Vehicle less than 150,000 miles and transmission hasn't held up. Vehicle isn't driven hard its my daily driver to work. Transmission temperature exceeding 200 degrees on a short drive, hard shifting into 1,2,3,4 gears. I have done my research looking into other people that have had this trouble and it has become a well known problem with these vehicles. Everyone is experiencing trouble from the torque converters to the gears, and clutches. Its terrible that we are spending 10's of thousands of dollars on a vehicle that will not even hold up to 150,000 miles. These transmissions needs to be recalled and replaced. I have also done further extensive research that shows that from the GM Bulletin you can find documentation that shows that the 6L80 transmissions have problems with this exact issue. This Bulletin was published in June of 2020. If GM has listed 13 different models of 6L80 transmissions in different vehicles that are having such problems. Why hasn't this been recalled to make it right to the customers who have these vehicles. We are being ripped of our hard earned money and left with vehicles that are extremely expensive to have repaired or forced to let them go back or have no option but to trade it in and still be left with lots to pay on these vehicles.

Transmission quit working at 125195 miles. When I called around to Chevy dealers, this is a common problem for this particular year and model. Dealer said it would cost close to $7,000 to replace with a different transmission to resolve the problem. They did not put the same make/model transmission into the truck - they put a different one due to the issues the original transmissions are having. We spent a significant amount of money to get the transmission REPLACED. The transmission needed to replace the bad one was on backorder - due to the demands. I personal feel that Chevy should have recalled the bad transmission and the cost of the repairs should have been covered by the manufacturer. I am a woman and this could have been very dangerous had the transmission quit on the highways in Portland, Oregon while commuting to or from work. Please look into this. I would like Chevy to reimburse us for the repairs we paid. I have an invoice of $4,690. Thankfully it quit a few blocks from my home. I had to have the truck towed to the dealer. That was an additional expense.

Transmission failed because of faulty torque converter at roughly 95,000 miles. Now the same failure has occurred at 115,000 miles. This type of failure is unsafe if it were to happen in heavy traffic or crossing an intersection. GM refuses to acknowledge the issue and demands a certified dealership diagnose the issue. I maintain my right as a consumer to use a private repair shop. They will not investigate any further with my report, without their service department, which is biased and a conflict, providing the diagnosis.

I was driving as I usually do, this time I was in my car I had just financed and bought 3 weeks before. There was no signs or warning lights before this incident. I was driving when suddenly it wouldn-??t go in to gear or any gear at all and realized my transmission was failing. I then drove it and tried to get to safe spot trying to avoid any crashes delays or other accidents. I was glad to be close by to a safe spot and not going at a fast speed on freeway or Main Street when this occurred and avoided an accident. My truck was then towed into the dealership mechanics and was waiting for a report and turns out the truck needs a transmission replacement. During the Transmission tear down and inspect they Found clutch assembly gear 1-2-3-4 and 3-5 reverse plates all damaged. Plates missing teeth and burnt. Excessive metal inside torque converter, and valve body. Clutch drum damaged and burnt. I am now just researching recalls for 2014 Chevrolet Silverado and realized that there is a recall for power train on transmission. Stated -??The subject vehicles may have a transmission oil cooler line that is not securely seated in the fitting.-?? And the Recall consequence is -??If the line is not securely seated and transmission oil leaks from the fitting, the oil could contact a hot surface and cause a vehicle fire.-?? By reading my experience with my trucks transmission failing and having multiple parts inside -??burnt-?? Has me wondering if my truck was part of this recall and how worse it could have been if it would have caught in fire. My dealership failed to mention any problems and stated they -??take every vehicle through a mechanical inspection and smog Saftey.-?? I can-??t believe only 3 weeks of having this truck and no warning signs and to just completely just shut off and have the transmission destroyed/burnt is a horrible experience.

The toque converter is bad and is ruining the transmission. GM is aware of this issue and will be repairing fleet vehicles at no charge. I have a problem with this discrepancy In their policy when they are aware of this problem yet only cover the repair if your a fleet owner.

The 2014 and up Chevrolet Silverado 1500 models are notorious for electrical issues and bugs, some may have been recalled but other were not included in that recall while still having the same issues, these vehicles have major electrical system issues, from bad battery cables, down to every Control Module associated with the truck, over time salt, sand, mud, moisture disrupts certain key areas of the electrical wiring harness underneath the vehicle, General Motors knows about this but fails to recall these vehicles, it creates a very serious matter when you have no traction control, or any ABS function, along with loss of power steering assist. These control systems can be life and death when they are not working!. GM needs to address these issues and recall ALL 2014+ Silverado-??s and alike for these electrical issues relating to -??loss of communication with the ECM, BCM, TCM, EBCM, TCCM, PSCM, etc. these are costly break downs and these modules are very expensive to just throw in and hope it fixes the issue, most dealers don-??t want to trace wiring issues and will just tell the customer cannot replicate which leaves us vulnerable. Some customers state their vehicles will randomly shut off while driving, others report their truck going into -??Limp home mode-??. Nobody can seem to centralize a specific area where the problems are occurring but believe it has something to do with the material and the way the harness was made.

My truck loss of electric power steering it shuts off especially during low speed turning maneuvers. Lost and then returns then might lose temporary control of the steering wheel, increasing the risk of a crash. I have made an appointment at my dealership.

I purchased vehicle new 12/2013 and have had the vehicle to Chevy dealer after purchase due to hard downshifts and banging in transmission on shifting. Dealer claimed condition was a normal condition and would do nothing to remedy. This shifting condition stayed the same until the following event. 10/19/2021 driving northbound on I75 in Michigan at 75mph vehicle starts jerking and banging and starts losing speed. Tachometer is bouncing up and down between 1800-2300 rpm, transmission temp was 270 degrees. Vehicle is having transmission failure. I put transmission in manual mode and used 4th gear at 45 mph to limp into my destination. It was pitch dark, raining and very hard to see and I was concerned of being rear ended if I pulled off the side of the road and waited for a wrecker. The next day I drove the vehicle to a transmission shop, again using M4 to limp in as my brother in law followed behind with his emergency flashers on to alert others of a slow moving vehicle. The independent transmission shop inspected my vehicle and determined the torque converter failed and contaiminated the transmission, lines and cooler with metal shavings. They also commented they see several of these vehicles for the same problem, it's common issue they said. Mileage at failure was 124780. They rebuilt the transmission, replaced the torque converter and flushed the lines and cooler at a cost of $2755. GM should be held responsible to reimburse owners of these vehicles as they knew of these transmission issues and placed the occupants of vehicle at risk of injury or death if this issue caused a collision. I have attached documented complaint at GM when vehicle was new of clunking and banging in transmission and their answer was its a normal condition.

Vehicle starts to shake when driven above 70mph. If brakes are applied to reduce speeds from 75-70 the shaking significantly increases, but decreases to the normal shaking once the brakes are released.

1) transmission when out while driving at 55 ml per hour, truck only had 107,000 miles had to replace transmission more like a rebuild transmission from the dealer. 2) my air conditioner when out 9 months later after replacing transmission, there was a leak on the A/C condenser, dealer replace the condenser two years later air conditioner when out a gain with the same problem A/C condenser leaking the condenser that dealer replace. This's not coment and I think GM needs step in to the plate and looked in to this transmission issues and air conditioner condenser leaking refrigeran.

My transmission failed and I couldn't go over 40mph. The truck would jump and bounce and make loud screeching noises. At first I thought it was all the transmission. I asked a family friend who is a mechanic and he diagnosed it. He concluded that the transmission wasn't the only problem. The motor was having difficulties changing from V8-V4 also. I have been told by many people that I need to get a tuner to delete the computer program that changes the amount of cylinders firing. I have also seen/heard trucks that go without the delete too long. Also, my power steering will fail at low speeds while turning. GM fails to see that my truck has this issue. Saying it doesn't affect my VIN.
