My 2024 Chevy Silverado 11K Miles In Wouldn’t Shift Into Forward or Reverse, Now I Need a New Transmission, But the Dealer Won’t Have Parts For 3 Months Minimum

I bought a 24 chevy colorado, brand new. My brakes failed at 190 miles. It happened when I was leaving my driveway so fortunately I was going slow, but pushing the brake to the floor did very little. I had to pump the pedal to get it to stop and holding the pedal to the floor wouldn't keep it from idling forward.

I live in Dahlonega Georgia i got a 2021 Chevrolet silverado 5.3 engine and 8 speed automatic transmission it runs hot and Jump in gear Been in the Shop 3 Is different time they it was oki its got 63000 mile on it

2024 Silverado Trail Boss 5.3 w/ 5k miles
I have a rubbing/vibration in the driveline between ~20mph and ~42mph, sounds like a groan similar to driving over rumble strips, but it matches the shifts in the transmission. Determined it will go away when I engage the front differential, in Auto or 4H. Dealer is aware and acknowledged they can replicate, but was told they cannot find the issue and it’ll need to get worse to address. This isn’t a turn the radio up noise, once I hear/feel it, it ruins the drive.

I have a 2021 Silverado Trail Boss and the transmission went out, at 60,000 miles, due to torgue convertor, according to the dealer. I had extended warranty and they said they put a new one in it, It did not cost me anything to change. It has been good so far. GM does have issues with the 5.3 L.

I have a 2015 Silverado and the trans shudders, and shifts hard. And sometimes hear it slip. Waiting for a failure.

2021 silverado, just bought used,74,000 miles on it and just started to have problems with the transmission. 2.7 V-4

I have a 2015 Silverado high country. I bought it used with a certified warranty in October 2018. It's been in the shop at least a dozen times for transmission issues. They put a better trans fluid which helped some put a new remanufactured trans in. It still shifts hard and shudders.I know it's a bad torque converter but they won't fix or replace. The last thing they told me is that it is the characteristic of the truck in other words it's normal.

I hope we don't have an issue with our 2015 5.3 Silverado with 97,000 miles, because we just had to replace the engine for a collapsed lifter. And just like their transmissions, they knew there was a problem but did did nothing except produced more cheap vehicles.

2024 GMC Sierra 1500 10k miles , no reverse , limited forward gears. No Parts , no loaner, no help from GM. 30 Days without a vehicle and counting.

I bought 2500 hd 6.6 duramax diesel. It had 65,000 miles drove it 249 miles and check engine went off and it wouldn’t go past 40mph. Had to take it in they said the valve body in the transmission was bad and they had to reset the tcm or something. They replaced the valve body or at least that’s what I’m told.

See it every day !! Needs a 3rd pedal and a shifter, those hardy ever broke, the car makers won't put standards in anymore cause they think we are unable to shift ourselves

Of course GM has swept it under the rug like the problem doesn't exist, all the full while knowing better and not giving a rip. They did the same exact thing with the well known 5.3 issues across multiple models and model years.

I've been lucky si far but now my 3l Duramax has 75k. If indeed the transmission control valve wears over time as my recall notification states, I could be in danger because I drive at highway speeds the majority of the time. Trying to find out who's in charge of the transmission control valve class action lawsuit.

My 21 Silverado was great... Until 77k miles and the transmission died. Waited months for parts, but when they installed the new transmission, it failed. Another two month wait for parts, and now it has failed. My truck has been down since 10/1/24 with several more months waiting on more parts. Although I have zero confidence that my truck will ever be fully repaired.

Rachel should be happy hers was only 8 days mine's 5 weeks sitting in the shop. It won't go in reverse I won't come out of second gear can't go more than 35 mph. 2024 bought back in June 17,000 miles on it setting behind the shop with no end in sight. A $55,000 truck that I paid in full and I can't freaking drive it!

Mine's been 6 weeks, can't go backwards can barely go forwards second gear maybe 35 38 miles an hour at best no end in sight oh but they will give you a thousand points for your inconvenience. $50,000 plus vehicle sitting behind a dealers garage with 17,000 miles on it and I can't drive it no vision of when I can get the parts. Yeah I'm not a happy camper

Had the same problem with a 2021 Chevy blazer with 10 speed transmission. Bought it new lasted around 700 miles then she quit at home no forward or backward went to dealer couldn't figure it out after 4 months had to replace transmission couldn't tell you how it ended up it was totaled few ays later. Good luck with GM🚽

Did you drive it in 4 auto? 🙃
Apparently GM can't make a transmission that runs in 4 auto all the time without blowing up.
Nobody else has a problem with it.

And living in the north having 4auto engaged for 6 months out of the year is essentially a MUST. Haven't seen the pavement on our street since November

2017 Colorado in shop 3 times for transmission problems. Only has 61000 mi. 2 trans flushes and finally torque converter replaced.what's Next.

My trans has been an issue from day one.
U have the new body 2019 5.3 V8 / 8 speed trans.
Delayed response, hard shift, launches Fwd when parking, a vibration, and sometimes a hesitation like a slip. The only thing that Chevy / Dealership has done to address the issue was change the fluid a few times and 'reprogramming' the trans.
I get the feeling they are waiting for the warranty to expire, then I will get the real story, that of course i will have to pay for.

Just had to replace the transmission valve body on my 2023 Yukon XL at 34,000 mi. It started acting up a few months ago and eventually wouldn't shift through gears. I was able to get mine completed in about 2 days though. Seems like maybe I was fortunate.

I have a 2023 GMC Sierra 1500 AT4 w/3.0 diesel. 33000 miles. Tranny started slipping so went to a local Chevrolet dealer. Their transmission guy said 2 solenoids are sticking. He relayed it was a common issue and has killed a lot of transmissions. The parts are backorder with no timeframe. Could be 2 months could be 8 months. Seems odd they have parts for new trucks but not for warranty.

The 10 speed transmission valve body failed on my 2024 Silverado 5.3 at 12700 miles would not back up and only run 45 mph forward
When I went to the dealer and told the service writer what was going on he said immediately it’s the transmission valve body I have three trucks here now waiting on parts, it’s a three month wait
I was on vacation 2k miles from home
The dealer just kinda shrugged their shoulders, it sucks to be you
So i traded and lost money
My thoughts
I have to get home
Vacation is ruined
Spend endless hours on phone trying to straighten this out
NO MORE GM FOR ME!
I really don’t have a problem with a vehicle having a problem but three months waiting on parts is unacceptable

I also bought a 2013 Chevy Silverado from a dealership. Didn’t even have this truck 1 year. This truck only had 70,000 miles on. The transmission blew while driving. Took it to the dealership and they said there was nothing they could do. Not even the 100,000 mile factory warranty would even work. Got rid of it and bought another truck from same dealership. 2023 Chevy Silverado 2500 HD. Jan 2025 not even a year after buying this truck my transmission blew in that truck as well. They had my truck for 1 month. GM needs to get this problem under control. There is obviously an issues with their trucks because I got 2 chevys in 2 year that have bad transmission.

My 2021 AT4 has the 10 speed trans and is on its 2nd valve body replacement. First one at 23000 kms and second one at 39000 kms. My truck has been at the dealership for 3 weeks and counting. No idea when I'll get it back. It's crazy to think my 6.2 could blow up too.

I purchased a brand new 2023 Silverado with the 5.3 and 10 speed transmission in January 2024. At 23,000 kilometers I have had all lifters replaced, bank 1 cylinder head replaced, transmission replaced and I'm on my 3rd torque converter. The transmission still shudders, and the rpm needle has a major fluctuation. The dealership tells me that the truck is running normal and within parameters... That is their go to line when they failed to repair the truck and have no clue as to what is wrong with the truck! NORMAL AND WITHIN PARAMETERS!! GM knows that they are manufacturing and selling crap and they don't care! There needs to be a lemon law in British Columbia Canada, to protect customers when they are sold a piece of shit!
