Default Transmission issue - Sell or keep?? - HELP!

Hello Everyone!

I have a major conundrum, and I would like as many people s opinions as possible!

Last year, I put an order for a C8 Corvette, 2LT coupe at two different dealers in New Jersey. After a 14 month wait, I got my car from one of the dealers. That was a month ago. Was absolutely loving it!

Now for the bad news:

after driving around for less than a month, 760 miles later, my check engine light came on as the car was down shifting very weirdly. Long story short, after taking it to the dealer, the car needs a new transmission! As much as I understand that transmissions have been a problem for.corvettes, for whatever reason, it still sucks having spent so much money for a top-of-the-line sports car and this still happens to you.

Everyone I have asked has reassured me that the transmission will be a brand new, original GM part and when I get the car back, it will be as good as new! But is this truly the case? If a problem of that magnitude happens so soon, could this be indicative of more engine problems coming down the pike?

Now here’s the twist:

for various reasons, I have still not canceled the order with the other dealership and I think my turn should be coming up soon…

So here’s the question:

is it worth placing an order for a new Corvette and privately sell mine after it’s been fixed?

Here are the caveats:

If I go that route, I will definitely need to sell my car first, pay off my current auto loan, before I purchase the new car. I can’t get two separate auto loans that would overlap.

On the flipside, I would hate to sell my car too quickly, and then waste the whole summer, waiting for the new one… We all know how this can go.

finally, if the new car arrives at the dealer and I have failed to sell mine, I would have to kindly refuse to pick up the new vehicle. I can do that, right? Would that put my deposit with the second dealer in jeopardy? Can they be as**holes about it because I walked away from the order and now they’re stuck with the vehicle?

or is this all a big hassle and I should just stick with my fixed car with its new transmission? (At the end of the day, who knows what the new car will be like, right? )

And how about its resale price? Would having changed the transmission affect it??

Thanks so much to everyone taking the time…..

The transmission will be a brand new one. I would just have the car fixed and keep it tbh.

Oh, and your deposit will DEFINITELY be forfeit if you 'walk' from a sold order after the fact.

Default 2023 C8 - shavings in transmission cap

Is this normal? I just change my transmission filter (miles: 6145) and i swear i can tell a MAOR difference in how it shifts.....feels like showroom again. I will be modifying the plate that covers the filter housing (dang taking all them screws off just to change that). I will cut up out so next time, it will be right there exposed (pic and video to come).

BUT, i noticed when removed the filter cap, i saw dark gray shavings (idk, yall tell me). I dont know how to feel about this....is it normal, not normal, etc. For a new car with 6k miles, this seems odd. Any thoughts?

Being extremely concerned, I immediately brought the car into the dealership the next morning. I was told that "some" C8s have had tranny issues straight from the factory stock. I was told by the dealership that this could be a multi stage fix / process. Starting with a Tranny flush and clearing the code and if that didn't work the valve bodies would need to be replaced. Lastly, I was then told if that didn't work then I would need a brand new transmission for my brand new car. WHAT???????? I was floored when I heard this as you could imagine and started all my research and due diligence on the internet researching this issue and if or how common it was. Obviously, I found out this was very common and many people have gone through this. I immediately opened a case file with GM and have been carefully documenting everything since this all first happened. GM has been good thus far but needless to say the first 2 steps didn't work and the car is now back at the dealership getting the new replacement tranny.
Obviously I am furious and very frustrated with this whole situation and am looking for any guidance and/or feedback & suggestions. I have even opened up the discussion with Chevy/GM to repurchase my car.
Again, very upset & frustrated and any and all comments, feedback and suggestions are welcome and would be greatly appreciated, thanks...….
multi-stage process is a good way to describe it. Many of the transmission related diagnostic procedures go through a list of attempted remedies, checking after each to see if it solved the problem. It includes first checking the fluid level, then the Hydraulic System Flush (an internal process that is initiated by a scan tool, while the car is running, takes 8 minutes), replacement of the DCT external canister filter, drain and replace fluid. Often the last step is removing the pan, cleaning the pan and magnets, replacing the internal filter, and refilling. Sometimes there is a valve body replacement in the mix. When all that fails, they replace the transmission.
