My vehicle has been properly maintained since new. At around 90,000 miles the transmission started making noise. I had trans filter changed and the noise abated. at 92,000 the car started shifting oddly. Several times on the highway the engine would rev and the car loses speed. Loud noises from the transmission and hard shifts. I most recently was unable to accelerate while getting on the highway. This is a truck, I have things I have to transport. I am unsure if I should continue to drive on the highway. I am going to my local dealer next week to explore repair options. I have learned that this problem is well-known to GM.

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...

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.

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.

- West Memphis, AR, USA

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.
