2016 Chevrolet Silverado 1500 transmission problems

Filed Oct 13, 2026 · Transmission · IA

Vehicle: 2016 Chevrolet Silverado 1500 Component: Powertrain – Automatic Transmission (8L90) Manufacturer: General Motors (Chevrolet) I am submitting this complaint regarding recurring transmission problems with my 2016 Chevrolet Silverado 1500 equipped with the GM 8L90 eight-speed automatic transmission. I am concerned about the vehicle's inconsistent shifting behavior, the repeated failure to resolve these issues through service, and the potential safety implications of unpredictable transmission performance. My truck has been taken into the shop multiple times because of transmission-related concerns, including hard shifting, intermittent and inconsistent shifting, and transmission shudder. Despite these repeated service visits, the problems have continued. During one of the repair visits, the transmission wiring harness was replaced. However, the shifting concerns persisted. I was subsequently told by the service personnel that the hard shifting and intermittent shifting were “just how the transmissions on these are.” I do not consider this an acceptable resolution to a recurring mechanical and drivability concern. I was also informed that GM introduced updated transmission fluid intended to help address the transmission shudder, but that I would have to pay for the fluid service myself. I have been left facing additional expenses for the revised fluid, a potential torque converter replacement, and other transmission upgrades despite the repeated repair attempts and the continued existence of these problems. My primary concern is the transmission's inconsistent operation and the possibility that unexpected or severe shifting behavior could affect the driver's ability to control the vehicle safely in certain driving situations. Depending on the circumstances, unpredictable shifting, hesitation, or abrupt engagement could create a hazardous situation when accelerating, merging into traffic, navigating intersections, or driving in congested condition

"While driving, the vehicle experienced a sudden and complete loss of propulsion/acceleration due to internal failure of the 6L80 6-speed automatic transmission. The failure occurred without prior warning, creating an immediate highway safety hazard by leaving the vehicle unable to maintain speed in traffic. A professional mechanic diagnosed the issue as a catastrophic torque converter failure that contaminated the entire transmission system with metal debris, requiring a complete out-of-pocket rebuild." This resulted in having to pay $4,800 plus tax in such a rough economy.

I had noticed that my a/c was not cooling due to refrigerant loss. went to dealer and was told that I needed a new condenser and that my original was out of warranty & no recall was in effect. I was charged $1600.00 after the replacement was installed. I asked to see my original condenser & was directed behind the shop & low & behold there was a pile of 30 condensers exactly identical to mine

Transmission started shifting hard, shuddering in torque converter, and long time shifting into 1st gear. Took it to a Transmission guy and he said it needs a full rebuild and is very common with this Transmission in this truck.
