Transmission keeps going in neutral all by itself. Me an my family has almost got hit several times

- Citronelle, AL, USA

My wife came home and told me there was something wrong with our truck. I went and inspected it and found nothing. The next day i drove the truck about 30 miles up river. Coming home I was traveling around 55 mph the truck came to a sudden slow down as if I had locked up the brakes then drove fine again. This happened three or four times not as bad as first time. While in town stopped at a light it tried to take of. Not like something giving it gas but like it was in gear and the brake wasnt going to hold it. Almost put me into a school bus ahead of me. Then the rest of the way home it kept binding down and releasing then binding back down. Hard to control but not necessarily a break problem. Its something else. I have worked on vehicles all my life, professionally for 25 years. I never seen a vehicle do this. It has to be in the transmission. Maybe something in the torque converter would be my guess. I have heard of the issues with the 8 speed ever sense this happened I have parked this truck. I cant afford a need transmission that doesnt actually fix the problem from what i hear. I feel GM needs to do something here. At least pay for the parts to fix

For several years this truck will at times start "grade braking" on its own. In other words, at speed, ie: 55 mph, the computer chip will tell the transmission to downshift to assist in "grade braking". The danger is that it actually speeds up the truck, and while attempting to stop at a stop sign, (or light), the truck is actually speeding up, while I am actively pushing on the brake pedal to stop at the light. I ended up having to replace the transmission with a new (rebuilt) transmission. I hoped this would end the problem, but now once again, I have the problem occurring with the replacement transmission. GM tells me they cannot program out the grade braking component. This is a very dangerous situation in which one day I will be unable to stop where required, due to stopped traffic, or a stop signal.

vehicle is shifting hard between 1st and 2nd. it only seems to do it at lower speeds. the RPMS had a shudder between and only once the truck has been running for awhile. has been in to an independent service dept. at the local dealer where it was purchased and has had all work done since purchased. there are no warring lights or check engine messages. they flushed all fluids and hooked to diagnostic machine found nothing. had it back for a week and it did it again. Took it back to them and had them ride along so they could see what it was doing. they replaced the torque converter although the shudder is gone but it still shifts hard between 1/2

NHTSA campaign number 18V586. GM-??s recall is 18289. Power steering at low speeds with voltage drop causes power steering to lose control

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.

I am having issues with my transmission. When I first turn on the truck in the morning, put it in gear, and lightly accelerate the truck accelerates way too fast then cuts out the power. It is enough to throw me forward or back in my seat and it honestly is frightening. I am also having problems with the vehicle shifting incorrectly causing me to have no power or a sudden surge of power. This is usually when i have slowed down and them am trying to accelerate again. Also, When I am slowing down to stoplights, the vehicle will occasionally shift down to too low of a gear and act like i am slamming on the brakes. I have had several close calls with this truck due to this issue. Gm knows about the issue and has refused to recall the vehicles that are having these problems. They are recommending changing out the fluid multiple times at the owners costs. This has resulted in several class action lawsuits. They also have gone to the lengths of changing warranty coverage to no longer include abnormal shifting. This is not safe. This is causing accidents and they are actively covering it up. Please help the hundreds of thousands of people that are having issues. We need your help, I need your help and gm is no longer standing behind their vehicles.

6l80 transmission has the Chevy shutter or slipping truck only has 60,000 miles not very optimistic that it will last till the 150,000 miles if it-??s already acting up and I can hear metal slapping when shifting at various speeds and stopping speeds

The Chevy Silverado shakes around 65-70 mph and is continuing to worsen over the course of time. The original driveshaft may have been replaced by a dealer in the past (vin shows zero recalls to a known failure caused by aluminum driveshafts), but they have been replaced with the exact same aluminum driveshafts. This never resolved the original failure, but only pushed the failure down the road temporarily, putting new buyers safety at risk.

I was driving on the Freeway, when the gears on the Transmission started to idle. I was going about 65 miles per hr, when the vehicle would not move, even as a stepped on the gas pedal. I was able to put my hazard lights on and pulled over on the side shoulder of the Freeway. I immediately put the vehicle in park mode. While in park mode the vehicle started to make a very loud screeching noise. I turned off the vehicle to see if this would troubleshoot the issue. I turned vehicle back on and the noise did not go away, I put the vehicle back into gear and it would not move, it started to shake and the vehicle jumped into which I believe would have been 3rd gear. I was able to drive the vehicle to my house at 5 miles per hr with the Hazard lights on. My house was only 2 miles from the Freeway Exit. During the 2 Mike drive to my house, the vehicle kept jumping into gears. This could have caused a major accident on the Freeway. I need answers.
