Good news that GM and your dealer is taking care of you.

The delayed engagement (the technician called it a double engagement) generally only happened when the car was started first thing in the morning. It usually lasted until the car came up to operating temperature, when the warm up band on the tach went away. But, sometimes, I would get a delayed engagement when driving. Making a turn, coasting around a corner, the transmission would sometimes delay engagement and thud into gear when starting acceleration (even light acceleration) after completing the turn.
As I mentioned before, I've already had a new torque converter replaced under warranty. That seemed to solve the problem for about 5,000 miles or so, and then it came back, even worse than it was.
I think the reason I'm getting the new transmission is: 1) a dealer has already tried two fixes and 2) I switched to a better dealer.
Updating what's happening now, a new transmission has not been delivered and we have the holiday weekend. I'm guessing it won't be shipped until Tuesday, if I'm lucky, and I may not get the car back for another week.
I'll let you all know.
Thank you for all your interest and support. On the positive side, I've had the car since October 2014; driven it for over 20,000 miles, and love driving it! I've been to several racing classes including Spring Mountain and this corvette is really the best handling and performing car I've owned. I can't wait to get it back!
Take care all,
Phil from Georgia

Man, this is too bad about the A8.
Good luck OP. I hope the new transmission takes care of your problem.

Hello all!
I just wanted to let youall know that it's possible to get a new replacement A8 if you are having problems.
My transmission was diagnosed with double engagement ( I had that hard shifting problem in the morning that some of you have also had). The dealer has ordered a new transmission for me, and I should receive it sometime this week or early next week. I've had this problem for a long time, and a different dealer tried a software upgrade and a new torque converter and neither of these fixed the problem . So now with a new transmission I should be able to start enjoying my Z 51 again!
I took delivery of my car in October 2014. So it was a early production transmission. I'm hoping that this is a 2016 transmission and that it will be better.

The transmission and torque converter rebuilders for GM must be working overtime to fill the orders When GM is selling between 30k and 40k cars a year whats a few defects going to do to their bottom line, probably not much. Trade in time will tell the story.

Only issues my trans had was the delayed engagement. TCM update fixed it for a month, then a new transmission (#24274892) fixed it for another month, but it's doing it again. Going back again next week so they can try something else with the relearn procedure. Hope the new trans works for you!
I have exactly the same problem described by you , they did the calibiration like 5 times and yet it disappears only for few weeks and then comming back again !
It is a delay engagement + hard / sudden jump when engaged .
Interest in knowing where did you reach with your dealer .

GM doesn't "remain silent" because there is nothing to say. If you are having an issue it is pretty clear they are willing to address it as long as you are working with a dealer capable of proper diagnosis.
"the service departments" are all part of independent franchises with their own employees that may or may not be proficient at working on certain models depending on their location, ability to use a computer (ha), or even who happens to be working or has a day off on the day you happen to bring your car in, they are not worker ants tied to the queen through magic esp. it's the same thing at the porsche dealer except there are a fraction of them vs chevy of course and information is probably disseminated more efficiently, although not perfect I am sure.

Sad as it is, this A8 issue has truly exposed another flaw within GM damn near as bad as the ignition switch debacle.

Recalls are for safety issues, like if your seat belt won't buckle or your wheel might fall off or your air bag might kill you, not for a weird shift in the morning.

Hell, just look at the way they handled the ignition switch issue or for that matter, the way the industry as a whole the air bag issue. They all suck. They get away with it because congress is in their back pocket.

For perspective, if it is people's safety you are worried about, what is the failure rate of medicine? Cold and flu medicine? Chemo? Herpes? How about condoms for aids or pregnancy? All NOT good and failure rates from 30% to 100%.....Compared to a newly designed complicated transmission with a year on the road with very good performance having an intermittent cold shift issue on a small number of vehicles I would say that you might want to refocus your consumer protection efforts to other industries where people are dying and it isn't because of their new Corvettes.
BTW, what problems are you having with your A8 transmission?

What do you want them to notify owners about exactly? Of all the publicity on this forum about the A8, there are 10s of thousands without issue. How many separate owners on CF have A8 trans or TC replacements? Even if it is 10, 20, 30 that is still almost nothing. We all know owners with issues go online to research more, cars, toasters, or shoes, doesn't matter.

Yep. Deal with it, reality is harsh and words hurt.
