Sequential Transmission
While watching Le Mans today on the Speed Channel they had an in car camera in one of the Corvettes. The most noticeable feature was the truly sequential transmission. These type of transmissions have been around a long time in racing and now are in some cars like BMW's as an option. How many people would like to see such a transmission in a C6/C7 and how much would you be willing to pay for it?
Please note this transmission is not an automatic with a manual shift valve body and torque converter.

That, IMHO, is the primary reason you don't see this type of transmission in street cars.

I feel the best tranny unit out there bar none is the Audi DSG (Direct Shift Gearbox)...makes the SMGs feel archaic in comparison AND the DSG is already being fitted to the high out put engines Audi makes...I am a gear clanker from WAY back and love shifting but if the Corvette had a DSG option I would select that without hesitation...

I recall seeing a thread someplace about GM patents for a planetary transmission without a torque converter. Instead it used a friction clutch and internal clutch packs for gear to gear changes.

I have an M3 with the SMG and I am not impressed at all. For one thing, there are too many shifting "modes". Another thing it that the car shifts kinda lazy up or down. I can shift down, and sometimes the car gets "confused" and doesnt shift when I tell it to, thus sometimes making me go into certain points in curves in the wrong gear/RPM. I just dont like it at all.
Driving the SMG M3 gets boring. I used to have an automatic in another car that I manually shifted and to be honest that shifted faster than the M3 SMG system.
imo, I simply enjoy shifting a pure manual too much.
I realize that the F1 guys use the sequential due to the fact that its fractions of seconds faster than manual shifting, and I am sure that is important while racing for real money. So, in a streetable Vette, there is no way that anyone will relatively notice that fraction. If you think that you do, then you are kidding yourself.

Shifting is fun, and that will soon be the only reason to have or use it. These new fangled auto trannies will eliminate 'performance' as a reason to manually shift.
