My guess is the DCT had a problem. They tried changing the batteryand reporgramming the module which didn't fix the problem. They then replaced the transmission.
Is the car a buyback? The previous owner may have lost confidence in the car.

Thanks for your reply. The second owner had driven the C8 about 16,000 miles when the problem arose. The entry from 12/01/2026 is the last one; now the C8 is being offered for sale on 06/05/2026 with 35,953 miles . Does that mean the problem has been fixed since nothing else has been noted? I don’t think it was a buyback.
I don't know the answer to your question - "does that mean the problem has been fixed"

Thank you for your replies. It has been serviced recently. However, it only comes with one key, and the Premium Indoor Car Cover isn’t included, even though it was listed in the description. I’d like to export this C8 R to Switzerland. I’m not familiar with the technical specifications or service intervals. I’d definitely take it for a test drive and have it inspected before buying.
This is the one.

It appears to come with a non-GM pre-owned warranty but any warranty will likely be worthless in Switzerland since the car would likely need to be returned to the US for coverage. I'd have them change the DCT filter as part of the deal since it is overdue, it is unlikely to cause problems if everything works OK after the filter change. But you are taking a risk buying a complex car like the C8 without a warranty.

The response from the garage:
Car is number 665
No second key and no cover but was just recently serviced with oil change.

The fob itself isn't that bad but the dealers sometimes charge a lot for the programming. If you want a second key I'd make it part of the negotiations. I'd also ask them why they are using an aftermarket warranty instead of Chevrolet CPO. If it won't qualify for Chevrolet CPO I'd be concerned as to why. It doesn't look like the DCT fluid has been changed yet and it is probably due so I'd have them change both the DCT fluid and filter if they can't provide documentation that it has been done within the service requirements.
