Chevrolet Silverado 1500 won't shift problems

Filed Nov 5, 2026 · Transmission · OH

The truck has a serious transmission issue where it either will not shift into gear or gets stuck in a gear. I’ve had several instances on the freeway in traffic where this happens and I’m unable to keep up with the flow of traffic and feared another vehicle would not be able to avoid a collision. I need to exit the freeway and turn the car off for it to reset. But it will often just do this failure again. It creates a very dangerous situation. GM is aware of this, and offered a special warranty repair, but for some reason they refuse to honor the warranty for my truck

While driving home from work, I pulled up to the stop sign at the end of the exit ramp. When I released the brake and pressed the gas pedal, my truck would not move. This immediately put me in an anxious state as I was expecting the vehicle to move. I checked my rearview mirror to make sure that there wasn’t anybody coming up behind me and put my flashers on while I tried to figure out what was going on. My eyes moved to the shifter next. I noticed that the vehicle was in park. I reached down to the shifter and tried to put the vehicle in drive, but it would not shift. I then hit the push-to-start button to restart the vehicle. After this, I was able to shift back into drive and finish my commute home. This was an unsafe condition as I experienced an unexpected loss of power. An approaching vehicle would expect me to be moving when the road is clear in front of me. I took the truck to the dealership the next day. My vehicle was repaired under warranty. The cause states "update 2810275 Serial Data Gateway Module Reprogramming with SPS." I did not notice any warning lamps or messages, but I also did not look at the instrument panel when this happened. My first thought was to check for approaching vehicle traffic and to put on my flashers. After I put on my flashers, I looked down and noticed the vehicle was in park.

The vehicle is experiencing gear shifting failure. Specifically, when the transmission temperature reaches over 160 degrees, it shifts into limp mode and loses power, which creates a significant collision risk. Additionally, the forward collision warning system is not working at all.

I drive a 2023 Chevrolet Silverado 1500 3.0L Diesel with the 10-speed transmission. The transmission control software failed to monitor/detect valve body wear or trigger a 5th-gear 'limp mode' safety net, resulting in three separate instances of sudden rear-wheel lockup at speed. The dealer was unable to replicate the issue during a service visit from 6/10 - XXX. The issue was raised as the transmission was shifting increasingly badly leading up to this service visit. The first full lockup occurred a few days after receipt of the vehicle on XXX driving eastbound on [XXX]. Off the gas, coasting downhill. Once everybody started speeding up, I increased the throttle gently and the truck shook violently. I initially thought I had been hit by another vehicle but realized it was the transmission. Speed was noted 24 mph. The second incident occurred XXX while traveling to [XXX]. Driving southbound between [XXX] and [XXX] at approximately 50 MPH in a coasting condition. Went to pass a slow vehicle and the vehicle jerked violently an locked the rear wheels. Initial assumption was that I had been hit. Was able to regain control and continue. The third incident occurredXXX while traveling from [XXX] to [XXX]. Driving eastbound on [XXX] at approximately 35 mph, when moving from a coast to acceleration posture, the vehicle again locked the rear wheels and jerked violently. Finally, onXXX when traveling southbound from [XXX] to [XXX], I stopped for fuel. When attempting to accelerate onto the freeway, the vehicle failed to engage 6 gear, stumbled, and then went into limp mode with a check engine light. On XXX a [XXX] dealer found code P0747 and addressed the issue with [XXX]. I was forced to rent a car to continue my journey to [XXX]. GM ultimately shipped my truck back to me one week later. The software 'fix' clearly did not work as intended and remains a serious safety hazard. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Around 60k miles my truck started shifting rough and at odd times. Then it went into “limp” mode. I took it to the dealership and they replaced my battery and a solenoid. I asked about the transmission and they told me it was because it was in “limp mode”. I’ve continued to have issues with it then a couple of months ago while driving to work at around 60mph the truck harshly downshifted into a low gear causing the rear tires to break loose on the wet roads and sending me into an extended spin. I had the truck towed home and then to the local dealership. After researching, I have found that this is very common with the same vehicles in this year and that there are multiple recalls to address the issues. Unfortunately my VIN is not included. I believe the needed repairs and the associated costs should be GM’s responsibility under special coverages: N242454441 and N242454440-03

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated that the vehicle had been experiencing inaccurate DEF gauge readings since the purchase, and the failure mostly occurred while towing a camper or trailer. The contact stated that while driving 70 MPH on the highway and hauling a camper, the message that the DEF tank was empty and needed to be refilled was displayed, and the vehicle went into LIMP Mode and decelerated to 35 MPH. The driver continued driving and pulled over to a safe location. The vehicle was taken to a dealer, where it was determined that the DEF tank needed to be replaced; however, the manufacturer denied authorization because the required preliminary procedures had not been completed. The manufacturer General Motors LLC was notified of the failure by phone. The failure mileage was approximately 4.
