Third transmission failure in 10 months on this vehicle (8-speed automatic). (1) Oct 2025, 67,885 miles: transmission shuddering; dealer replaced the complete transmission with a GM remanufactured unit under extended warranty (RO 240481, Nucar Lannan Chevrolet of Woburn, MA). (2) Jul 2026, 82,439 miles: vehicle would not shift on the highway while driving; DTC P2824 stored; dealer replaced the transmission valve body under warranty (RO 248929). (3) Aug 3, 2026, approx. 82,500 miles — three days after the valve body repair was returned to me — the transmission locked up and the vehicle would not shift gears while in traffic. Loss of gear engagement while driving creates risk of a crash from sudden loss of propulsion. Vehicle is back at the dealership now for the third repair. This vehicle's 8-speed transmission (8L90/8L45 family) is the subject of known shudder/valve-body defect litigation covering 2015–2019 Silverado models.

What component or system failed or malfunctioned, and is it available for inspection upon request? The transmission and drivetrain system appear to be defective. The vehicle repeatedly experiences hard shifting, transmission shudder, hesitation during acceleration, delayed engagement when shifting into gear, and erratic gear changes. These problems occur during normal driving and have progressively worsened over time. The vehicle is available for inspection upon request. How was your safety or the safety of others put at risk? The transmission hesitation and delayed acceleration create a serious safety hazard. When pulling into traffic, crossing intersections, or changing lanes, the vehicle does not respond immediately when the accelerator is pressed. The delay leaves the vehicle exposed to oncoming traffic and increases the risk of a collision. The hard shifting and shuddering also cause the vehicle to behave unpredictably, reducing driver confidence and making it unsafe to operate in normal traffic conditions. Has the problem been reproduced or confirmed by a dealer or independent service center? The problem is consistently reproducible during everyday driving. The transmission shudders, hesitates, and shifts harshly on a regular basis. Although the condition is intermittent in severity, it occurs frequently enough to create ongoing safety concerns. At this time, the vehicle has not been inspected by police or insurance representatives. The vehicle remains available for inspection. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? The first symptoms were occasional hard shifts and slight hesitation during acceleration. Over time, the condition worsened, progressing to severe shuddering, delayed acceleration, and increasingly harsh gear changes. No warning lights or diagnostic messages appeared when the symptoms first began, making it difficult to identify the problem before it be

I am filing this complaint to report a critical manufacturing safety defect regarding the rear differential in my 2019 Chevrolet Silverado 1500. During a recent dealership inspection at approximately 40,400 miles, an authorized GM service center (Jack Hanania Chevrolet) discovered that the vehicle's rear differential was completely "bone dry" of gear oil . Because there is no history of catastrophic fluid leaks, seal blowouts, or external damage, this strongly indicates that the rear differential was either never filled or improperly filled with lubricant at the factory during vehicle assembly. This issue originally presented as a persistent drivetrain vibration, shudder, and "skipping" sensation starting as early as 12,000 miles . I brought the vehicle to the dealership for this exact vibration at approximately 21,000 miles. The dealership misdiagnosed the issue as "low transmission fluid" (despite the transmission being a sealed system) and failed to inspect the rear differential . The symptoms persisted until the vehicle was immobilized in November 2025, which is when the bone-dry rear differential was finally discovered . A vehicle operating with an empty rear differential poses an extreme and immediate safety hazard. The lack of lubrication causes severe internal heat and friction, inevitably leading to a sudden, catastrophic mechanical seizure of the rear axle . If the rear wheels lock up while driving at highway speeds, it will cause an immediate loss of vehicle control, resulting in a high-speed collision. I urge the federal safety agency to investigate GM's factory fluid-fill procedures and quality control for 2019 Silverado differentials to prevent a fatal lock-up event for other drivers on the road.

My 2019 vehicle experienced premature torque converter failure resulting in transmission shuddering, hesitation, and loss of power while driving. The transmission fluid was found to be burnt, and the vehicle requires major transmission repair. These symptoms occurred during normal driving conditions and created a safety concern due to unpredictable vehicle behavior, particularly during acceleration and merging. This issue is widely reported in 2019 vehicles equipped with GM 8-speed transmissions. GM has acknowledged the issue through technical service bulletins but has not issued a recall.

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. 55

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.
