General Motors has released a Customer Satisfaction Program for select units of the Chevy Silverado, Chevy Camaro, Chevy Tahoe and Chevy Suburban due to an issue with the transmission.
Tagged with CSP number N232409730, certain 2023 model-year vehicles may have a condition where the pinion gears in the GM 10-speed automatic transmission have low core and surface hardness. To rectify this issue, certified GM technicians have been instructed to inspect affected vehicles and replace the transmission as necessary.
According to a GM spokesperson, there are only 326 units affected by this Customer Satisfaction Program across all the brands and models. Notably, this includes a few Cadillac and GMC models as well.
Meanwhile, the following 2024 model year has seen a few notable updates for all the Chevy products listed above. In regard to the Silverado 1500, the changes were fairly mild, with some shuffling of paint colors, the addition of a new set of running boards by way of the power retractable black assist steps with LED lighting (RPO code B3L), and a new Rear Seat Belt Indicator. As for the powertrain, the Duramax turbodiesel 3.0L I6 LZ0 engine is now offered on the off-road-focused Silverado ZR2 trim level, while the 6.2L V8 L87 is equipped with a Dual-Model Exhaust (RPO code NPP) feature.
In regard to the 2024 Tahoe and 2024 Suburban, the Bow Tie brand’s full-size SUVs saw a single change, namely the removal of the Auburn Metallic (color code G48) paint color. Of course, the Tahoe and Suburban are gearing up for an all-new generation for the 2025 model year, so stay tuned.
Finally, the 2024 model year stood as the final year for the iconic Chevy Camaro, as General Motors has officially sunset production of the Bow Tie brand’s sixth-generation muscle car. For its last victory lap, the Camaro was offered with two limited-run packages, including the Collector Edition and Garage 56 Edition. Looking ahead, the Camaro may make a return, however, it would likely transform into something else entirely.

I remember decades ago Rolls Royce used GM automatics because they were the best in the industry. GM needs to go back to its roots.
They Are the best in the world. You don’t hear about Toyotas rapant issues with their new 8-10 speeds because it’s Toyota and it’s considered “normal growing pains” the 9-10 speeds have had very few issues, and most of the issues reported were Supplier part related. The 8 speed Has had no issues after the fluid was resolved. The 6speeds are still some of the most reliable out there.
On the other side, the ZF and Aisin transmissions have their share of problems and require way more maintenance than the GM ones, but it’s expected from the OEM’s that identhese transmissions, so a valve body rebuild/converter swap is a welcome repair if it happens at 150K instead of 80k
Steven is trying to fool himself.He should stop being delusional when he says the Aisin Automatic has more problems than the and need more maintenance than GM Automatic Transmissions. The real fact is the other way around.
I got an Aisin HD transmission. It’s clunky, requires tons of preventative maintenance. My farm truck Chevy meanwhile refuses to die. I expect to rebuild the Aisin at 150K. It already has questionable shift quality. So what I speak of is experience. Friends and family confirm, the 6L80 is bulletproof. Ditto 6T40/6T55/9T60. There’s no issues with the 8 being reported past the fluid. And even then it only effects the converter. Be a good time to buy an 8 just because you can negotiate more off it .
What about the crap transmissions on the older Chevrolet vehicles.. my 2016 doesn’t even have 120,000.. miles on it ..I’ve only had it 2 yrs…it crapped out ..come to find out ..this is common problem in certain years…of Chevrolets.. but Chevrolet isn’t standing behind their product ..or recalling any of them… With as much as these vehicles cost…that’s crap…and crappy customer retention policy..for sure .
I have a 2019 Chevy silverado with the 8 speed transmission .Less than a year ago I replaced the tork converter because transmission was jumping and lungging, grabbing shifting up and down while taking off now I think it’s going out again . I’ve heard that there is a problem with the transmission but Chevy won’t do anything about it. I love my truck it has the best ride but I’m thinking of of going to Ford because my brother never has any problems with his new truck. I’ve always had Chevy silverados maybe it’s time for a change if Chevy won’t take care of their customers that’s been with them for 30 years
2016 silverado 8spd 2500 HD 89k had to rebuild transmission. Spent 4k doing it. Drove silverados my whole life. Never had a tranny go before with less than 120k. Very disappointed. Love my truck but this has made me rethink about buying another one anytime in the future.
Steven,
Are all of us who had problems with our GM vehicles just making this stuff up?
While you’re the consummate GM apologist, I strongly suggest you listen to what people are posting here. GM is really turning out low quality, problem vehicles, and your blind praise isn’t going to address or fix any of that.
When most of us leave GM for good, you’re going to sound rather pathetic in your ‘GM-is-great’ echo chamber.
Mary says “blow up GM’s past, and its heritage”.
She’s accomplishing that one failure at a time….
GM should issue a fix for their horrible 8 speed. It’s called a 10 speed retrofit.
Steven the fluid didn’t resolve the problems . My 2022 Colorado has all these issues, stop the bs, Jake b. Has it right.
Converter shudder? That was the only reported issue with the 8. I’ve driven dozens of 8’s as rentals. There is no issue with the converter shudder in anything up to 40K. Sounds like you need to get the fluid changed. I recommend Valvoline full synthetic, well, assuming you haven’t ruin your converter
It resolved most problems, especially if caught early. After if it went too long then there was torque converter issues in a small batch and then a minute amount has transmission failures, usually from neglect of replacing the transmission fluid early enough. So yes, it does resolve the problem most of the time, but not all…
Bs the transmission were s*** out of the gate brand new transmission failing had nothing to do with fluid or how anybody drove them you installed junk you took the lowest bid and that’s what you did just like Harley-Davidson and look what that done to them well branded but still the most ill-fated piece of s*** that you can ever ride more of a popularity issue Chevy is going to be left in the dust if they don’t get on top of this soon I’m the fourth generation Chevy owners and I can tell you if the problem doesn’t get fixed and we don’t see some reimbursement I’ll be the last generation to own them
No, TMI is spot on. The original 8 speed was golden if you got the fluid changed ASAP. If you waited, or bought it used and the prior owner didn’t do the fluid change, chance was the converter already had irreversible damage.
Not unique to the Chevy 8. You take an older Toyota Camry auto, put newer thinner fluid in it, and you’ll leak past seals and dry them out causing slipping, which can’t be fixed with the proper weight fluid being added again. Many out there on the road with flawless 8’s. If your is crapping, don’t panic, find a local GM tranny specialist, get the converter replaced for 800-1000$, and a fluid flush and your golden for 200K. FYI, I recommend valvoline. I found it smoothed my aisin from feeling like a dodge shift quality to closer to the older GM 4 speeds.
Now there is one caveat to the converter shudder where it pops up unexpectedly. If you bought one used, the prior owner might not have experienced the shudder if they ran their tranny hotter, or were in a more arid climate. The shudder is caused by water suspension in the fluid, changing viscosity and causing clutch material to expand. If you’re in a dry climate or the tranny temp is above 200 frequently, the fluid stays dry. If those conditions were to change, an otherwise good tranny starts showing shudder issues.
So how does one determine if their 10 speed equipped 2023 is covered by the csp?
Of course GM is issuing a recall there’s only 326 units affected!
Even with the class action lawsuit in process likely won’t be any official 8 speed transmission recall for the needed triple flush and synthetic ATF replacement resolving the lurching and shuttering issues. Reason? Cost. The 8 speeds problems affect a significant number of GM vehicles over several production years. Typical GM BS.
Power train warranty service is hit and miss thru the dealer.
I’ll live with it for now. Eventually I’ll likely pay the $400+ cost to my dealer to have the needed triple flush and fluid change service performed at the appropriate mileage maintenance interval due in another 15,000 miles.
2010 has the same problem with the rear end to mine been rroanin since new
Steven my 2022 Colorado has 5,000 on it. I shouldn’t need to have my transmission flushed, it’s a junk transmission, has not shifted correctly since day one and cold temps seem to make it worse. So what happened with the new fluid was supposed to correct things, not true. Gm should extend warranty on theses things to 150,000 and maybe I will be a repeat customer.
GM doesn’t build qaulity anymore they have too many cooks in the kitchen. Most of their products are more foreign than domestic. They just test them on the consumer & watch them fail.
I have read much about the 8 speed , GM has settled a class action on those. I have the six speed and have read many complaints about it also. I am hoping GM will step up and recall them. This was my first Chevrolet truck, and may be my last if they don’t stand behind their product.. we should generally expect the transmission to last as long as the vehicle
Yeah my 22 shifts odd and I feel like im driving on borrowed time have 72k miles.. and out of warranty….
I believe I might be affected by this.
I hear a humming noise on the back, which sounds a lot like a pinion bearing issue. Car has less than 2k miles
It’s 2024, even society has tranny issues.
