Chevrolet Silverado 1500 has malfunctioned. The vehicle has issues with slipping between gears, rough shifting, and hesitation when accelerating. This component has already been inspected and diagnosed by a certified Chevrolet dealership, and the part is currently on backorder. The vehicle is available for further inspection upon request. Safety risk: This issue poses a serious safety risk to myself and others. The gear slipping and delayed response when driving—especially when merging onto highways or changing lanes—creates unpredictable behavior that can lead to an accident. The truck sometimes fails to engage gears properly, which makes it dangerous in traffic situations. Diagnosis confirmation: Yes, the problem has been confirmed by a Chevy dealership service advisor (Jose Diaz), who provided a formal quote and diagnosis for the replacement of the transmission control module. Inspection by others: The vehicle has not been inspected by police or insurance representatives, but Chevrolet Customer Assistance is currently reviewing the case, and I was advised to submit this documentation. Warning lamps or symptoms: There were no warning lamps initially, Symptoms include slipping gears, hesitation when pressing the gas pedal, jerky shifting, and difficulty accelerating smoothly. These symptoms have progressively worsened over time. Additional context: I have learned that many 2020 Chevrolet Silverado trucks have been recalled for the exact same issue, but my VIN is currently not included. I believe this is a manufacturing defect and that my vehicle should be considered for inclusion in the recall or further investigation.

torque converter and transmission. For more than a year truck would lunge or jump forward when stopped at light or sitting in traffic, brought truck back to dealer several times for this problem each time they would tell me nothing wrong with truck. problems continued to happen and Truck started hesitating when accelerating then jumping into gear also while driving on highway truck felt like it was slipping out of gear and RPMs would jump up. Brought truck back to dealer again 3 months ago and they said torque converter was going bad and they would call me when part was in. two months later and they kept saying it was back ordered, now while driving going down steep incline into busy intersection felt like i got rear ended by another car, when looking back no car was close me truck stalled and started rolling into intersection I slammed on brake and got truck started again only to find transmission had failed and it slammed into gear when accelerating put my flashers on and got off road . Brought truck back to dealer to have them tell me transmission was now gone. truck has now been sitting on dealer lot for a month now with them telling me they can't get parts or transmission to fix. Very dangerous situation with this transmission and them knowingly kept sending me away in this truck. I feel that they knew about transmission problem over a year ago when I was bringing it in for the lunging forward after coming to complete stop at traffic light and kept saying nothing wrong. Truck was still under original warranty and only has 62k miles on truck.
