Update: still waiting on an appointment with Chevy - transmission has had no shuddering events since. Will update again soon! Ps - was tired and rambling on the go, editor did their best to clean it up, still new to this 👍
Drive your C8 in manual mode. The problem is the AFM active fuel mgmt software. It will not show as a fault. AFM will wreak havoc on your Trans. Driving it in manual mode will disable the AFM software and will resolve the issue. GM head engineer for C8 design covered this issue a while back.
sorry Dude, I heard a lot of transmission issues with the C8. I will wait until GM sorts out all the issues with the C8 before I commit to purchasing one.
Had DCT issue this past summer and it was the valve body. They replaced and did a tune and it’s been golden. My friend here has a ‘20 as well and he lost odd gears and had the DCT replaced. My car had very hard shifts and a warning I the DIC that read ‘Rear Axle INOP’. You really have to be looking for the warning as you get no ding or bell when it pops up and it only stays on for so long. I had about 5500 miles on the car.
I didn't see anything. Diagnostic came back normal. Just waiting for a second approval and a more in depth inspection. Good news about the valve body though, glad to hear it's not necessary the end.
I’ve had stuttering/shuddering issues for almost two years since it was new. It’s been in the shop 5-6 times. A different story every time and of course no problems when service took it for drives. Dealer said I needed fresh transmission fluid which of course wasn’t under warranty!
Hope your transmission trouble gets resolved ok. But I want to complement you on being one of the very few drivers I have watched that uses their turn signals all the time.
I was very excited about the C8. I was going to sell my c5 or c7 Z06 but the slushbox is just a deal breaker. Yes the advantages over the c7 are there but after running my friends c8 at a few autocross events I will stick with the two I have.
I just bought a 22 C8 and my first day of ownership got a CEL stating high fluid pressure in the transmission. Dealer said it was a valve body and GM is going to replace it. Now I'm worried what the lead time is on that trans...
Same thing happened with C7's with 8-speed automatics. Years later GM discovered the transmission fluid needed flushed and replaced with different fluid.
@@silverfoxc8 I thought GM discovered the transmission fluid absorbed moisture. Claimed ot needed triple flushed with the newer fluid. Others suspect the Active Fuel Management contributes to these transmission issues. Not acceptable, but sadly I do not think they care.
Had my 2020 C8 transmission replaced twice. Less than 20,000 Mile's on it. Just picked up a 2024 Z06 on Tuesday and with 169 miles on it, I got a transmission hot, pull over message. Long story short, I need a new transmission. What is going on GM??
Having this problem between 1.5-2k rpm’s on the highway. Doesn’t matter if it’s 5th 6th or 7th gear. Generally between 65-80mph, also noticeably worse when on an incline. Car chatters/stutters rapidly and you feel the jolt from front to back until it gets over that 2k mark. Have had this problem pretty much since I purchased the car last December, but gotten worse now that I’m at 17k. Scheduled to bring it in soon
So long story short, they said I need a new valve body. The car has been in the shop for 7 weeks now! The part is still "en-route" to my dealership with absolutely no idea when they will receive it due to the ongoing strike!! Currently have an open case with GM regarding compensation for this mess.@@silverfoxc8
My C8 transmission just went out at 196miles I bought the car 2 weeks ago. My first time going through this with a car I don’t know what to expect , would it be considered a lemon?
One thing to know: engineers design the internals of any car but the people working in the factories assembling the car sometimes are not the smartest or even the most caring. They're just there to get a paycheck, clock-out, and go home.
I like Chevy products too but I have to hold them accountable all togther..there's no way a car of this caliber should be suffering from transmission problems so early..class action suite for sure 😢
Very odd how it is somewhat intermittent. Not happening today in your video. Good luck, looking forward to hearing the updates/solution. Happy New Year!
Hope the problem gets resolved. I know this can be annoying. However, why are you driving at 75-80 mph in 6th gear vs 7th or 8th? The engine is turning faster than it needs to be. Not saying it relates to your problem, but it can impact engine longevity.
@Joe Davis Where shall I start? The Chevy Silverado, Tahoe, and Suburbans with the AFM equipped 5.3L and 6.2L V8 engines where the lifters would collapse and score the camshaft, wiping out the engines. That and the problems with oil and transmission cooler lines would fail and leak, ABS pumps would fail, electrical gremlins. The Traverse line of crossover SUV's with the timing chain shredding 3.6L V6 with oil consumption issues, transmission problems, and electric problems. Those are some examples. The cars suffer from lack of quality control, poor engineering, and overall constant failures. Those are some of the main reasons from being an insider.
Took my 2024 c8 in for a oil change two days ago first one @ 1,000 miles , they told me my transmission is leaking and want me to bring it in tomorrow 😮 hoping it’s not to serious
Automatic transmission are convenient but too complex for my tastes. Been driving cars with MTs for 36 years and have not had rebuilt one or replaced one yet!
I have a 2022 C8 with 4,450 miles I am having shifting issues it won’t shift or revs high between gears I’m taking it to dealer as soon as I can get a appointment
Sorry to hear that. Definitely get it looked at. Mines been fine since the incident. Definitely looming forward to seeing what a deeper look at GM finds.
@@silverfoxc8 I had a ford focus with the DCT transmission in it. For 3 years straight the transmission went out. It was under warranty. I give up on it and sold it. Now I have a manual transmission.
Since new, my 2020 sometimes will not automatically shift up/down. You can manually shift just fine and it will auto shift to first at a stop. Usually goes away in 5 or so minutes. Seems more like an electronics issue since it shifts fine manually. Dealer says they would have to duplicate problem and if they don't find anything, a future out of waranty problem would not be covered. Anyone experienced this?
Please keep us informed on the progress, I'm on the C8 allocation list. And if this is a continuous problem, I'll have no problem of canceling my name off that allocation list.
Trust me, you do not want to cancel your allocation. Chances are you will get the car and it will be perfect in every way. if you’ve never owned a C8 you’re going to be in for a treat! Again Do Not cancel.
Do you garage your C8? How many times have you gone for the zero to 60 in 2.8 seconds. More then once you were wrong. Operator error is more likely then the the transmission. I my first C8 22500 miles and the had no transmission problems. Most of the time I pulled both paddle shifters as I approached a full stop and then hold one paddle to stay in neutral until the light changed. Then I release the one paddle, the 8 speed started in First gear. As I rolled away from the stop I would tap the resume button an smoothly pul away from the crowd. As I would glance in the mirror the crowd was about a block behind with out any drama. I was moving at the preselect traffic speed. Now all the C8 abuser need a transmission r two so I can’t get an allocation for my new HTC C8 Sting Ray I am in line to get for over 6 month now. It will be Torch Red with a tan interior and at this rate may be a 2024. If they don’t give an allocation to my Classic Chevrolet in Flyover country I may have to pay extra for the 2022 Gray C8R on the dealer floor to have a new HTC in my life time. Thanks all you 8 speed DCT abusers for my time in line to get in Line!
Definitely don't abuse the car. Have already swapped out the fluid and filter multiple times. Sorry you can't get your car, hope you get the one you want soon.
Good ol GM. manufacture defects out the bum. Welcome to the 30k miles club. Put 30k miles on my chevy and it started having serious problems. coincidence? i think not. oh and my car has a warranty on it they refuse to honor so my car has been down since april 2022. will be a damn year soon. GM fails us again.
They know the problem exists. They should be replacing the trans. Instead they are waiting for your warranty to run out so they’re off the hook. If mine does that I will drive it through their fkng museum.
Idiots at GM need a manual transmission option ... problem solved Woman's transmission in New corvette is killing true driving experience Paddle shifted... ill keep my old school corvettes no transmission issues All manual
Question is has anyone NOT had issues with the c8 transmission. I’m selling mine. I feel it’s a matter of when. I think every one will fail within 40-50 thousand miles. I’m dumping this pos. Gonna look into a nice Acura or maybe a challenger.
Even if your trans wasn’t having problems you shouldn’t be racing a Lambo. You don’t have a lambo you have I nicer fiero. And it isn’t funny when you pronounce it wrong. Also the trans problems were mainly in the 20-22s seems to be a lot better now. Sucks it happened to you
the transmission is as jerky as these awful cuts in the video. Jeebus cripes man, can you just talk and not make a dozen skip cuts in a row? It really makes a video impossible to watch. Good luck with your car tho.
@@silverfoxc8Engine will wear out sooner than later. This is why I don’t like buying used cars due to people abusing them like driving them constantly in a lower gear.

I believe it needs to have multiple issues for that. You also need to give the dealer an opportunity to fix it. It is possible though.
