They made a new Corvette. Make a new trans that works with it. Other makers have no problems offering 8 speed autos. Get with it, GM. Idiots.

So what 8 spd auto that anyone is making are you driving now? How's that working for you?:D

I seem to remember one of the car magazines discussing this. C7 engineers said there was no dual-disc paddle-shift transmission that could handle the 450 pounds of torque. The magazine writer said the Porsche PDK, designed jointly with ZF, could handle the torque but GM was not going to license parts from Porsche for the Corvette. Interestingly the Porsche 7 speed manual and Porsche PDK are almost the same transmission, many parts are the same. ZF designed it this way from the beginning to save production cost.

I think a new automatic will be introduced for a few reasons. Better EPA numbers, marketing, better performance via better hardware and advanced programing. Performance is my priority.

Automatic transmission computers are integrated into the advanced electronics in a modern car. This enables engineers to program shift patterns for economy and superior performance. The computer can sense what a car is doing via throttle opening, yaw sensors, traction control, abs, electronic differential, steering wheel angle sensors, brake pedal sensors, etc. Up-shifts, down-shifts, gear holding all are optimized. Though designs are different, auto-manual transmissions like the Porsche PDK and Mercedes AMG Speed-Shift MCT have advanced programing where the computer performs like a pro racer. The computer knows when to shift up / down, hold gears in turns, out of turns, under braking, etc. Shifts are faster.

We are not getting a PDK style, maybe one like the Benz? AMG Speed-Shift MCT is a traditional automatic design where the torque converter is replaced. This is a quote from Wikipedia: "Instead of a torque converter, it uses a compact wet startup clutch to launch the car from a stop, and also supports computer-controlled double de-clutching."

I'd be happy if GM has something that performs as well as the AMG Speed-Shift MCT. This is the transmission GM needs to benchmark if there is not a dual-disc option.

Maybe he drives a Chrysler. They offer cars with 8 speed automatic transmissions and you can buy a 300 for only $30,000.

But back to GM, from a GM press release...

"With Ohio Gov. John Kasich, U.S. Rep. Marcy Kaptur, D-Toledo, and Toledo Mayor Michael Bell in the audience, Akerson said GM will invest $204 million to retain about 250 jobs for an all-new, advanced 8-speed automatic transmission for future vehicles that offer customers improved fuel economy and outstanding performance."

If ever there was an appropriate screen name - you've got it.

Maybe...he could answer for himself.:D

Yeah, GM is working on a variety of auto trannys including collaborating 9 (front wheel drive) and 10 (hi-po) spds with Ford.

And that's a reply from a posting whore, that has made more posts in his 1 year of CF membership then I have in nearly 14 years.

If you posted based on direct question made to you, then your post count would be around a dozen.

Oh, I see...you decide to answer for someone else with an idiotic answer because I'm a post whore. :rofl::rofl::rofl:

I don't answer questions put to other people.

The DCT in the current M3 is a blast to drive!!! That was the most enjoyable part of driving that M3, besides getting pulled over by chicks that wanted to talk. A DCT in the C7 would be insane!

Yes, Net. Not only that, but 2012 was the third consecutive year that GM has been profitable.

"General Motors reported today a third consecutive year of profitability in 2012, with net earnings of $4.9 billion"

Was that before or after they paid back the taxpayer 100% of the money stole from them and handed over to GM.

Agreed! Puulease Tadge!! This is GM, not Yugo.
Make it handle the ouput and make it fit! You can do it Buddy.

Seems like very bad investment. 204M for a transmission. They could just send the C7 to ZF and Aisin and they have figured it out and sent the car back with a price tag for the transmission(or license). Of course if they got "free" government loan I understand the loose hand on the wallet.

The transmissions will used across the GM line, not just the Corvette. No different from the A4 in the C5 and the A6 in the C6. maybe 7,000 a year used in the C7 but 500,000+ a year in RWD cars and pickup trucks and RWD SUV's. Of course another version of the 8 speed will be used for FWD vehicles.

A C7 with a Dual Clutch tranny as quick as the one in the Ferrari 458 would be incredible.

Before I ordered my 05 C6 there were rumors of a 6 speed auto being released for 2006. I was assured by my dealer (a forum member) that the A6 wouldn't be out for 2 or 3 years and I should buy the 2005 so I bought one.
Burned once, I'll wait for a year or so this time and see when the new trans shows up. There's NO WAY GM can compete on the world market with an old school A6, no matter what the PR about torque numbers are. I guess MB and RR motors don't make big torque numbers so they need the 8 speeds? Come on GM, get real.

60ms shifts = sweetness.
It's a getrag, so if it didn't cost 20% of what it costs GM to build the entire corvette they would probably use it.

One of the engineers did say that they have gotten the shifts of the A6 down to 200ms. Thats ferrari 575m and f430 speed (and alot cheaper).

Jag F-Type with 495 HP and 460 lbs-ft of torque with an 8 speed auto.

Not sure but did Tadge actually say 450, or was the statement a generic "would not handle the torque"? Cause any C7 tranny is gonna have to handle alot more torque than 450 in the hipo models.
Maybe they are thinking 600-800lb/ft not 450.

I prefer manuals but since I'll use the C7 as a GT I'm delighted it has 7 speeds.
