2015 Chevrolet Silverado 1500: transmission slipping

Filed Sep 29, 2026 · Brakes, Transmission · TN

At 124,000, the transmission started slipping and not grabbing gears. Coleman Taylor Transmissions ended up having to do a full rebuild which costs about $4000. At around 20,000 miles, the vehicle started to shutter going 45 mph. The vehicle still does shake violently at 62-75 mph causing a safety concern. The brakes wont go if Ive been standing still for a long time like in a drive through or backing down a boat ramp. You have to stand on the brakes with both feet to get the vehicle to stop and thats only going 5 mph. We still own this vehicle and still have issues with it.

While driving at highway cruising speeds, the vehicle began showing abnormal RPM fluctuation/surging at steady speed. The RPM would repeatedly move up and down even while maintaining a constant speed, including when cruise control was used. There were no warning lights or dashboard messages at the time the symptoms first appeared. The suspected failure is the torque converter/torque converter clutch in the automatic transmission. After diagnosis, I was advised that the torque converter failure contaminated the transmission fluid/internal transmission components, and that the transmission now requires replacement. The failed transmission/related components may be available for inspection upon request, depending on repair timing. This condition created a safety concern because the drivetrain was not operating normally at highway speeds, causing inconsistent power delivery and concern that the transmission could slip, overheat, fail further, or leave the vehicle unable to maintain speed in traffic. A sudden loss of propulsion or worsening transmission failure could increase the risk of a crash. The problem has been diagnosed by a transmission repair facility. The vehicle has not been inspected by the manufacturer, police, or insurance representatives. No crash occurred. No injuries occurred. No warning lamps appeared before the failure. The first noticeable symptom was the RPM flutter/surging at steady highway cruising speed. The exact internal cause is unknown, but the best assessment is torque converter/torque converter clutch failure resulting in contamination and failure of the transmission.

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.

The transmission began slipping and failed at 106,000 miles in spite of obtaining all recommended services throughout the life of the vehicle. It failed completely while driving, which was a major safety issue. It now needs a new transmission. After searching online, I see that numerous owners have reported issues with the 2015 Chevy Silverado transmission. There were no warning lights. It began to make a noise and a shaking and failed about one week later.

It started out with the transmission slipping/jerking at about 50 mph. Then as it progressed it began whining. We were barely able to get it to a mechanic to have it looked at. We were told it was the torque converter which caused the transmission to need to be replaced.

Transmission slipping, set cruise control and it would engage for some time and then disengage without warning. I followed all maintenance requirements for the transmission like flushing the transmission at the appropriate mileage.

Break system failing. It happens time to time when at slow speeds. Mostly when trying to slow vehicle ot a stop at a low speed. Requires bodyweight pressure to stop the vehicle. It still feels like its slipping to a stop. This is happens when in reverse and forward.

Transmission would not change gears. Slipping and caused high revs and sometimes would shift. They told me the hub that contained gears 4-6 was damaged. This a few months after cylinder #7 blew and had to replaced. All of course a few months after the warranty expired. Been complaining about the transmission for years.

The truck and transmission shift very hard, slip or can't find its home. The problem is the worst between park and reverse, and 1st and 2nd gear around 20mph. I have taken it in multiple times times and told everything is operating to spec. One time I was told they were waiting for guidance from gm, but then forgot about that, and said everything is fine.
