Got this note from my dealer today re. Z-06 order:
"I did find out production on the automatic will be 1-2 months behind the manual".
Confirm/deny/old news???

I have read another post that said the same thing. I don't know if this rumor has any true to it or not. Heck, there have been dozens of posts that the Stingray A8 has problems and will not be shipped when in reality it was a merely a quality control hold to verify that there are NOT problems with the A8!

They are working on cooling issues on the A8 on the Z06, don't know if it will delay things or not

I have a question. I'm sure they will eventually sort out the cooling issue but I'm sure there will also be some A8 that overheat and fail. That being said I have two friends (1 is really a friend of a friend) they both purchased used sports cars. 2011 911 turbo s and 2009 Nissan GTR. They both had massive trans failures and with no warranty were looking at something like 20k repair bills for the PDK and DCT. If the vettes A8 did break and wasn't covered under warranty for some reason does anyone know what the cost would be to have a new A8 installed? Just curious.

It's well known in the GT-R community that trans temps are an issue on-track. A few weeks ago I was at Roebling and a friend was running his CBA. After ~15 minutes he pitted in as his tranny temps were over 250*.
While a factory replacement GR6 would be ~$20k with R&R, I would be very surprised if a PDK suffered a major failure that only took $20k to resolve.
That being said...I am guessing since a built C6 gen 6L80 was ~$6k, a stock 8L90 would be $8k from GM not including the convertor.

I love manuals...

I know someone who had their Porsche 911 S PDK go in to limp mode on track after about fifteen minutes, mid 90's Texas day.

I'm thinking it might even be a little cheaper than that.
Back when I was drag racing my C6 almost twice a month, I remember pricing out a new 6L80 as I was readying myself for it to let go (it never did ) and a brand new stock one from GM was only like $2800.00 - $3200.00. The 8L90 could be as little as only $5k maybe? Plus labor of course. But either way, IT WILL cost less to replace/repair than a Nissan GTR's or Porsche Turbo S's transmission would be.

This statement is correct. I was told by one of the GM engineers while at the NCM, on Saturday, that they are indeed working on improving the cooling system for the A8, resulting in a delayed delivery.

This make daddy happy. What site did you use to price them out?

thegame

I wonder if they feel they cannot solve this problem what the chances are they just scrap the a8 for the z06 and go back to manual only.

Toilets

Only for the Z. My dealer has a A8 tiger shark gray stingray in their showroom as we speak. I was in there Saturday asking to test drive it while ordering my Z.

Snorman

Highly unlikely, but they are going to be tripping over the "track certified" claim for a long time.
The fact that they are already apparently struggling with trans temps is not encouraging.

You guys are amazing. The thread is about the A8 production being 1-2 months behind. There are posts about the Porsche as well as the GT-R replacement transmissions. Like who cares isn't this a Corvette Forum? Then someone post out of the blue that GM is going to scrap the A8 due to cooling issues. Where do these gossip issues come from? Just my perspective.

Stunt

The C7 Z51 A6 get hot/overheat as well at the track, right?

Historically, have there been any automatics that do not overheat when used on a track, Corvette or otherwise?

Nice any pic's?

Well....

Production is behind because GM is working on cooling issues. Fact.

Cooling issues leads one to question the replacement cost of an A8 if one fails out of warranty. Fact.

Comparisons are made to the Z06 competition (GT-R 911) Fact.

Approximate GT-R 911 costs are mentioned. Fact.

A6 Corvette transmission cost mentioned. Fact.

Within 1 month of the A8 hitting the streets a used A8 will be available on Ebay for less than retail. FACT.


At the moment A8 transmissions run from ~$1999 for a Hyundai A8 to ~$4500 for a Maserati ZF A8. There's a Cayman PDK listed for $9800 plus core.

Snorman

How about the fact that some of us have actually tracked our C7 A6's and the transmissions overheated after 10-12 minutes on-track?
Is that a good enough reason to discuss cooling issues relative to the A8, particularly in light of the fact that two members were at BGAP and told that there may be delays on the A8 because of cooling issues?

Possible cooling issues with the A8 were discussed from Day 1. This is not a perceived and subjective issue.

Why is it delayed 1-2 months? Obviously they are having issues that concern them enough to delay production. Yes this is corvette forum but it's also full of true car guys and not just brand loyal nutswingers. It would seem natural to bring up and compare to other high end cars that have also had issues with their auto trans. Hopefully z06 A8 owners will never have to fit the bill for a new A8 but I'm sure it's certainly possible so I see nothing wrong with comparing the replacement cost.

Also I never "posted out the blue that GM was scrapping the A8" I know this site has many members with excellent technical knowledge and merely inquired about the possibility. Take a chill pill kid

My friend is a dealer. All chevy stores received a letter mapping out Z06 production.
Manual coupes first. Automatic coups 1 month later. Automatic verts a month later and finally the manual verts last. That's what the letter stated. No reason given.
