I've noticed since the first month of owner ship back in 2018, that something was wrong with my transmission. I own a 2017 Chevy Silverado with the 8 speed transmission. Not only had it been discouraging, it's disturbing, and possibly even unsafe. From 1st to 2nd gear there is a hard shift in the transmission. And the same problem is from 2nd to 1st gear. The vehicle makes a loud clunk and it jerks simultaneously. The fact I spent $50,000 on this truck brand new and have got nowhere with the problem is outrageous. I always believe it is a safety concern, because the vehicle will move it radically. When I brought it to my dealership they said it was 'left in 4 wheel drive' ridiculous lies. And if that was the case why did they 'update the transmission computer.' Regardless, all of these problems from GM have been swept under the rug. The problem has never stopped. I've gotten replies from service representatives at the dealership saying 'they all do that' or 'it's fine' so tired of getting nowhere. GM should be replacing every single 8 speed transmission. I am worried that my transmission will fail at any time. New vehicles should not drive like this.

When coming to stop my truck regularly has very hard downshifting. Along with a very audible 'clunk' from the rear end, I will experience a feeling that I can only deceive as being hit by another vehicle. This results in sometimes having to brake harder as you feel like your going to move forward rapidly. A very similar experience happen when pulling out slowly in low gears. These two combined can be extremely hazardous as well as just very obnoxious/annoying when driving in a yielding situation.

Transmission shudder at speed. Hard shifts at slow speed. Appears to be well documented across this site and other forums. It appears the oil used in the transmissions was defective (per Chevy). Tsb - 16-na-175 and tsb 18-na-355. Hopefully adding to the long list of complaints helps get Chevy to issue a "recall" or something similar to resolve the issue with the flush procedures or similar fixes.

Hard downshifting when going down hills at slow speed. Jerking and clunking noise, and RPM goes up and sounds like gears are grinding. I have taken it to the dealership and they tell me nothing is wrong. It happens every time I am going down a hill with the breaks applied and going at a slow speed. The truck jerked so bad that the seat belt locked.

A 2017 Chevy Silverado with a 5.3L at 80000 miles the water pump went bad I had a 2006 same truck and it was 200000+.miles before I had to deal with this issue. I don't know if I'm the only one that had the water pump issue so soon or if this is a common problem with this truck that needs to be looked into, also excessive noises from the transmition when up or down shifting at low speeds and is like if struggled to down shift when you need it like when you need to pass a car in front of you most times you have to give it excessive throtle and only then it downshifts in a violent manner, again do not know if this is something that is only happening to me or if there is someone else out there with the same truck having similar issues, thanks.

Passenger air bag off light inoperable. Check 4 wheel drive warning comes on intermittently. Dealer charged $138 but could not find any problems. This occurs when driving.

- Williamsburg, MI, USA

Truck down and upshifts hard. When slowing down for a car in front of me, when I get back on the gas, the truck has no power like it can't figure out what gear to be in. Makes a loud clunking noise with light acceleration from 1st to 2nd gear. There is major hesitation when trying to down shift no matter what gear I'm in. Problem needs to be fixed before someone gets injured. Been to Chevy 3 times for the same problem and all they tell me is the transmission will learn how you drive. They also told me there is no new update for the transmission module so I'm screwed.

The 8-speed automatic transmission exhibits numerous issues. 1) when slowing down to under 10 mph, as if you were yielding to traffic and then pressing the throttle to accelerate the vehicle, two issues can occur. First, the vehicle's transmission can hesitate between gears, providing no power to the wheels. Second, when vehicle does shift into a gear, the vehicle can lurch forward unexpectedly as if you were hit from behind. There is sometimes an audible "clank" when this issue occurs. This issue can prevent a driver from successfully entering traffic due to loss of instant power to the wheels. 2) during low-speed acceleration, the vehicle can hesitate between the first three gears, providing no power to the wheels. It has a similar feel to a transmission that was slipping. This can cause a driver to over-correct the deficiency in power to the wheels by applying excessive throttle and cause an accident. 3) when proceeding slowly in stop and go traffic, the vehicle can shift up or down suddenly, causing the vehicle to lurch forward unexpectedly. There is sometimes an audible "clank" when this issue occurs. This can cause the vehicle to strike the rear of another vehicle, in tight traffic, if the driver isn't prepared to apply the brake when the event occurs. 4) when driving normally, the transmission may hesitate to downshift when the accelerator is applied as would be necessary when trying to pass a vehicle. This does not appear to be gear dependent. The loss of instant power can prevent the driver from successfully overtaking another vehicle in the event they need to conduct a passing maneuver.

2017 1500 Silverado, jerks, surges, during acceleration. Now and then I get a loud thud in the rear like I got rear-ended. When coming to a stop from 2nd to 1st.

Driving from Connecticut to South Carolina my truck developed a bad vibration between 45mph to 70mph. The dealer says that the transmission needs to be flushed. This vehicle has 34K for miles. They claim that no damage is being done to the transmission. This I believe is a safety issue and should be recalled. The vehicle is still at the dealership and my family and I are stranded while they claim that GM needs reading before they can flush the transmission fluid.

Transmission has stopped working properly.

- Southlake, TX, USA

When at highway speeds (anywhere between 40-75) there is a very noticeable shaking when engine is under light load (just keeping speed). I have taken in to Chevy dealership and they changed the transmission fluid and that worked for a couple thousand miles. Not the "Chevy shake" is back at full force. Upon calling Chevy, they claim to know that their trucks do this, but say there is not a fix to solve the issue. They claim they have no clue where it's coming from, but should not be a safety hazard. My question is, if you do not know what it is, how can they say it's not a safety hazard. I am so afraid that my truck is going to break down and it's not even two years old. I have read the thousands of complaints online with people having the exact same issue, since the 2014 model. They have had enough time to figure this out and should be held accountable.

The transmission shifts hard in low gears (upshifting and downshifting), lunging forward and a hard knock in the transmission. Chevrolet cannot fix it!

- Charlotte, NC, USA

8 speed transmission harsh jerks between 1st and 2 gears and 2nd and 1st gears typically occurring on slight downhill grade harsh jerk and knock/hammer noise common to occur after vehicle has been sitting and in stop and go traffic such as school drop off with children around and rush hour traffic

Transmission started slipping at 72000 miles, replacement or rebuild.

- North Little Rock, AR, USA

Shortly after purchasing my truck, I began experiencing hard shifts, gear searching, clunking and hanging between gears. Occasionally the shift would be so hard it would feel as though the truck was struck from behind by another vehicle or object. Multiple trips to the dealer has resulted in numerous attempted fixes with no relief of the problem. Currently the truck is back at the dealership having the entire transmission replaced. This is causing a depreciation of the value of the truck as well as an unsafe condition while driving.

Truck transmission was good until about 2,000 miles. Truck has delays when putting in gear after it sits overnight. Truck has harsh low speed downshifts. Problems are real bad when vehicle is cold. When you come to a complete stop and let off the brake the truck will sometimes lunge forward. Took truck back to the dealer where I bought it and they said nothing was wrong so I made an appointment for a week later with another dealership. They did a "timing" test and felt the delay and did 16na364 update. It seemed to help for a couple of days and problem returned. Both dealerships are aware of the problem but GM is not providing a fix. I now warm the truck up a few minutes before driving to help with delayed gear engagement. Harsh downshifts continue with the lunging and slow response at times when applying gas petal. You have to be very careful when driving this truck because of the transmission problems. There are many complaints for this not to be a major problem. This vehicle sticker price was $64,000 dollars. I wish I had my old truck back because it was reliable and not potentially dangerous to drive. General Motors need fix this problem or at least give an free extended warranty. The dealers will fix the transmission if GM will tell them how.

Very hard shift going from 1st to 2nd gear and from 2nd gear to 1st gear. The shift was so hard that the tires made a chirping noise and hardly any throttle was being used.

- River Falls, WI, USA

Experiencing hesitation/'chuggle'/convertor slip in 2nd-6th gear in V8 mode when rolling into the throttle and putting the engine under load on a highway. Especially noticeable when in 4th 5th or 6th gear,1500-1850 RPM, loading the engine to accelerate 55-60mph, 60-70mph. Or when accelerating on an incline at same speeds without downshifting. Or when slowly applying throttle to maintain speed (65+) against a head wind or when trying to pass a car. All while maintaining current gear and no downshifting.

- Overland Park, KS, USA

At low speeds under braking when downshifting from gear 2 to 1, the shift is not smooth. There is a significantly loud clunk that you can feel and hear, and passenger safety is compromised due to a sudden lurch forward.
