2015 Chevrolet Silverado 1500: harsh or hard shifting

Filed May 19, 2026 · Transmission · KS

When slowing down, just before coming to a complete stop, the transmission will downshift, clunk and the vehicle will jump forward, powering through the brake pressure that's already applied, to the point I have almost collided with the vehicle in front of me. This incident has occurred numerous times over the years since vehicle was purchased new.

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.

I was driving on a busy street with a speed limit of around 45 mph and my torque converter failed causing my transmission to fail and my truck to become disabled in the middle of a busy road. It blocked traffic causing a potential danger to surrounding motorists and required assistance to be moved to a nearby parkin lot and later to be towed to the Chevrolet Dealership. The dealership confirmed that the transmission had failed. I subsequently took it to a specialist transmission shop that dismantled it an indicated that the torque converter had failed (a known problem with this year and model transmission) and that the failure had led to catastrophic damage to the transmission. There were no warning signs other than a couple of hard shifts just prior to failure. I was lucky that this occurred on a dry level street and not on a narrow mountain pass while pulling a trailer where the results could have been much different.

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.

Transmission sounds different and clunks lightly once in a while. There is a known problem w this type of transmission but GM is not accepting it as a recall concern and many dealers are ignoring repairs are needed.

I am getting a lot of clunking in a transmission when it's up shifting and down shifting. On the road under 55 MPH. Idle surges when it's switching gears. When it goes into v4 mode at any speed it starts to shudder and vibrate to the point and you can feel it in the gas pedal and steering wheel and a little bit in the seat. And now its making a rubbing noise.

Our 2015 silverado 1500 has stuttering/ hesitation when accelerating, when turning on to a street you can not get up to speed quick enough it acts like there is something hold it back. We have replaced the spark plug and wire and all the coil packs. The voltage meter on the truck keep fluctuating so we replaced the alternator and the battery and that did nothing and kept fluctuating so we got another alternator and another and another and another.. So 5 alternators later and still no fix. But the hard shifting is the main concern. Because when you are driving trying to get into another lane the truck with just start hesitating and jerking until it launches into gear. 1st gear going into 2nd gear the truck will shift extremely hard and 2nd going into 3rd feels like you are galloping until it finally engages. The computer has been replaced and reprogrammed with all updates by and ase certified mechanic. Also did a transmission fluid flush and changed. No service light. Just baffled with all these complaints about transmission why nothing is down. It is a serious safety issue.

When my truck was under factory warranty it had a ratcheting clunking noise coming from the rack and pinion. The truck had 89000 on it and I called chevrolet filed a complaint. I was driving last summer and I lost my steering going down the road then I got it back. Then I took it in for the software update recall. The chevrolet garage told me that the rack and pinion is not covered under factory warranty. Now the truck has 109000 and the rack is binding worse. I did my research and found out their is alot of people with the same problem I'm having. These racks need to be recalled before someone gets hurt.
