The valve body for the transmission failed. While driving the vehicle transmission would shift violently. This would cause the truck to jerk forward a few times before engaging the next gear. At times it caused a slowed performance and could have caused an accident with another motor vehicle especially when traveling uphill. I brought the truck to a chevrolet dealership and they confirmed this issue. I also completed online forum and general searches through google which confirm this is an issue especially with the 4 cylinder and v6 engines. The check engine light came on when the issue first occurred. The issue happened a week after my catalytic converter was replaced under warranty in July 2025.

Passenger side lifters have failed, along with camshaft. The induced misfire caused a sudden and potentially unsafe jerking of the vehicle while on the expressway. The vehicle was on cruise control and running at 1,400rpms at the time of the failure. There were zero warning lights or vibrations/noises that could have indicated an imminent failure. Thankfully I was alone on the expressway at the time of the incident as the vehicle started bucking, jerking me out of my lane until I could regain control. Vehicle had 105,500 miles with all engine maintenance up to date prior to incident. Speed limit on this section of US31 is 75mph.

GM says my Vin was not part of the recalls, The Vin wasn't the problem, It was the Transmission!!! letter I sent to GM : Transmission Failure on 2019 Chevrolet Silverado 1500 LT Dear General Motors Customer Assistance, I am writing to formally express my concern regarding the complete failure of the 8L90 transmission in my 2019 Chevrolet Silverado 1500 LT. I have been a loyal Chevrolet customer and have always trusted GM vehicles for their reliability and performance. However, the recent catastrophic failure of my transmission-?"resulting in both internal and external damage-?"has left me extremely disappointed and financially burdened. This vehicle, equipped with the 8-speed 8L90 transmission, began exhibiting harsh shifting, delayed acceleration, and shuddering well before the failure. Despite regular maintenance and proper care, the transmission ultimately failed and "blew up" both internally and externally, rendering the vehicle undrivable and in need of complete transmission replacement. Upon further research, I discovered that numerous owners of 2015-?"2019 GM vehicles with the 8L90 transmission have reported similar issues, and multiple class-action lawsuits have been filed citing systemic defects in this transmission design. Though no recall has been officially issued, the volume of complaints and the existence of internal Technical Service Bulletins (such as TSB 16-NA-019) suggest GM is aware of the ongoing problems associated with this transmission. Given these circumstances, I am requesting that General Motors stand behind its product and assist with the full cost of replacing the failed transmission. I am prepared to provide documentation including service records, a technician-??s report on the failure, and photos of the damage if needed. Please let me know how GM intends to proceed with this request. I would appreciate a prompt and fair resolution to this matter. Sincerely, [XXX] VIN # [XXX] Current Mileage: 114850 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C.

I am experiencing the exact details of N192272400 Rear Wheels Lock At Low Speed but for some reason my VIN isn-??t associated with the recall! This is highly dangerous. It could cause a serious accident seen that I live on a main road. I don-??t know where the vehicle locks up the rear brakes if I go over 5 miles an hour at random times. I believe 100% that it is exactly what is described in that recall which is a defective TCM that has a short circuit. Another issue that I have with his truck out of nowhere is a short circuit in my rear defroster that was sparking and smoking when I used it.

During acceleration my vehicle had a whinning noise coming from near the transmission. It will buck and then when slowing down to a stop it bucks like being hit in the rear by another vehicle. It also shudders and makes the reduce engine power light come on.

- Jaffrey, NH, USA

Bought my truck with 29,000 miles on it. Was making a noise in rear tire. Took it in and it was the break calilper. Dealership wanted $1500 to replace it a week after I bought it. Stated that it was not covered. After a week of arguing, they did not charge me for it. Around 40,000 miles, every once in a while, it would feel like I was being rear ended when I came to a stop. It was not often, but around 55,000 miles, was more frequent. I took it to the dealershp at 62,000 miles and they said that it was a torque converter and would not be covered. Fixed it at a shop $2700. Lifter and Cam in the UP of michigan $5000. Oil lines at 110,000 $700. Torque converter again at 130000, and now lifter and camshaft again at 145,000 miles. I feel that GM should back their product. I had a 95 Chevy Silverado that I sold with 360,000 miles and never had any issues except fot transmission at 250,000 which is expected. I have all receipts showing proof

What component or system failed or malfunctioned, and is it available for inspection upon request" The 8-speed automatic transmission is experiencing a persistent shudder during normal driving conditions. The problem appears to stem from a failing torque converter and possibly the valve body, as diagnosed by a GM dealership. The dealership also found metal debris in the transmission fluid, indicating internal damage. The vehicle is currently available for inspection upon request. How was your safety or the safety of others put at risk? The transmission shudder causes the vehicle to hesitate and lurch unexpectedly, especially during acceleration or gear shifts at highway speeds. This creates unpredictable vehicle behavior that could result in a loss of control, especially when merging, changing lanes, or driving in heavy traffic. It presents a significant safety concern for both the driver and others on the road. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the problem has been confirmed by a GM dealership. They recommended replacing the torque converter and valve body due to internal damage and fluid contamination. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes, the vehicle has been inspected and diagnosed by a GM-authorized dealership. It has not been inspected by police or insurance representatives. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear" No warning lamps or dashboard messages appeared. The issue began with a noticeable shuddering and harsh shifting during normal driving, which gradually worsened. Symptoms include rough gear changes, hesitation, and vibration, most noticeable between 25-?"55 mph under light acceleration. These symptoms began approximately 2 months ago and have become more frequent.

Since I have owned this vehicle I have experienced erratic shifting, primarily when driving in traffic, and when the vehicle is downshifting to 1st or 2nd gear. It has occasionally occurred when traveling on the highway during an upshift, but this is rare. I have also experienced lurching when stopped, or creeping forward in anticipation of a turn. I can occur at any time, and under any type of conditions, hot or cold. It also has a tendency to shift harshly when shifting from park to reverse or from reverse to drive. I have expressed my concerns with my dealer, and it appears they are aware of the problem, and have told me that GM is also aware of the issue, but they dismiss it by way of saying it is normal. I have had the transmission fluid changed at the regular interval, but this has not cured the problem. Finally, GM is well aware of this issue, and is subject to class action lawsuit regarding these transmissions, and other owners have stated that they too have experienced this shifting issue. My concern is that this will eventually lead to a failure of the transmission and the drive components i.e., drive shaft, pinon gear, differential housing, anything connected to the transmission. If this failure occurs at highway speeds, a possible loss of control and crash could occur.

Truck has been making a clunking sound for over a year and has gotten worse. Recently took to Jim-??s Transmission to have transmission evaluated. Have been told that transmission needs to have a rebuild or new transmission $4500-6000. The truck has just over 67000 miles on it. Understand that there are class action suits regarding Gm being aware of the flaw in the transmissions. I have contacted both Chevy dealer and GM via certified letter and GM via email, and received no response regarding a goodwill repair.

I was driving on the highway at a speed of around 65 miles an hour and I heard a loud noise and the truck did a hard jerk and slowed down abruptly I then had to struggle to get over to the shoulder as cars around me were moving at high speeds then I found out that it was the lifters that failed and I started doing research on this problem and it seems to be a problem that a lot of people are having with these trucks as well as transmission issues which I was having before this happened
