As a follow-up to a recently issued Safety Recall, GM has now published a Special Coverage bulletin for certain units of the 2020 Chevy Camaro, the 2021 Chevy Camaro and the 2022 Chevy Camaro that may be affected by a momentary wheel lock-up problem caused by a defective transmission control valve that wears much faster than it should.
The Special Coverage program for the Chevy Camaro bears the identifying number N242480631, while the GM Safety Recall it references is identified as number N242480630.
As a reminder, involved Chevy Camaro units are equipped exclusively with the optional GM Hydra-Matic 10-speed automatic transmission. These transmissions were built with a defective transmission control valve that wears out rapidly, causing pressure loss that results in harsh shifting, and eventually wheel lock-up when downshifting from eighth to seventh gear. Though the lock-up is only momentary, it happens when the Camaro is driving fast and can cause an accident or a crash.
The Special Coverage bulletin reveals that when the previously installed software – which detects excessively rapid wear of the control valve and limits the Camaro to a maximum of fifth gear approximately 10,000 miles before lock-up would occur – signals the presence of excessive wear, the control valve body is to be replaced by GM dealership service personnel.
The Special Coverage itself extends the availability of this fix for affected Chevy Camaro units to 15 years or 150,000 miles, whichever occurs first, from the previous 10 years or 100,000 miles. The fix is offered free of charge regardless of the current ownership of the Camaro. Owners who already had the fix applied before the free-of-charge coverage are likely eligible for reimbursement. Dealership service personnel will replace the transmission control valve body plus associated seals, filters, and 9 new quarts of Dextron ULV transmission fluid.
Notably, this issue potentially affects three of the Chevy Camaro powerplants for the involved years, the naturally aspirated 3.6L V6 LGX gasoline engine, the naturally aspirate 6.2L V8 LT1 gasoline engine and the supercharged 6.2L V8 LT4 gasoline engine, all of which were optionally paired with the involved 10-speed automatic transmission. Camaros motivated by the turbocharged 2.0L I4 LTG gasoline engine cannot be involved because this was mated to the GM 8-speed automatic transmission instead, which did not include defective valves.
For reference purposes, 50,147 Chevy Camaro units are included in the recall overall across the United States. As a reminder, the Chevy Camaro rides on the GM Alpha platform under the sheet metal. Production formerly took place at the GM Lansing Grand River plant in Michigan.

So I know some people are going to say why not just replace the valve, well they don’t have enough stock to do that to all of them. This is a fail safe idea so they can build up stock and when your car gives you the code the parts will be available. They have close to a million of these 10 speeds on the road and there is no way they can replace them all right a way. They are also extending the warranty so it should give many people some relief to know it will not cause a accident and you can get the part replaced once you get the message.
Wonder if they will send out notices to Camaro owners, since many probably don’t follow this stuff very closely??
I just got mine back after over 60 plus days at the dealership for transmission problem 2024 Black Panther Edition!!
Cheapest parts from lowest bidders with little quantity control at all brands these days it seems. Sad.
I saved and paid for a 2022 ZL1 Camaro and mostly take it to car shows. Seldom do I drive it on the Interstates, has 12800 miles, and I drive it with respect. Gee I hope I don’t get involved with this transmission thing in a bad way.
If you’re hoping to sell it and retire from the profits, think again. I bought a new Cadillac CT5 in 2022, and I’m going to drive it until it dies. Just like I did with my Pontiac. I currently have 56K on it, and drive it everywhere and every day. That’s why I bought it. Not to take it to car shows.
If it is a 1LE you should not be affected by this recall as your transmission is a 10L90E (not the 10L60,80,90)
Can we expect GM and Cadillac to expand this Extended Transmission Control Valve Warranty to the Cadillac sedans impacted by the original recall, which only calls for the software “patch” that alerts drivers to the potential lockup problem within 10,000 milles of possible occurrence? I am the original owner of a black 2020 Cadillac CT6-V with only 5,900 miles so I’ve been watching this issue very closely over the last 2 weeks and have been very concerned about GM’s handling of and dealing with the actual part problem…the defective transmission control valve. Assume that since this is still early in the actual recall process, GM will be getting around to doing the right thing with the impacted Cadillac owners too, and not just the Chevy owners. Please advise if this sounds about right and potential timeline. Thank you all.

At the top of tis article it says “Camaro units are equipped exclusively with the optional GM Hydra-Matic 10-speed automatic transmission” Then says the LT4 has it. The LT4 Camaros have the “Supermatic LT4 10L90E 10-Speed Automatic Transmission”. As usual, clear as mud. I have a 2023 ZL1 A10 so I guess my model year isn’t involved, even if I had that transmission.
how many miles
