Just ranting on why GM hasn't addressed/fixed the transmission problems on the C8 over 4 years since it's release?
I am currently waiting for my dealer to get my transmission in to replace but it will be replaced with a transmission that has not been revised and may end up with the same problem down the road. In some cases, Owners have had it replaced more than 3 times?
I have always wanted a Corvette since High School many many years ago. I was lucky enough to get a C7 in 2014 and have owned (4) C7's since then including two Z06's. I purchased a 2020 C8 in 2020 later sold it for a profit and in 2021 purchased my 2021 C8 and it is now turning into an unreliable nightmare?
I absolutely LOVE this car but the reliability issues are really starting to be a concern! My last two car shows I had people say "Beautiful car, have you had any transmission problems" So the bad rap is out there on the C8 Corvette and apparently all GM wants to do is sell more. Today with the Z06 and future ZR1 these unchanged transmissions I predict will drop like flies? GM needs to get their heads out of their a$$ and address the problems and fix them, period.
I'm done ranting. Sorry.

I can't help but to wonder how out of warranty cars are selling. Or is the 5 year power train warranty still protecting owners and transferable unlimited times? I'm thinking and out of warranty failure could easily cost 1/2 to 1/3 the value of the car, only to fail again.

2024 C8 of the Year Finalist - Unmodified
I feel for the owners experiencing DCT issues.
Luckily for me, it's all been happening on the forums. Not one personal experience associated with anyone I know.
GM probably doesn't think there are enough "issues" with the unit conduct a redesign or make a modification.
Hope they fix it soon man.

Rollo, did I mention I love this car and I'm just disappointed that GM is letting the Corvette Name down by not fixing the problem.
Years from now it will be Covette C8's were sure pretty and bad to the bone but they had transmission woes!

If you only read the forum where all kinds of problems are discussed, you will think all C8's have transmission problems. Of the transmission failures, probably most are covered in the drivetrain warranty. I can understand it being a bummer being without your car while waiting for a new transmission, but it could be a whole lot worse if you had to pay the 18K for a new transmission.

Pitiful, I agree... and, I feel for your situation. However, this isn't the only recurring problem for Vettes, some even across series. It would seem that GM just fails to learn from past experience.

I find it hard to argue with you - GM has consistently failed or at least has been slow to address problem areas and this goes back a number of generations. Granted the problems presented on the forum get more attention since owners that have no problems tend to just remain passive about their ownership experience. But that does not take away from the fact GM should be more proactive in addressing customer concerns.
When you spend the kind of money that the Corvette costs, you would hope that the car would be very reliable.

They have made several transmission improvements since the car was introduced.
Have those helped? Are new ones more reliable than the first??
We really don't have any numbers to prove anything. Are the new ones any better?
How many have actually failed? What percent.
We hear about the bad ones on this forum. I wonder how many people are driving trouble free?
I have a 2023 with 7K miles, no problems yet.
It is a bummer to hear about such a complex machine failure since there is absolutely nothing you can do about it.

Since the pricing equation has changed and people are not standing in line to pay over sticker, we seem to have more and more people on the forum wanting to denigrate the car and the manufacturer. I am really beginning to wonder why anyone bought the car to begin with from what has to be the world's worst manufacturer.
In my career, I operated dealerships representing more than a dozen different vehicle producers. They ranged from VW to Rolls Royce. I also had mainstream cars such as Ford, BMW, and Cadillac. One thing was consistent when you were around these cars continuously. They all had problems with certain components in models across the board. Even Toyota had a period of time where they were losing engines seemingly daily. If you really think somehow something like a run of transmission failures is somehow unique to GM...you just haven't been around much. I have seen them all have runs of problems and be no more or certainly even less reactive than GM.

I will not name names here but when I found out my transmission needed replaced, I asked the Mechanic if they thought I should trade it in on a new one?
He and the salesman both said "They all can do it even the new ones" "We just had a 2024 with 400 miles need a transmission" This tells me GM knows of this problem and it is growing every day? The problem here is not that GM won't fix it, the problem is the fix is not a fix, more like a band aid until the next failure. I want to drive this across the Country but have a worry that it may break down in the middle of nowhere!
