2019 Chevrolet Silverado 1500: transmission slipping

Filed Aug 11, 2026 · Engine, Fuel system · TX

I am reporting a potential safety defect involving my 2019 Chevrolet Silverado 1500 Z71 Trail Boss (VIN [XXX]), currently at approximately 63,000 miles. My truck suddenly developed a rough idle, engine ticking, and a cylinder 3 misfire. The check engine, traction control, parking brake, and “Service ESC” warnings appeared. The transmission also began shifting extremely hard, at times feeling as though another vehicle had struck the truck from behind. The oil pressure gauge also stopped functioning. Due to these symptoms, I stopped driving the vehicle. A diagnostic scan produced P0303, P0449, P0498, P0499 and P0500. After replacing a failed cylinder 3 spark plug, the truck initially ran perfectly for approximately 20 minutes before the rough idle and warning lights returned. The vehicle was subsequently diagnosed by a Chevrolet dealership. The dealership determined that the engine suffered a collapsed lifter that damaged the camshaft and other internal engine components. The engine repair estimate is approximately $10,000–$12,000. The dealership has also reported that the transmission is slipping and believes the torque converter/transmission requires approximately another $6,300 in repairs. I am concerned that a lifter/DFM-related failure causing a misfire, rough running and potential loss of engine power could occur while a vehicle is traveling at highway speed and create a significant safety hazard. The severe transmission shifting and subsequent slipping are also concerning because unexpected vehicle behavior during acceleration or while in traffic could increase the risk of a crash. The truck has been regularly maintained and has relatively low mileage for its age. I am requesting that the federal safety agency review whether similar engine/lifter/DFM and related powertrain failures represent a broader safety defect and whether an investigation or recall is warranted.

I own a 2019 Chevrolet Silverado 1500 equipped with the 8-speed automatic transmission. The vehicle has developed serious transmission problems that create a safety concern. When the transmission is cold, the vehicle slips between 1st and 2nd gear during acceleration. If I accelerate normally, the transmission slips and then engages with a hard bang. I must accelerate very slowly to avoid harsh engagement. In addition, during deceleration, especially when downshifting into 3rd gear, the transmission makes a hard "thump" or "bang". This unexpected shifting behavior creates a safety risk when entering traffic, making turns, or driving in stop-and-go traffic. The vehicle has been properly maintained, including transmission fluid service at a Chevrolet dealership, but the problem continues and appears to be getting worse. I understand many GM 8-speed transmission owners have reported similar issues. The repair cost quoted by the dealership is between $7,000 and $10,000, which suggests a possible design or manufacturing defect. I am filing this complaint for investigation of a potential safety-related transmission defect.

The 8-speed transmission has been a problem from day 1 of owning this truck. It has a bad vibration, slips into gear and hard shifts. I have maintained this truck to the fullest and have done all service to the fluids as requested by the manufacturer. I have never pulled a trailer, and I want The NTHSA to make all Chevrolet products that have this 8-speed transmission recalled. GM should make this right. These vehicles aren't cheap.

I have a 2019 Chevrolet Silverado 1500 LT and I am having issues with the transmission bucking, hesitating, slipping. I am also having issues with the variable timing system. The variable timing system started acting up last year and when I took it to the dealer they replaced it and I was charged over $400 for it to be repaired. It happened again the beginning of this year and I took it back to the dealer. They told me the oil was dirty and suggested an oil change to fix the issue. I had the oil change done and now I am having the same problem again and have already had the oil changed. I need help since I am paying for a vehicle that is sitting in my driveway not being able to be used. There are 6 codes that have popped up including the variable timing system, cylinder 4 misfire, brake system, and I'm not exactly sure what the other ones are.

Transmission slips going into 1st. Then when it shifts to the next gears it shudders. It is available for inspection but I have not taken it to a service center. No lamps and messages are present.

When I bought the truck it only had 82 miles on it. After owning it for about a month it was shifting very hard at times. So hard it felt like I was being hit from behind. I complained to the dealership and they told me "that's normal for those". I learned how to drive it to avoid the problem. At 52000 miles I had the dealership do the routine transmission service that is due @ 45,000. The truck was fine when I took it in. When I got it back it was shifting extremely hard and erratically. It would downshift and accelerate by itself. On wet roads it would fishtail and I would almost lose control. It did this in traffic and I almost slid into oncoming traffic. While pulling away from a stop sign, the transmission slipped so bad the engine revved to 5000 rpm before catching. Then the check engine light came on. I took the truck to the dealership the next morning and they checked it out. They said it needs a new transmission. They also said it was my fault for going past the recommended service interval by 14%. Now they say a new transmission is going to cost $12,582.78. GM has agreed to pay half of that but they have known about these transmissions for years and they kept selling them anyway. My truck was not showing any unusual signs that the transmission was failing until I got it back from the dealership after they serviced it.

Transmission slips, into 2nd i believe. Hard shifts, shuddering and shaking at intermittent speeds. Also missed shifts and dtc triggered in performance mode. Started happening last year, 2023, progressively becoming worse overtime. Last summer is when it didn't shift and set off multiple codes that had to be cleared to be able to operate normally. Dealership stated since codes had been cleared they couldn't do anything about it, so nothing was done. (I can still find the codes with my personal code tool)

Transmission started slipping and shuddering on vehicle with only 72,000 miles. Took to the dealer and they diagnosed the transmission fluid and torque converter needed to be replaced. The vehicle experienced harsh shifting since new and is a safety issue due to delayed speed, slipping, and hard shifts. There is a class action lawsuit for this 8 speed transmission and GM refuses to fix it. I paid $3,000 out of pocket to have this fixed even though it’s a known. Issue.

Since Purchasing the vehicle, I have taken it to the dealership due to the transmission feels like it is slipping or buckling and not wanting to shift each time they told me there is no issue with the vehicle. This vehicle was purchased in 2019 and has a little over 22 k miles.
