2015 Chevrolet Silverado 1500 Power Train

After years of driving like a grandma, my transmission unexpectedly failed while travelling down the freeway at 70mph. There were no warning signs, no vibrations, and I changed my transmission fluid at the dealer-recommended intervals. Huge bummer, really. I use my truck for work, and because of the time of year, it is unlikely that I'll be able to get it repaired for a few weeks. Certainly not going to help my bank account either, since a new transmission from Chevrolet is $4,800 before labor and other parts.

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.

For years I have taken my truck in to see why it is grinding when shifting and was told it was nothing. Now it got so bad my truck completely lost the ability to accelerate at all. The records I had at James Corlew have been lost since they changed to a new owner. I have spent over 7000 to get this fixed

Transmission failing when going up hill almost causing a wreck and leaving me stranded. Was inspected by dealership and they rebuilt the transmission problem keeps occurring. No warning lamps. Have spoken with other Chevy Silverado of same year and style and many have had the same issue.

Transmission failure at 133,000 miles due to faulty tourque converter … which was replaced AFTER … i repeat AFTER… replacing all components that failed because of the faulty torque converter … so now its showing same symptoms as did before failed … only 30,000 since repairs

Transmission just won’t last in this truck and it’s dangerous when you have kids in it

The contact owns a 2015 Chevrolet Silverado 1500. The contact stated that after driving on the highway and driving uphill, the rear differential started grabbing. There were no warning lights illuminated. The vehicle was taken to the local dealer, who was unable to determine the cause of the failure. The vehicle was taken to another local dealer, Oliverio Buick (1110 Laurel Hill Rd., McDonald, PA 15057); who determined that the rear differential fluid needed to be drained and refilled. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was approximately 82,000. The VIN was not available.

The valve body on my transmission failed and needs to be repaired again. It was already replaced by gm, 1k miles later it failed again.

The torque converter with the 6L80 transmission went and destroyed the transmission in my 2015 Silverado. Which is going to cost me thousands of dollars to fix. With the 10's of thousands of people affected, Chevy should of done a recall on the torque converter and/or transmission. There were no signs/symptoms, the truck started shaking like I was driving over rumble strips, no check engine light. I was able to get it to a mechanic immediately and it sits there unusable at this time.

Transmission shudder and hits hard at times.

The contact was able to coast to the shoulder of the roadway, where the failure persisted. No warning lights were illuminated. The vehicle was taken to an independent mechanic, who determined that the transmission required a flush and fluid replacement. The vehicle was repaired, but the failure reoccurred. The manufacturer was not notified of the failure. The failure mileage was 132,000.

In the middle of driving the truck stopped working and wouldn't accelerate. No light for the engine was on and no warning. Truck won't restart

I bought my 2015 Silverado Z71 LT new in 2015, after a few months I started experiencing the "chevy shake", I took it back and they replaced the tires saying its fixed. It didnt fix it, after getting ready to call and go back it stopped doing it. Throughout the years it has done it off and on, I have had the driveshaft balanced, 3 sets of wheels and 5 sets of tires, U-joints, both fron CV Axles, bearings and bushings in the differential, transmission checked and fluids and filter changed, still does it. The truck only has 38,850 miles, I saw that there is a class action lawsuit against GM for knowingly selling these vehicles with bad driveshafts or transmissions. I will have it back in the shop Tuesday 9/24/24 to have them look again.

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 transmission is not shifting into gear and is not pulling anymore. Also,the transmission has been shifting hard and jerking into and out of gear while driving. The jerking into gear while driving has been going on since I purchased the truck in 2015. I told the Chevrolet dealership about it a few times. I even asked if there was a recall. Their answer was, no recall and all of the Silverado transmission pull like that.

See attached document for complaint.

Torque Converter failure. The torque converter went out suddenly with no warning of possible problems. No engine, or transmission warning lights. Just suddenly started jerking when accelerating. RPMs jump every time it jerks.

The transmission has failed in less than 150,000 miles. I was driving in traffic and lost gears. I stopped and tried to get back going and I was stuck being a traffic hazard to the other motorist. I talked to a local transmission shop and he stated that the 2014-2016 Silverados are known for transmission problems even when they were new. He’s rebuilt hundreds of them and Chevrolet should have recalled and fixed them. There were no warning lights or anything through the truck.

The manufacturer was notified of the failure and the contact was informed that the VIN was not included in a recall. The failure mileage was approximately 190,000.

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.

transmission failed at 70 500 miles

Transfer case is shifting to neutral while driving

The truck shutters and shifts horribly hard. Check transmission light is now on.
