Ggarnier: Here's a follow-up to my comment above. GM's answer to your question about how the 8-speed will be used: "We have not yet announced what products will get the 8-speed, Toledo-built transmission."
GM's eight-speed transmissions are being developed for production vehicles, Ggarnier. The company invested $204 million in the Toledo plant where they're being built. As of now, I don't believe GM has said which vehicles will use the eight-speed, and when they will appear (we've e-mailed GM to double-check for you). Reports from various news organizations have speculated that the eight-speeds will be used full-sized pickups and SUVs, with possible launch in early 2013. My guess is we'll hear more about it at the Detroit Auto Show in January.
I hear that the Ford CV transmission was dropped because of business concerns. The transmission was expensive, it couldn't handle the torque of the newer engine that was planned, and people didn't like the way it behaved. Drivers are used to a certain cadence of sounds and the CV doesn't produce the same sound and feel that people were comfortable with.
Just the same, I'm sure the top reason was the cost compared to the six-speed.
Just about every hybrid being produced today has a CVT along with cars from Audi, Suburu, Nissan, and Mitsuibishi, to name a few more. One plus for the CVT in slightly better fuel economy than with a "normal" automatic.
"GM has been building eight-speed automatic transmissions at its assembly plant in Toldeo, Ohio, but none of those transmissions are yet offered in current vehicles."
Is this pilot production for development and test purposes? If not, where are these transmissions going?
@TJ: Still think it's necessary since there is no way there will be a singular shift to pure electric even with stable and formidible battery technology. There definitely still needs to be choice and this type of intra-industry sharing of R&D makes perfect sense in terms of bettering the choices.

A higher speed count means better mileage - ok, I save some money on gas. What other cost ramifications will impact us? How much more will the transmissions cost - how much will they add to the sticker price?
How much more likely will they be to fail, and what cost to repair?
If we can get to all-electric vehicles (darn battery storage!) then this wouldn't be necessary; variable frequency drives give the infinitely adjustable speed control.
You're right, Chuck, there is a long history of automakers sharing technology developments. Automakers also share lobbying efforts. While it may seem odd -- or collusive -- for competitors to share development, well, they are under some heavy pressure to deliver the CAFE standards they're facing. I would imagine the government would be supportive of this type of sharing, since it is directly related to heavy government demands.
For 3D printing to make the jump from rapid prototyping to manufacturing, engineers will need to find easier ways to move products from their CAD screens to their printers.
Gigabit and PoE are two networking technologies moving ahead in tandem as industrial users power remote Ethernet devices such as IP security cameras at 1,000 Mbps over existing CAT5 cable.
New versions of BASF's Ecovio line are both compostable and designed for either injection molding or thermoforming. These combinations are becoming more common for the single-use bioplastics used in food service and food packaging applications, but are still not widely available.

For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
