Im hearing the C8 will only be offered in automatic......How true is this? I'm guessing it will be more accepted if its only paddle shifters...
Not like the present auto set up where you see the shift column of P R N D.......To me there is def something wrong when I see a Z06 or a ZR1 and you see P R N D.......Sacrilege......That's just me....

It's been a thing of the past for the last 15 years or so, just like the ICE will be a thing of the past in another 15 years. Technology progresses, some people don't want to, and that's fine.

Its got to be DCT for me to consider it, I'm ready. The Porsche GT3 brought back the manual so there is a slight chance someday it might have one. probably .1% ha

A DCT is not an automatic as people generally use the term.

An automatic transmission has a fluid clutch (converter) sometimes with a lockup clutch on the converter. The rotation of the outer converter ring (turbine) causes fluid to circulate and drive the inner ring (turbine), allowing for slippage without wear.

A DCT has 2 clutch packs, one driving the even gears, the other driving the odd gears, these clutch packs contain friction plates and drive plates; pretty much like manual clutches.

I could Google....What does DCT stand for ? Dual clutch? From what I hear the C7Z has a lag between shifts when you use the paddle shifters....C7Z C7ZR-1, manual all the way for me.....

I'm just guessing that the C-8 will be automatic only.....That way, you have no choice....

Anyone ever drive a lambo or a Ferrari with paddle shifters? Im guessing the shifts are lightning fast...

A DCT is an automatic as automobile manufacturers use the term. Look at their websites.

The Lambo's Dual Clutch Transmission is lightning fast. In the time it takes me to move the shifter in my C5 from first to second (not counting clutch time) The Lambo's DCT has executed the complete shift.

Humans driving new cars will be a thing of the past in probably less than 10 years. They should offer a manual so we can enjoy the entire driving experience, while driving is still around.

VW/Audi/Lamborghini have been at the forefront of DCT technology for years now. I happen to have a 2018 VW Golf R with close to 300 HP and a DCT (my first). It's pretty nice and I have nothing but praise for the way it works.

It has auto and manual modes as well as eco and sport modes. So you can pretty much drive it any way you want.

The test cars I have listened to carefully all have DCT transmissions, without doubt.

100% correct.

Wrong. "People" generally use the term "automatic" to mean a transmission that does not have a clutch PEDAL and does not REQUIRE the driver to manually switch gears utilizing said clutch PEDAL. The fact that a DCT has "clutch packs" and other internal parts or the fact that the "C" in DCT stands for "clutch" does not matter even a little bit. It's irrelevant to any but the most pedantic. If it has a "PRND" shifter, it's an automatic, paddles notwithstanding. I'm cool with the fact that the next Corvette will have a DCT, but let's not pretend it is any way a manual transmission. That is completely misleading.

Bikerjulio

The problem with the discussion is the amount of emotion, hatred and bias against the word "automatic".

The term has become associated with inefficient slushboxes of yore.

We just need a new term that means that the transmission can shift automatically if desired, or manually too.

VW use "DSG" for Direct shift gearbox.

Racer X

The current generation 8 and 10 speed torque converter transmissions can shift automatically and manually as well.

mschuyler

Using this creative "new" definition of what constitutes a "manual" transmission my old 1964 Dodge Dart qualifies as a "manual." It had the shifter on the dash and in addition to "D" it had '1-2-3" buttons. I could (if I wanted) push "1" "2" and "3" to "manually" shift through the gears the same way you can pull a small lever near the steering wheel to "shift." See? Manual Transmission! How innovative! I see the light now. Thanks.

Well, duh.

I own a 458 and the 7 speed Getrag DCT is the best all around transmission I have ever driven.

Smooth shift in auto mode and lighting fast up shift and down shift in manual mode.

I have heard so many guys on this forum insist on driving a manual transmission. All I can say is spend 1 day driving a high performance car with a proper DCT like the 458 or Hurican and you be sold.

DCT give you complete control just like a manual but snaps of shift that are brilliantly quick. Really a fun driving experience .

I also own a Callaway sc757 with the A8 and the delay while in manual mode is very apperant. While it will shift quickly the fastest shift only happen in auto mode with the throttle hammered down and then transmission will kick into performance mode.

Really a shame GM did not offer a on and off option to put car in performance mode A8 .

NY09C6

It doesn't matter how fast it shifts. A DCT does not provide the experience that the manual trans does. I have driven them. If this doesn't make sense to you, you probably did not really enjoy driving a manual. For me a DCT is boring,

Btw... I have no doubt that a DCT would be faster around a road course for an average driver.

For any driver!

I think you may have missed my point about the DCT.

I have driven many manuals and my 2015 Z06 was what I traded in on my 2016 SC757.

I guess for my what makes a manual transmission fun is the mental thought process and the freedom to precisely chose which gear and exactly when you want the car to shift and the reaction of the car to that gear change . These experiences are all there with a DCT just happen much faster than any driver no matter how good or experienced in driving a manual could ever hope to achieve.

The closest the C7 can come to that is when your performing no lift shift.
​​​​​​
Even then there still a power interruption in that moment it require to engage and disengage the clutch.

I never found in all my year of driving a manual that the enjoyment came from pressing a clutch peddle or king the gear lever. For me the enjoyment was the precise control.

I never had anyone who is a car guy drive or ride in my 15 458 that did not comment on how unbelievable the shift speeds are and get a Hugh smile in snapping off lighten fast shift with absolutely no interruption of the power delivery.

Again if you DCT experience was in a VW or Cayman or similarly low power car I could completely understand why you may be underwhelmed by the experience .


If you a car guy and most likely you are as your on this forum all I can say is if you have not driven a late model Ferrari or late model Lamborghini that have power level similar to a Corvette but with a DCT you really owe it to yourself to drive one and do so while driving it as you would when hustling trough manual gear changes at a rapid pace I bet you would not be board but find the experience truly a blast.

I sure everyone would agree driving a manual in slow stop and go traffic is not exciting or fun. Really the fun comes when your hustling the car and setting up for cornering or coming off the line that is the fun part of a manual transmission as you have control of exactly what you want the car to do.

With a Great set up DCT you have all the same control and can make those changes in dynamics happen at a faster pace than any driver ever could in a manual.

But for those that truly enjoy the pysical aspect of pushing a clutch or moving a gear lever I suppose that you must be having a real blast in stop and go traffic shifting from 1st to 2nd to 1st to 2nd to 1st to 2nd. Now that to me is utterly boaring.

The lack of DCT is the only thing holding back the C7 from being a world class driving experience.

I say that and that from a Corvette loyalist on Corvette number 11 and excited to have a space in my garage to add the upcoming C8.

I hope GM offer 3 things 550 plus horse power and a HTC roof and a DCT trans. I have no doubt the car will be packed with the latest and greatest tech and in true GM fashion will be absolutely gorgeous to look at and a blast to drive.
