Sorry to hear your car has transmission problems. Best of luck with the dealer repair and hope this will be the last problem for a long time.

Awful, hopefully you’re not out on the sidelines for too long 😔
That said, are there any statistics out there on C8 transmission failures? I figure this is a case of (rightfully so) vocal minority. The horror stories have done enough to deter me from museum delivery or non courtesy delivery.

Nothing like a P1961 code to end the first time to get the car out for a drive. I took delivery of the car at the NCM with it showing a warning code on the back hatch. Replacement latch fixed that issue. Now with 850 miles I took it out for the first time since I drove it home from the NCM and having it filmed and coated. Started to smell a slight burning smell getting it in and out of the garage yesterday but no issue until check engine light came on after about 4 miles from the house. Took to the dealership to check the code and apparently a P1961 code shows the transmission needs to be replaced. By the '22s I figured the transmission issues would have been resolved. I am so frustrated and disappointed.
You don't happen to have a PDR do you? Might consider grabbing that SD card and checking the contents.

Then 8-10 years from now, we’ll see post after post from the 2nd, 3rd owners of a car with low miles that is “pristine” having transmission issues. The car will be out of warranty and GM will point back to the previously released statement & blame the owner. It’s turning into the LS7 all over again. I do feel bad for new owners who have to deal with it. Good luck with the repairs.

For a regular car I likely would be deterred but I feel like the reward outweighs the risk in this situation. I've never obsessed over a car that I don't even have as much as this one. Maybe I'll sing a different tune if it happens to me. Good luck to the OP for a speedy recovery for your car.

GM will never release those. What will happen is sometime next year or the year after they will release a statement saying they identified a small issue with the machining or supplier that affected less than 5% of all cars produced and it has been rectified.
Then 8-10 years from now, we’ll see post after post from the 2nd, 3rd owners of a car with low miles that is “pristine” having transmission issues. The car will be out of warranty and GM will point back to the previously released statement & blame the owner. It’s turning into the LS7 all over again.

There was another person here that had their car in a shop getting PPF and ceramic coating. When they got their car back they pulled the PDR logs up and saw that the techs in the shop had taken their car out on the road and beat the SNOT out of it with launch control, etc.

Although not PDK, my brothers Mecan had 3 transfer cases: the original failed, the replacement failed, finally a redesigned transfer case worked. He sold it and is buying a C8.

it may be an odd thing to consider but....if it's going to be your car for awhile, and you don't want to get stuck with a five-figure bill (if it ever happens), get the "extended warranty" which is really a prepaid service plan, up front and from the car's mfr---no "seconds"---as in alternate companies that may or may not pay you when the time comes.
1. shop around for the factory-backed service contract. You do not have to purchase it from your selling dealer nor at the time of purchase. Their is a forum sponsor here, Denis Fitchner (check spelling) who sells the GM service contract lower than anyone else.
2. Keep your eye/ear open to issues with major components such as the drivetrain. Small percentage or not, a vehicle that had as extensive testing as the C8 should not be needing transmissions replaced at 850 mi in the 3rd year of production, period.
For example: my wife puts 25-30k mi/yr on her work vehicle. Her current vehicle is a ‘20 Grand Cherokee High Altitude with every available option including very expensive adjustable air suspension. Reading the Jeep forums, there are similar amounts of reports of issues with the air suspension as there are here with transmissions. So knowing she’ll be out of warranty in about 5 months, we’re adding the Mopar MaxCare service plan because I don’t want to pay $5k plus for new shocks if something goes wrong with the suspension. It’s a $2500 insurance policy for the next 70k mi until we trade it in.

Often times you’ll hear that extended service contracts are a waste of money, but there are a few different caveats to that.

Question: what are the odds a bad transmission or other major costly manufacturing defect would NOT be discovered in the first three years of ownership? Looks like most of the bad C8 transmissions are discovered here pretty quickly in first few hundred miles. I realize that’s NOT universal. But what’s the chances you wake up 4 years after taking delivery and say “wow I now know I got stuck with a lemon”..?

Excellent advice, and I agree.

My Z06 just hit 20k mi and is 10 years old. I haven’t had an issue with my LS7 but do I want to risk it and end up needing to replace the entire engine at $15k or do I want to spend $5k for brand new aftermarket heads as a preventative measure? I’m going to spend the $5k on new heads.

Sorry to hear about your misfortune OP. I have read that the NHTSA has gotten involved with an investigation regarding this transmission. Here is the reference to this discussion.

https://www.autoevolution.com/news/c...ay-173055.html
.
The article references GM's technical service bulletin that discusses this problem which seemingly relates to your problem you unfortunately are experiencing. File attached.
.
Please keep the community posted about your status as this issue most likely is effecting many C8s.
