Due to the leak of an SAE paper on a web page that conveniently no longer houses the paper, we now know a few things about the new 2015 Corvette Stingray.

Obviously, as the title of the thread states that the Corvette will get an 8-Speed automatic transmission. We know that because, (before the paper was deleted from the page) the summary stated that fact in plain English.

The torque capacity will hit the 1000 newton-meters (738 lb-ft) mark, and an overall ratio spread of 7.0. More ratios, the transmission, dubbed 8L90, means quicker off-the-line acceleration with a shorter first gear ratio enabled by the extra two cogs.

The new transmission could put the C7 automatic over the 30 mpg highway mark! What?!? That is incredible!

The full paper will be available for purchase in April 2014, but I think we have all that we need, thank you.

I wonder if they have any test mules out testing these new tranny's now? I would think so. This is a DCT automatic, right?

Disclaimer - all just my opinion...

It is not a DCT...it is a transmission optimized for more for MPG that sportiness....simply because you really can 't get much better A6 now for getting around a track

BMW has had 8 speed trannys for a few years now, and they are computer controlled. They shift A LOT as they are always trying to find the sweet spot for mpg. It gets a bit tedious on interstate when it's constantly shifting between 6-7-8....

No one should fear that they got screwed by buying the A6, and the A8 is night and day diff...it's not....and it's first year...like eLSD, I'm sure there will be updates...it took two updates from BMW in the first year to get theirs right....they had a huge dead spot off idle at first.

I'm glad they did it..it fits into my plans perfectly for a 2015 or 16 Vette after they dial it in...but for others who worry a lot, you did not get screwed with the A6....

Ditto what Glen said. This 8-speed automatic transmission might do wonders for big, heavy GM products, like large sedans, SUV's and pickups in the areas of performance and economy. Posted this following previously, but worth repeating to allay current 2014 A6 StingRay owners might have, as follows:

Note Tadge Juechter's statement (which he has made many times) since the January 13th Reveal, that GM computer modeled automatic transmissions with more than six speeds and that they do NOT increase either the StingRay's performance, nor fuel economy, but at some point (paraphrasing here) "that due to other car companies getting bragging rights about their eight speed auto trans, we might have to eventually do something just to keep up with their bragging rights."

I have a 2014 z51 on order with a dealer in southern California, it is at order status 1100 meaning GM has not accepted it yet, I was told by the dealer that I should get it in Feb 2014 but with the news of the 8 speed tranny for 2015 should I cancel my order and order a 2015 which I assume I would get earliest in August or September? any advice from you gurus would be appreciated?

read the posts above, no... I would not cancel for a transmission that will take MPG from 29.5 to 30.5 (my guess)

Not to mention that there might be teething problems to work out.

The current six speed StingRay automatic transmission is an improved version of the one in the C6. It has software upgrades, hardware upgrades, a new torque converter and is designed for much quicker launches. Tens and tens of parts were enhanced from the same name transmission in the C6 , and thus the StingRay's auto trans is much improved. These collective facts are why the StingRay's six speed automatic is faster, 0-60 than the StingRay's seven speed manual transmission.

No StingRay customer concerns or problems. In fact, StingRay customers really like their automatics and if that is what I had ordered, or were about to order, would not hesitate following through.
