Default Transmission and Engine Modul

Can anyone tell me what these two circled sentences mean? Was the second one the much-discussed transmission that wasn't very good? It's a 2022 C8 R HTC. Thanks

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.

Context? Are you looking to buy this car? Keep in mind that with a replacement transmission, at 27540 miles, the maintenance schedule starts over. That means the filter needs to be changed between 7000-8000 miles since the replacement mileage, so between 34540 miles and 35540 miles, so 35953 miles it is past due for that service. So it needs a DCT external canister filter change now. And the next filter change needs to be 22,500 miles since the replacement mileage. Fluid replacement 45000 miles since replacement or 3 years since replacement whichever if first.

I don't know the answer to your question - "does that mean the problem has been fixed"

I'd assume it was fixed but you'd need to do a thorough test drive to be sure. Is the car being offered from a Chevrolet dealership as CPO (Certified Pre-Owned)? As @Andybump mentioned it is a little past due for a DCT filter change. It is past the window to get a Chevrolet Protection Plan for a reasonable price.

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.

Thanks for the info. I'll ask about it right away. Do you know how much a new key costs?
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.

That's the response I got from Camino. Not exactly helpful. I have time to buy the Corvette. Let's see how long it stays on the market with that Carfax report.🤷‍♂️

Second key they can make for 400 and the vehicle is certified for 12 months and 12000 miles for the one at Camino.
They haven’t done the transmission service yet but all other service is up to date.
Transmission filter was changed when new transmission went in

The transmission was replaced at 27,540 miles, which would have come with a new filter ... correct.

The filter then needs to be changed 7000 - 8000 miles later, so needs to be replaced again between 34,540 - 35,540 miles. This is becasue of the transmission break-in procedure.

After that 1st replacement, it then needs to be replaced again 15k miles later, so around 50k miles .... and then every 22,500 miles after that.

Good point. And, as noted in post 4, at 35953, this car is already past due for the "first" filter change for the new transmission.

Something seems weird with this car in general. The VIN is not resulting in a window sticker. Not only that, but their $70k asking price is way too much for a 2022 with 35k miles and a replacement transmission.

Note the C8.R package is just an appearance package, and doesn't include any additional performance components over a car without the R package. Some may pay more for that, but there's really nothing different from a normal C8 other than the graphics and colors.

I'd be looking for a different vehicle, unless they're willing to negotiate significantly below $70k.

I'd also want to see the window sticker, to confirm it really has a C8.R VIN and isn't just graphics someone put on it.

Never mind about my comment about the DCT fluid change being needed, I forgot about the transmission replacement when I said that. It does need to have the filter changed.

Good to see it has the real C8.R package. It was $98,140 MSRP when new (without destination shipping charge). If this were low mileage (like 7500 or less miles), and didn't have the transmission replacement on the carfax, I'd expect it to be about 75% of the original sticker price. So $73,605.

But with the high mileage, and of course the trans replacement (which is now over due on maintenance), I think this car should be in the low $60's ... just my opinion though.

Thank you for your reply. As an official Chevrolet dealer, you should know this, but if you’re not willing to help, I’ll look for another one. But it’s really frustrating. I’d already contacted another dealer and told him I still needed to check when the transport company could come. Then he sold the Corvette without even letting me know! Apparently, your word doesn’t count anymore! They just want someone to come into their office, take out a loan, and make enough money that way. They won’t make much off me, but I’m sure I’ll find another dealer who’s willing to make a deal with me.

Thanks for your opinion. I offered 63K. He said they’re rare and come at a price. There are a lot of fake C8 Rs out there, so I always ask for the number on the plaque between the seats. One guy already acted all dumb, saying he couldn’t open my photo or didn’t understand what I meant. 🤣 car number is 665.

Just so you have an idea of what a C8 R goes for here in Switzerland. And that’s without a warranty! A gray C8 R HTC was listed for 137000 Swiss francs. That makes me think of only one thing: the Swiss are crazy. 👋🤣🤪
