20,000+ Z06s out there - 80% A8s. Do you know how many failed out of that number? All of a sudden you see the % failure rate is very very low. This is something that happens everyday for every car manufacture out there. When dealing with 1000s of moving parts there will always be a failure rate and all manufactures know this. The difference is when you see a bunch of members have issues on a forum it seems like a massive deal as if all A8s are doomed or unreliable which is total BS because 1000s would be failing not 100 or less out of 16,000 or more Z06 A8s. Sucks for the OP but **** happens and why there's a warranty to get a new trans.

We have good news and bad news and let get the good news out first:

1. I am getting a brand new A8 transmission and torque converter from GM (this is what I wanted) I heard back from the master vette tech at my dealerhip this early evening.

2. Bad news, my Trans was was "Burnt up and my tranny fluid was smoked" per my dealer. He went on to day that a very small percentage of the A8 trannys have a problem with the Valve Bodys and apparently I was one of the few unlucky ones (but this means brand new trans. which is good news from my perspective). He also went on to state that it is "unusual for the tranny to be cooked when it has a bad valve body so there may have been another going on with my fried trans but good news I am getting a brand new tranny and t. converter."

Will know in the next few days when the new trans. and torque converter will arrive.

Questions:

1. They have to flush all my tranny lines to do this swap properly?

2. What else most be done by my dealer to make sure the tranny swap is done 100% properly other than not scratch, ding or knick my baby?

Thanks.

Congratulations. Just wondering...has GM announced any changes in the A8 replacements, or are they sending out the exact same transmission that has been failing?

Don't know, probably same trans. that has a small failure rate would be my educated guess.

Great news make sure you mention about flushing contaminates out from the cooler lines and quite honestly they should be changing the cooler.

don't say it to insult say it as a matter of concern.

"is it true that if the lines arent flushed out properly it could cause harm to the new components? and are they changing the cooler out? won't the contaminates from old trans be stuck in that cooler?"

^^^^^^^^^^ important

let us know what's said to you.

I do like the launch mode and I do love the car. would like a more durable trans.

I bet it is the tranny also, I have had a 2012 and 2014 Silverado with similar sounding problems and both times it was the tranny. They told me the reason it would get to where it wouldn't move me at all was the filter would fill up with tranny pieces and then when I turned it off asnd let it sit for 5-10 minutes it would fall off the filter and run fine for a bit then back to no driving. let us know what they find

You had no issues with the trans prior to failure? Was there ever any indications, temps, hesitation , smells etc...
Sorry if you already addressed this...

First post covers most of this in detail.

Regarding what was not covered tranny temps were always on the low side which I understand is normal and there was not bad or strange smells and no bad mechanical sounds.

"% failure rate is very low"...You mean like the valve guide failure in the previous gen's? That was very real...where many had the same response as you did in your post...and yet, there is now a class action suit over it as well.

Numbers dont lie... do they. 87 failures out of 16,000 A8 Z06s. 0.5% failure rate.

Btw if all 87 people wanted to file a suit over being put out because of the failures they could do so. Does that make a difference? You dont need many to file a class action...

If 0.5% failure rate for mass produced automotive drivetrains meant (junk and unreliable) then the entire car industry would be in a world of hurt.

Manufactures understand that there are going to be failures that come back when making drivetrains with 1000s of moving parts. Doesnt matter if its a Porsche or a Corvette. The PDK trans for Porsche is arguably the best there is, but yet I can send you a load of failed PDKs posts from pissed off owners on the forums that cant believe it because its Porsche. Should we call the PDK crap too? Not at all.

It blows when it happens to you, but thats what warranties are for and even the OP accepts that its a tiny failure rate, is getting a new trans under warranty and moving on.

While having to get a new transmission sucks, at least you are getting a new transmission!

I bought a 1995 Corvette 6-speed manual brand new and had to have the transmission replaced at 1,400 miles. It happens but is only an inconvenience. The replacement worked great and lived a long and happy life. Hopefully yours will as well and it'll be a one-time occurrence.

All things considered, that's great news, Jimmy. I think the inquiry about flushing lines/cooler is a good one to pursue.

Hopefully you won't have to wait long for the new trans. Would be great to get buttoned back up and back on the road.
