Well, gosh... The super cars don't use manuals, why should we?

If you people want to keep bringing up the fact that super cars have DCTs, I'll bring up the fact that Smart cars have an AMT. Who cares what other cars have? We're talking about the Corvette here. If you can can give me a REAL reason based on YOUR use for the car, then I'd shut up about it. But I bet more than half of you know NOTHING about DCTs with paddle shifters let alone have driven one or even been in a car with one.

It's not that I'm against having the option for a DCT, because I'm not. I welcome it. But I just find it ridiculous how many of you guys are asking for it when I just know many of you guys are just asking for things that are found in exotics just because they're in the exotics.

To me the Corvette has always been an affordable sports car that can take it to the best of them on the track and leave on top with a quarter the money spent. There are going to be things about the vette that aren't as sophisticated or as luxurious as the more expensive sports cars but when it comes to performance the vette is king of the hill. It seems to me this is just another thing thats not necessary to spend the extra R&D on, I dont want to say a corvette is a budget car but it kind of is for the performance you get and I think the money would be spent better elsewhere.

Give me a manual transmission on a car with RWD and a strong motor and great suspension and I am happy, the rest are just frills that arent really needed.

And here's another example of the misunderstanding that the Corvette is competeing with "high end" mega priced super cars.
They have a 600+HP, 200MPH+, $110,000 super car that set one of the fastest 'ring laps for any production car. Like America in WWII, ready or not, with power like that, they're already in the mega priced super car fight.

As I just said a DCT is a manual transmission. It just doesn't have a clutch and you shift gears with the paddles Vs a stick in the console. All they are doing is moving the shift mechanism from the console back to the steering column where it was in the 40s and 50s. You just don't have to flop your left foot around on a clutch and can put it to better use left foot braking into a turn.

Europe has had a much higher take rate on manual transmissions for the last two decades. This recent trend towards DCTs is just that: a recent trend. Also, most lower-end autos purchased in Europe are still manuals. There is still a lot of demand for standard transmissions, regardless of what some would like to believe.

I don't understand how people still don't get this: some people enjoy clutching and moving a shifter. Pulling a paddle or pushing a button isn't enough involvement for these individuals, and I really don't see how it could be.

You know they build an evolution of the hydraulic automatic transmission that is direct drive. Also the current Corvette is directly coupled in most situations. Don't dis the torque converter, it is a torque multiplier, or didn't you know that? The torque converter could easily be removed and replaced with a clutch, and has been done by Mercedes, I believe. So it is direct coupled, planetary, electrohydraulically shifted transmission versus the ballyhooed direct coupled, helical, electromechnically shifted transmission DCT. They both shift faster than a human can on a consistent basis.

Before you dis planetary transmissions, they are plenty strong. I think you them in Super Stock drag racing, or at least they used. Those were in range of 1600 HP if I recall correctly. They used one lever per gear since that suits their purpose.

There are many ways to skin the gear shifting cat.

I want a gear shifting cat. A cat could shift much faster than I could -- the phrase is "cat-like reflexes" after all.

The Corvette's wide center console makes it well-suited for this technology. Just make a slight recess in the console immediately behind the shifter, give it a little padding (cats like soft surfaces) and trim it with alcantara (for better grip; you don't want your shifter shifting out of place under high cornering loads). Put a sock on the shift **** with a couple of feathers on the sides to engage sport mode for faster shifts. I don't know about skinning the cat, though; for a daily driver you want to maintain decent cold-weather performance.

GM simply must offer this technology in Corvette if it wishes to remain competitive.

I realize the industry loves to call them manuals, but I beg to differ. Any transmission that can shift itself is an automatic in my book. It may not have a torque converter, but it can still shift itself. Even when you "manually" shift it using the paddles, it is still a highly automated process involving lots of electronics to get it all done. There's no challenge to matching the revs, getting the gear selector in the right slot and so forth. I can't think of anything more totally boring. There is also a LOT more to go wrong, and the repairs when it does can be quite painful. Ask anyone that has ever had to have one of BMW's SMG transnissions serviced out of warranty.

I have no objections to them making DCT type transmissions available to those that don't mind being bored, but if I can't have a proper manual, I won't buy the car, period.

Although, if they don't offer a manual (which they certainly WILL offer one), I would look for alternatives that tickle my pickle. And if I didn't find a decent alternative, I'd still end up buying the Vette with the DCT.

However, I can't fathom driving an exciting car without a manual gear box.

Read the Vette Mar 2012 issue on the 2012 Auto transmission upgrade for faster shifts (65%) faster 1-2, 2-3, 3-4
GM has a patent on this new upgrade. It's a good read.

Mmmm. If you want a proper sequential transmission like the ones found in race cars in your street Vette, expect to pay $15 to $100 grand. There are a few driving around.

Pratt and Miller working in conjunction with Chevrolet have a pretty neat bolt on system that will give you pretty much what the Ferrari 458 has. You paddle shift and don't use the clutch peddle except for launch and stop.

A highly developed similar system is the most likely method that Chevy will use on the C7 gearbox. There will be two pedals on the floor in this case. Two electronically controlled electric motors will actuate pull/push rods for the under and over drive gear set shift forks. 4th will still be a solid coupling even with a 7 speed which will be in the over drive gear sets. There will be 3 under and 3 over. The clutch is fine as it is. Why doesn't corvette have a dual clutch??? I'll get to it later. Ferrari uses hydraulics to do this job which requires a full time pump located on the rear subframe next to the gearbox. There is no reason why Chevy can't make this electro mechanical linkaged gearbox automatic. You know when Chevy makes it, it will be built proof and refined. I have no faith in German engineering in this regard. No cars can be thrashed like Corvettes, period

Ferrari and Corvette GTE race cars use the X-Trac Xaxle and straight gearboxes respectively. Here is street version for your Vette by Emco.

http://imageshack.us/photo/my-images...6lgmotor.jpg/][/URL]

Unlike the production cars which use transmission that we are familiar with, these sequential units can't go from 4th to 2nd and 3th to 5th, etc. They have ratchet drum shifting mechanisms like motor cycles. They are lighter and stronger and can be shifted faster. The only reason F1 gearboxes are not smaller is because of the rules for materials and gear thickness. F1 car use dry carbon clutches. Sequential gearboxes are made by X-Trac, Hewland, Colotti, Getrag and Emco.

http://www.youtube.com/watch?v=tQErOpNCshA

These gearboxes make a lot of nice noises which most people don't like. Pre 93 ZF gearboxes used on Corvette 6 speeds had to be changed because the dumb f..s complained about the noise. The torque rating was revised downward as a result. DFs don't know the beautiful songs of the Muncie M21 and 22s.

Also, the seems to be a misunderstanding about dual clutch gearboxes. Instead of the Ferrari and Corvette systems described above, one clutch operates under gears and the other operates the over gears each on their own concentric input shaft. Both clutches are motor cycle type multi disc wet packs. They have oil pumping losses. Give me a locking torque converter any time for my comfort.
Porsche:
http://imageshack.us/photo/my-images...getriebe.png/][/URL]

There are many different designs ranging from epi cyclic(planetary) to splitter ratios found in class 8 truck Xmissions. Nothing is new. Italian and English armored vehicles had these type trannies in WWII.
BMW:
http://imageshack.us/photo/my-images...leclutch.gif/][/URL]

Borg Warner makes most of the hydraulic ECMs along with straight and Xaxle Xmissions. FIAT Powertrain Technologies makes DCT for Magnetti Morelli and Graziano and all these companies have joint ventures. They all have American stock holders.

I think you will find that DSGs in German cars are well developed and proven and can be thrased and shifts very fast. They have been around for a long time and Ive had 2 with them and never had any problems or loud noises and they shift insanly fast. This again is from a guy that had 2 German DSGs and now the vette auto. The vette auto doesnt even compare when it comes to how fast it shifts.

If you make such a 'wise' statement, Shirley you must be able to argue your points with some juicy tid bits of sound engineering solutions to back it up?

I guarantee I'll knock it to pieces on every count you make. You can start by listing your design objectives which must include cost. Compare that with what you already have and what you can improve.

A Porsche has a trans-axle, a Corvette does not. Begin your thesis now.

You are not one of those liberal types who want us to become Europeans, are you? Nah.

I'm not going to argue with you. I have been driving manuals for over 30 years. I love my 2008 C6 Z51 M6 with NPP ..I really do. And my c5 Z06 before this.

That said...I would prefer to purchase my next corvette with a Dual clutch or MCT transmission. I am sure if GM were to offer either of these transmissions they would still offer you a manual transmission so you can enjoy..

I have times were in my personal life as I use my corvette everyday in the Northeast where my life would be better with a dual clutch or MCT transmission.

I wouldn't attempt to argue with you but rather just let you know what I believe would be a better option..

That option would be to offer both types of transmissions so enthusiasts such as your self can still be tempted into buying a new corvette.

For me? I prefer the efficiency and consistency as well as the option of a full automatic mode when I am in situations that would make it more sensible. (for me)

Like I said...I don't use my car as a weekend toy. I use it everyday. Rain snow or shine. I use it when it suits me and I am of the type who prefers to enjoy the vehicles I own...

I've done the drag racing at englishtown...I've done the road course driver events at pocono...I've done decades of autox...I also drive into manhattan ..

for a person like myself and I feel there are many corvette owners like me....the DSG or the MCT (amg) transmission in the next corvette would make for a wonderful enticing option..

Porsche acceleration seems to prove the point..the pDK chrono versions are faster than the manual version.. in all acceleration tests..

Thats just a fact..

Have a nice evening and please know I respect your choice for a manual transmission if thats what you desire.

Please consider offering me the same courtesy with regards of a preference for a DSG or MCT in a corvette..

Its better than argueing...point counter point...

Happy holidays

If the C7 is offered with a DCT, that may be the route I go. Otherwise, I'm sticking with a standard. I don't like regular automatics at all.

I took a ride in a smart car as well, and that has to be the worst transmission I've ever had the unfortunate experience with. It almost makes you sea-sick. That's not a win for the automatic manuals. But as long as there's a fully automatic mode in with a DCT in the Corvette, I'd be happy with it.

It looks like I may be taking a new job that requires me to actually leave my house and battle LA traffic every morning. So this would be the time I feel an auto is a good thing for me. I've driven manuals for so long since I've always worked from home, but the times I have to deal with Los Angeles traffic are the times I just want to kill myself.

I love the 7 speed automatic in our Mercedes SLK55 AMG.

I think GM should take a look at Mercedes transmissions to figure out how to make a proper Automatic.

The smart car had a single clutch and was a horrible car overall..The new 911 has the dual clutch technology that leads the way. Same with ferrari and its rumored the Audi R8 will dump the old tech single clutch and go for a dual clutch soon..

This technology is leading the drivers revolution. I think corvette should offer this yet with GM being the largest manufacturer of the worlds best torque convertor automatics...I tend to think GM will be late to the party.

I'd be pleasantly surprised to see either DCT or MCT in the first year C7...maybe down the road for the C7 but probably C8 will be the model to recieve dual clutch technology.

GM tends to look at empirical data and the true benefit of DCT is more along the lines of direct feel that places it above a torque convertor automatic..

I say if its good enough for ferrari, porsche, BMW, Audi, bugatti and the list goes on...

Its time for GM to step up to the plate with this technology for corvette.

I'm not quite sure the tech would transfer to the truck lineup which many of what corvette benefits are to the corporation is about...so we've got a bit of a wait for the DCT or so its been rumored..
