2015 Chevrolet Silverado 1500: stuck in gear or won't shift

Filed May 19, 2026 · Transmission · KS

I purchased this vehicle brand new. From day one I have had constant transmission related issues that make it feel unsafe and unreliable. When it was still under the factory warranty it was brought back to dealer multiple times. Each time I was told it's a normal characteristic of that transmission or that a simple fluid flush would fix it. It was flushed a couple of times and it would "help" for a short while. Software for the transmission control module was updated by dealer. Nothing that was done ever actually fixed the issues. The transmission bucks, jerks, clunks when up & down shifting. Lunges forward when almost to a complete stop. Shudders at higher speeds above 45-50 mph. Occasionally if I slow down from cruising speed and press accelerator to speed back up, it doesn't accelerate because it won't shift down from the higher gear it was in.

After start up and when putting the vehicle into drive the transmission seemed to not recognize and then began clunking into gear. While driving it felt like it was slipping and racing with no response. The vehicle became to precarious to drive on the road because the gears wouldn't shift and the vehicle decelerated quickly and would not accelerate upon demand. I felt as if I could endanger others and lose control and endanger myself and the occupants of the vehicle. We chose not to drive it and bring it in for an assessment and ultimately was told of the problem and agreed to the repair to gain our vehicle back in safe working condition. The vehicle needed a total transmission rebuild and torque converter as well as other tranny related items. No warning lights but we did begin to hear a whining noise while cycling through what seemed to be the gears.

My truck shakes frequently going down the road at certain speeds. I've had it for around 6 years now and I can't pinpoint exactly when it started. I've had the truck in for maintenance/service at the dealership as well as other auto shops trying to diagnose the problem. I've had new tries, new brakes, countless tire rotations, wheel balancing etc you name it. And the problem persists. Recently after hearing about the "Chevy Shake" I've come to realize that my problems are just like what others have too. Now my powertrain has given out. And my extended warranty has ended. I truly believe that the issues have caused, or are caused by this prevailing issue of a wobbling drive shaft. Every time I have had it in for repairs the issue still persists and I can't always get the time to go back and have it looked at it again. It is a safety issue above all else and I truly believe GM knows about it but does nothing. Even more to the point, I had a "transmission fluid flush" just under a month ago and now all of a sudden my truck doesn't shift like it should. They say it will cost over 5 thousand dollars to get repaired. There is something seriously wrong here. This is an ongoing issue, and again it is difficult to say when it started. But a vehicle going down the highway at speed limit and shaking is a safety concern.

Transmission failed at 93k miles. Luckily for me, I was a month away from warranty expiring. However, so many people have ended up on the wrong side of the warranty I wanted to make sure I file a report so gm can maybe recall their weak transmissions or torque converter. Trans has been shifting and shuddering so hard from 1st to 2nd gear and 2nd back to 1st. Was driving home from work on the highway and all of a sudden trans would not shift into 6th gear. When taking exit home, truck died. Restarted and got codes p0741 and p0700. Took to dealer and they replaced the transmission. Fluid smelt burnt and metal shavings in pan.

Me and over 100 people I know have had issues with the 6 speed transmissions in the 2014+ silverados. Mine currently is shifting hard. All of these vehicles are experiencing way too many issues before they should (less than 150k miles). Sometimes my transmission won't shift and leaves me going at an unsafe slow rate of speed in the middle of a busy highway

Our 2015 chevrolet silverado 1500 z71 had transmission issues at 38,000 miles and the vehicle had only 84 miles when it was purchased. The transmission would not shift out of first gear and the check engine light was on. I could only drive about 70 MPH on the interstate and it felt like I was pushing the engine. This was while returning the truck to the dealership where we purchased it. We are disappointed with the performance of a vehicle we paid good money on. The vehicle is currently at the dealership and is line with 15 other vehicles with transmission problems. This is not what I thought chevrolet gm was about with the production of their vehicles.

Transmission doesn't shift right between 2 and 3 and on down shifting. Never drove a vehicle that does this. Was told nothing is wrong with the trans.

Transmission problems. When reversing up a driveway the truck will stall as the gas is pressed it will rev up but not go anywhere, then jump into reverse as if the petal was floored. Also some times when entering the highway the transmission doesn't shift into the correct gears also jumping into gear which could cause accidents.

This truck has the 6.2 and 8 spd trans. I start it up in the garage and let it idle down, back out of the garage into the street, put the car in drive and feel it engage, push on the gas and it doesn't move for a few seconds or now it will move but then when it tries to do the 1-2 shift it won't shift and the truck stops moving forward for a few seconds until it finally does shift. I had it in to the dealer at 13k miles and they determined there was a problem with the stator support in the trans allowing the converter to drain so they did a partial trans rebuild and updated the parts. The original problem is showing up again along with the 1-2 shift problem. I took it in again at about 18k miles and the dealer said that they could reproduce it and the issues is caused by the "clutch" not being filled with fluid at the time the shift is trying to happen. Once the clutch is full...it shifts. I was also told by the dealer that this is a documented issue with gm and there is a bulletin out on it telling dealers this is normal and to not do any repairs trying to fix so they did a software update and put the trans back into learn mode said they were sorry and gave it back to me. This condition is an accident waiting to happen when you expect the vehicle to move and it does not. This transmission is installed in chevy, gmc, and cadillac trucks and suvs and there many complaints on all of the popular message boards online about this exact same issue. Some people have complained about almost being hit in the rear because there vehicle won't move. There are many other documented issues with the 8 spd trans gm has been using in their trucks as well and gm will not address any of them saying that they are all normal. I have talked to plenty of other people personally that are experiencing the same issues as well and not getting anywhere.
