Also, I suspect autos in these cars are tuned for firmer shifts. An auto that shifts "like butter" is just slipping more before the shift is complete.

That idea implies that this is normal. It is not. It is not harder shifts. The problem is that it is not timely downshifting to the correct lower gear, which causes (i) pulling at a stop while it downshifts too late into the correct lower gear and (ii) hesitating for a very long period of time when I slow down and then accelerate while it tries to get into the correct lower gear too late for acceleration (often slamming into the gear and while the engine refuses to accelerate until the car is in the correct gear). What good does it do me driving a car without the problem? It is not like this is subtle, normal, not a big problem or it is just in my head or me nitpicking. I know a lot about cars (used to build motors, etc.). I am not some clueless young kid who gripes about everything. Thanks for the idea, but as you can see I am very frustrated.

Somebody above asked "what did the dealer say". Bottom line is that they told me that only one of their transmission specialists can look at transmission problems, a transmission specialist cannot tell what is likely wrong with it by just driving it (they have to take it apart), they are booked up for weeks or even months, they have a lot of vehicles on the lot waiting for transmission parts that are hard to get, and that I would probably have to leave my new car there for weeks to have it looked at. I said no thanks. It sounds like those countries that have free health care but good luck ever getting it (there is a long wait and line). I have a warranty but they are going to make it very difficult to ever use it. I expected to be treated better by Chevrolet. I called a couple of other dealers here in San Antonio, TX and they said the same thing. Some of them did ask if I bought my car at their dealer (implying that I would only get service if I did) and they did not care that nobody (including them) had these cars in my area when I purchased it in September of this year (had to travel to another state to buy it). They do not seem very bright, but I expect that from people nowadays. It's like when I went to Home Depot and asked the man in the tool department where the feeler gauges were located at and he did not know what one was even though they sell spark plugs for mowers, weed eaters and blowers (no spark gap rings either).

Right now I am driving it trying to figure out what to do next. One of my ideas is to go to a dealer and insist to talk directly to a transmission specialist. The general service guys are of no help.

I put $500.00 down on the car when it showed "in transit" on the Chevrolet inventory website for a MSRP deal (and no dealer added options). Dealer told me I could get my deposit back if it does not arrive in 2 months, which will put me in the middle of this month. If it does not arrive by then, I am leaning toward just cutting bait and moving on. I am losing interest and wondering if the whole idea of getting a Camaro "toy" (a car I do not need and will not daily drive) is a foolish idea. I knew it was somewhat foolish, being the practical, frugal, conservative guy that I am, but I went against my nature to "live a little" and get another muscle car like I used to have back in the late 70s (grew up with the real deals) for the nostalgia that I crave. Oh well.

Auto has a higher resell because there is more demand for them as most people either cannot drive a stick or they do not like to drive a stick. Plus, the 10 speed auto is pretty special. Autos outsell sticks (for any car) for a reason; more demand for them and econ 101 higher demand means higher price and lower demand means lower price. Most salesmen are either liars or they plain do not know what they are talking about.

You have had quite the journey to go from a 2022 1SS 1LE M6 to a 2024 1LT A10. Sounds like you would have been happier with the 6.2L V8 and M6 transmission. Hopefully it gets sorted out for you.

I tried to buy a new 2022 1LE M6 in 2022 (put money down on one "In Transit"), but after 8 months of endless delays I finally cancelled my place in line and got my deposit back.

I would actually be happy with an 10 speed auto that is not defective. I love automatics as well as manuals.

I probably should have just gotten a M6 if I had known I would get this defective 10 speed. I have no problem with a M6 other than resale, and the M6 would have the benefit of a limited slip differential and without AFM cylinder deactivation.

Thanks for you kind comment and thanks to the other folks who commented as well. I think I have about beat this issue to death so I will just report back when I finally get it repaired one of these days. My bet is that it is the TCM.

UPDATE!!!!

Bottom Line: I bought a brand new 2024 Camaro with a defective transmission as confirmed by my dealer today. This is from the Chevrolet dealer:



I started this thread about a week after I bought my brand new 2024 Camaro. See the first post in this thread. The car now has 3,500 miles on it. I tried to tell folks on this thread that the transmission was bad, but most of the folks on this thread doubted me and thought I was just overly sensitive with my complaints and that what I was describing was normal. I even started to second guess myself in this thread, thinking maybe it had "cured itself", etc. As is often the case on these types of boards, there are a lot of "fan boys" that won't admit problems with whatever they are a fan of (in this case the Camaro) and even attack or try to illogical rebut those who have legitimate complaints.

As shown in this thread, I tried to take the car to the dealer after I bought it and all the dealers told me I would have to leave it for at least 3 weeks to even have it looked at (and at least a couple of months if it needed repair which I knew it did) because there was a very long line of customers with transmission problems, the transmission mechanics were "booked out for weeks" and they could not get parts or new transmissions. I was not willing to let my one week old new car sit for 3 months or longer on a dealer lot because I have had dealers damage my cars in the past. So I did not drive it much and waited and hoped the line would get shorter and the parts and transmissions would become available. I waited several months. I called a Chevrolet dealer a few days ago and they told me they could look at it within 2 days of me leaving it at the dealer. The above is what they found today. Metal shavings and a bad pump FROM THE FACTORY.

The dealer is trying to make me take the car back with just parts replaced even though metal shavings have been circulating in the transmission for 3,500 miles and obviously the pump has not been circulating the correct amount of transmission lubricant to the transmission parts and the transmission has been slamming into gears and slipping . I am insisting on a new transmission and I will die on that hill.

I am also going to explore the lemon law. This has obviously hurt the resale value of the car because it will come up on CarFax reports. Nobody wants to buy a car with prior transmission problems. I regret buying the car now.

Glad to hear you got a defect fixed!

Not sure that gives cause to bash people here who were trying to to be helpful. In my experience, folks on this forum go over and above to share their knowledge based on what other users report. To be fair, I don't think a whining pump or rattling under the car were among the symptoms you reported previously in this thread...



You gave a litany of other symptoms, some of which sounded like normal operation of an A10. Time will tell if those symptoms are still present or not after final repairs are completed...

You had a very specific, uncommon issue with your car. Coming on here and calling people "fan boys" because they couldn't diagnose your complicated issue isn't going to win you any points. In reading back over this thread, I think there were a lots of ideas given out, some maybe not so helpful and a couple that were downright sarcastic. But there were a a lot of knowledgeable people putting forth ideas and suggestions, trying to be helpful. I find that the users on this board, and many other Camaro (and f-body) boards were much more knowledgeable than the general public on Facebook. On Facebook, you never know if you're getting a good answer or not. Here, the answers are much more trust-worthy, and if not, they'll get called out and explained why.

I never told the dealer there were any rattling noises because there were none that I heard. I also never told the dealer about any whine, even though there was some slight whine occasionally for about 2 seconds from take off from a stop. I told the tech that checked my car in (who is not the transmission tech) the exact symptoms that were in this thread and I watched her write them down. Why the transmission tech came up with different ones I do not know (but see below).

The main purpose of the transmission pump is to shift the gears in the transmission through the valve body, and thus all those "litany of other symptoms" I have in this thread are caused by a bad pump and those symptoms are the main symptoms when driving the car. There are no other issues that are not tied to the bad pump. The whine and any other noise are not the main symptoms (Those are what a tech hears when he puts the transmission under load at an idle.).

I wrote a long rebuttal to the complaint that I called some people fan boys, but I deleted it from this post. It is not relevant at this point.

By the way, it is not fixed yet.

It is not as uncommon as you may think. I did a search on the internet and these pumps are going out frequently because of a bad gear design for the pump. You are going to start seeing more of this in the very near future. SEE THE POST BELOW FROM ME.

All the people on this board saying it's only the 8 speed auto that has problems and that the 10 speed auto is good are in for a very rude awakening at some point during their ownership if they have the 10 speed. If you own a Camaro with a 10 speed auto, I wish you good luck.

Once that pump gear goes out, you have metal shavings in the transmission, transmission cooler and lines and the torque converter, and an auto transmission flush does not get all of that out, especially the torque converter. Even if you replace the transmission, you have metals shavings in the torque converter, cooler and lines that will go into your new transmission. It's a mess.

There were very few of the comments that were meant to be helpful or even attempted to be helpful. Most of the comments were from fanboys to try to discredit me (e.g., its normal, you must just not like automatics, etc.). Those guys get irritated if anyone speaks of Camaro problems. They are all over this board and most ever other board of every type of subject. I called them fanboys because that is what they are and it is obvious from reading their comments.

Here is a small sample of this problem being a major defect in the new 10 speed auto:

https://static.nhtsa.gov/odi/tsbs/20...39046-0001.pdf (It states improvements to the pump drive gears were made in 2022, but they must not have been good enough improvements because it happened to my 2024).



https://www.transmissiondigest.com/g...ew-pump-noise/ (See this link)

Interestingly, I read that the Ford version of this transmission does not have this problem because Ford designed the gear with "straight cut" teeth. However, GM wanted a quieter transmission, so some GM DEI engineer changed the Ford designed gear to have slanted teeth for GM 10 speeds which causes the problem by putting too much side pressure on the gear bearing assembly, which it was not designed for, which causes the gear bearing assembly to fail, which causes the gear damage and ultimately the pump to fail to work properly.

Thanks for the heads-up. Hoping for the best of luck with my A10. Is this related to the transmission control valve recall issue, or is this a whole new issue? I watched a friend install a Trans Go shift kit in my 4th gen Camaro many years ago (twice, 2 different transmissions), and he briefly explained how the transmission worked. Didn't make any sense to me, lol.

You're most welcome.

It is a separate issue. The transmission pump is driven by two gears, and the issue is that the bearing that one of the gears rides on goes out because that defectively designed gear puts too much stress on the bearing, and once the bearing goes out the gear no longer runs true and it grinds against the second pump gear and chews the teeth off the gears. Then you get what I wrote above and have been posting for months in this thread. That video that I posted above explains it pretty well and visualizing what is going on helps a lot, probably better than I just did.

An important point that I have made in this thread is that my car came from the factory with the bearing problem (or it happened within a very few miles - 10 or less). In that respect, my car is very unique as most of these problems show up later -- not from the factory. I noticed it almost immediately (certainly within the first 10 miles) when I drove away from the dealer when I bought it. I honestly think I noticed it when I left the dealer parking lot, but I am not certain (hard to remember for sure). I bought the car at a dealer about 1,200 miles from TX and so I was not about to just turn around and go back to the dealer on my way home to TX (I was on a time schedule), and I convinced myself that it may be something that would fix itself, etc. After all, the car was brand new. Who would have thought a brand new car has a bad transmission? Basically unheard of IMO. Come to think of it, maybe that is why so many people on this thread questioned whether there was anything really wrong with it since it is unheard of for a new car to have a bad transmission. Apologies to the mislabeled fan boys.

I saved that video to watch after work today. I'll definitely watch it (why not, it's short!).

I would say that's probably a large part of the reason that you were doubted. Good thing they got it figured out, and hopefully it'll be 100% covered.

It is 100% covered under the warranty, but Chevrolet only wants to replace the parts and not the entire transmission. I could fight it and probably win with enough effort, but I can make a lot more money with that time doing my day job, and so I am going to let them repair it and then sell the POS to Carmax or one of those places and cut my losses before something else fails on it or the transmission fails again with this half-ass repair. I will never buy another GM product again. I honestly don't know what I was thinking buying this car. I have bought nothing but Toyotas for many years now and I have never had problems with them and they hold their value (My current daily driver is a Tundra that I bought new and it will be 10 years old in September with no problems and it is in like new condition.)

I now just want them to hurry up on the repairs so that I can dump this POS. I will lose about $8k to 10K including taxes and I am lucky it won't be more. The car has 3,500 miles on it.

[TexasChile]

Another Update:

1. The dealer is going to put a brand new transmission in my car and it should be done by the end of the month.

2. I now think that this is not a design problem with the transmission and I think most cars will not have this problem in the future. I think GM got some bad bearings or the bearing my have been damaged during assembly. The reason I think this is because my buddy who services around 100 trucks for a large contractor told me that he has 10 Chevy trucks with the same transmission that have over 100,000 miles and none of them have had this problem, and he confirmed the same with his friend who is a service manager at a Chevy dealer that he works with. So that is good news for folks on here.
