While on the Interstate with cruise control on, my truck started to vibrate while on highway, then shakes so badly it becomes difficult to grip steering wheel firmly. Slowly came to a stop and checked all four wheels. Waited on side of road until engine cooled down somewhat and then got off highway at next exit and made my way back home on side streets NOT DRIVING OVER 40-45 MPH. Vehicle is currently at dealer Service Department. Said it is normal, but transmission would be checked.

My 10 speed transmission is failing, problem is a shutter in the transmission at various speeds. Have the shutter verified as not wheel balance problem, as all wheels were spin balanced. Upon looking up info online they said it could be dangerious and cause an accident.... My 2018 Silverado with the 6.0 engine and 10 speed transmision has only 42,000 thousand miles on it...

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated that while driving approximately 64 MPH with the cruise control engaged, the transmission became inoperable. While going up a hill, the vehicle was shifting hard in first and second gear. Upon accelerating, there was an abnormal winding noise detected. The vehicle was shifting roughly. The transmission got up to 160 degrees and continued to shift hard. There were no warning lights illuminated. The vehicle was taken to the local dealer where it was diagnosed that a transmission replacement was needed. The vehicle was not repaired. The manufacturer was contacted and informed him that the vehicle was above the warranty mileage. The failure mileage was approximately 96,000.

Torque converter was broken and destroyed my transmission just at 90,000 miles. I could easily have been stranded in major city traffic at any point if this had failed any earlier. This problem has been known in various GMC vehicles throughout the years. I have had a mechanic inspect and diagnose this problem. No warnings or symptoms were seen prior to the full failure of my transmission.

Transmission doesn-??t shift smoothly and often slams into second gear from first very hard. Downshifting on rare occasions shifts to a lower gear before necessary causing rpms to go from 2800-3000 up to 4500-5000. I have to touch the gas real quick to upshift. Also brakes seem to require extra strength to engage if hard braking is required. Like the booster is not reacting properly.

The truck has has multiple issues.RR taillight always blows fuse, which I think sometimes stops my back sliding glass, I have no power to it, this has been an issue since day one, always have to carry fuses, then not long after having the truck, it has stabili trak issues, it stalls when first put into drive.delayed take off sometimes the truck jumps forward and revs the rpm-??s up to 1000 X rpm sitting then it jumps to a fast hard takeoff.the truck does something called chuggel and buck I believe, it bogs way down, and then again it-??ll slip buck it kicks jerks and also harshly engages.I love Chevy and haven-??t given up hope just yet.this is my first Chevy.

Motor vehicle accident 4/21/22. Vehicle stalled hit by 18 wheeler. Several times on several occasions after that on several days vehicle stalled in interstates with multiple 18 wheelers, trucks cars almost hitting me/my vehicle each time it stalled. Now and since May 2022, the transmission completely failed and is inoperable at this time. The stalling in the middle of interstate traffic where the speed limit on 4/21/22 is 55mph & on the interstate 65mph(The vehicle coasted slowly to the side of the road & stopped changing gears to go in either direction)

Transmission issues with 78500 miles, one owner, no hauling other than a boat. headed to shop... multiple complaints on 2018 transmissions why no recall

- Mccordsville, IN, USA

Under light to medium load on the throttle, the transmission will shift very hard from 1st to 2nd gear and sometimes 2nd to 1st while decelerating. Another issue is that the transmission or torque converter will shutter, but that is not as often. It does not happen every time, but happens way more often than it should for it being a 2018 with 26k miles. The GM Authority website has this as a known problem, but my VIN is not associated to it for some reason. Apparently flushing the transmission with Mobil 1 Synchromesh fluid can solve the issue. The truck seems to hesitate while taking off something and I think it is related to this transmission issue which can be a huge safety risk.

On Saturday Aug 6th, 2022 my girlfriend and I were driving in my 2018 Chevy Silverado and the car just came to a complete stop really hard. Once the truck froze up, the car would go FOWARD but very slow, jerkish, and sluggish. We were almost hit by three cars behind us when the truck froze up. The truck was towed to the dealership where they diagnosed the truck with METAL SHAVINGS in the TRANSMISSION. And the engine light came on four weeks after I bought the vehicle last October. This time-??. There was NO engine light on. Nothing displayed on dashboard.

- Faurfield, CA, USA

The transmission failed at 81k miles. Upon doing some research, it sounds like this is caused by the wrong transmission fluid that was installed by GM, not myself, the owner. If known about early enough, flushing the transmission 3 times and replacing with the newest transmission fluid is to correct the problem. I was not notified of this 'fix' and the transmission is already damaged to the point where it must be replaced.

The transmission failed. The truck had heavy shifting and the transmission needs replacement. The truck was no longer safe to drive. The problem was diagnosed by a licensed mechanic shop. The check engine light came on as well as the service stabilitrak light that came on the same day as failure.

For months this truck as stuttered while driving. Eventually one day the RPMs would shoot to 3500 when trying to shift gears and would struggle to shift. After having the spark plugs replaced and a tune up ($660 later) it started randomly just losing power to the engine while driving. All electrical still on but no power to the engine. I would pull over and turn the engine off and restart and it would be fine again. This continues to happen with no explanation. Always acts fine after I stop the care and turn it back on again. Nothing comes up on a scan for issues. Mechanic can't figure it out and now it isn't "acting up" when the transmission guy drives it and he doesn't know what's going on either. It's not safe to drive on the HW if its going to just randomly lose power. We checked with another transmission shop and he said they have two chevy Silverados in line for something similar. That made me look to see if there was a recall and led me to make this report. Chevy should look into this and do a recall.

Transmission shifts out of gear spontaneously while driving and warning light comes on for -??transmission hot idle engine-?? forcing the vehicle to become inoperable unexpectedly without allowing the vehicle to drive forward or reverse to get to a safe location. Transmission temperature gauge rises quickly to 280 degrees in less than an hour of normal driving before overheating. Multiple General Motors dealers and General Motors headquarters have been unable to diagnose the problem and provide a solution despite multiple attempts and several thousand dollars in repairs including a completely new replacement transmission. General Motors first recommended the dealer to hook battery cables up to the transmission which did not fix the problem and in fact caused the vehicle to not start several times. General Motors then recommended the dealer replace the transmission entirely. Despite replacing the transmission, the same problem exists and the vehicle shifts out of gear while driving reporting an overheating transmission. Problem still occurs today 3/25/22 and vehicle becomes inoperable unexpectedly and suddenly while driving due to overheating transmission. General Motors is unable to diagnose the problem or provide a solution.

While driving my transmission will shudder and the vehicle will lose power causing the vehicle to slow down abruptly. It also will shift very hard making a loud noise.
