Eight-speed Automatic transmission

Luckily the hillclimb manuals state differntly p37
"10.35. AUTOMATIC TRANSMISSIONS AND HAND CONTROLS
Allowed for Time Trials."
manuals are fun, but when going flat out give me sequentially operated gearbox (even if it has a torque converter
attached to it). Left foot braking and no missed shifts

Hello everyone. I'm new here and I wanted to introduce myself.
GM's news 8 speed is an exciting topic and it is a critical advancement in my opinion for many GM products to come, including performance vehicles, trucks and luxury vehicles.
The new 8 speed will first be introduced either with (if everything goes as planned) or shortly after the introduction of the 3rd gen Cadillac CTS and C7.
GM still plans to offer a manual with the C7 for those that want it, but it goes without saying that it simply won't be able to match the performance benefits that an 8 speed will provide.

Let me begin the process by a couple of quick questions: is this new 8 speed a ZF - similar to F type Jag or is it in house GM ? DCT or conventional ? Will the C7 have it available immediately?

By the way, I would never debate the engagement or fun aspect of an auto vs manual because that is subjective and in the eyes of the beholder so I won't be waking that baby
, however, the new 8 speed will certainly be a huge advancement for the C7.With that said, there isn't a lot of information on the 8 speed at this point, but there are going to be two kinds of 8 speeds that GM will use. One will be the Aisin 8 speed that will be used for for some applications, but GM is also working on a home grown 8 speed as well for other applications. Which kind will apply to the C7 hasn't been confirmed, but I'm sure the Aisin 8 speed will be used for high torque and performance applications like the C7.
Based on the Aisin's characteristics, which include smooth shifts, low unit weight, and high torque capacity, I think it should be a great auto.
If things go as planned for the C7, and I don't see why they shouldn't considering the tranny is going to be sourced by Aisin, it should arrive at launch.

I have to admit that, as a life-long stick-shift lover, it saddens me to see the manual becoming less popular. That said, I'm having to deal with a really bum left knee and having to shift in traffic is getting painfully old. I applaud the move to newer, more dynamic transmissions like DCT for the masses like myself. Maybe by the time I can afford my C7, there will be a really fast, solid, automatic or DCT that will have NO compromises.

Manuals/DCTs experience fluid shear and overheating on the road course too, that's why they make coolers for them. There are bigger coolers made for autos to aleviate any overheating issues. In addition, since a DCT uses hydraulics to apply and release the two clutches, they require a pump just like autos which eats into their efficiency too. If they allowed autos in road racing, they would dominate because of the computer controls...you can't beat the computer. It's the same reason they don't allow ABS or traction control...the computer is doing the job. BTW, autos do dominate on the drag strip so just cruise on by with your manual while the performance guys hash it out with their lowly autos. 
I'm not against DCTs, I just have a more open mind. I personally think a DCT could replace the auto and manual in the Corvette so GM only has to deal with one single transmission which would lower costs. It'll make the auto guy happy as well as the manual guy...win-win.

The function of a sports car for me is hauling ***. imo anyone who buys one for any other reason is strengthening the negative stereotypes of those who buy these cars.

Then why make Convertibles? Why make base models? GM should just make a ZR1 variant only. Why not turn the Corvette into a $150-200k race car only?
You are clueless when it comes to the purpose, market, and history for the Corvette. As well as the purpose for Sports Cars in general.

engineering and functionality will always give way to the wants/ needs of those who want to dilute the function of the cars.

I don't care about how fast the car goes as long as I have fun driving it. DCTs are for people who want to go fast around a track. Manuals are for people who want to have more control over the car to have fun with.
We all know a DCT can shift faster and more accurately than a human. But when you take the human variable out of the equation, you lose the purpose of having a "fun" car. Might as well just go to an amusement park and ride rollercoasters all day.
I like to control my car and I like to shift. If I ever see the track, it won't be often so I'm sure that driving a stick isn't going to hurt my times much anyway. (Not like my times will really matter at that point.)

Hence why most of my cars over the past 10 years, have been RWD and manual transmission.
