C8 transmission DCT change?

[TNBlueVette]

I was just wondering if the "rumor" that I came across on another "forum" had any legitimacy to it with anyone in the know here about a change to a different transmission or not?

Nobodyknows anything for sure yet I d suggest we should most likely see a dct in the standard c8 and upper models as they become available.

fords gt500 coming with a dct pretty much shows the torque capability withthe newly engineered dcts ..

no reason to expect that the c8 wouldnt also come with a dct.

the time has come for american performance to accept the intrinsic value of the dct...

full on track performance of the A10 Im sure is amazing as in the camaro ZL1 1LE the A10 is actually quicker then the m6.

the part throttle street driving 6 or 7 tenths with the torque convertor automatics seem to be slightly lacking compared to the direct connection “feel” and thats where the dct excels.....in driver feel being connected.

hope that helps

Let’s all take a big time out on giving any credibility on a rumor coming from another place, and then our getting once ounce upset about that info prior to it being confirmed, for that other internet location was/is the place that started the “ME starts at $169,000” price and also the source, “that it is confirmed that the ME will be revealed at NAIAS.”

Let’s take JB’s caution in hand and proceed from that perspective. We know nothing yet.

I think this hits the nail on the head. I own a M7 but rented an auto a couple times in Cali and ran canyons with it. In performance mode the trans was actually pretty good when really pushing it-good up and down shifts and held rpms in the sweet spot- but when backed off a bit to it just felt slushy. There are times on the road that perhaps you don’t want to buzz at 5k rpm to the next turn 1/2 mile down the road but still want crisp response. I imagine it is really a programming thing but I still won’t buy a tc vette so I REALLY hope the dct gets good programming. I also hope the c8 gets a torquey motor-I actually prefer that to higher rev all the power up top motors.

GM, give me a low end TQ motor and manual and let do my own magic and not a computer shift for me. I've always loved Corvette for low end power and manual tranny.
They can offer DCT for the track version, but at least give us manual for one of the versions.
Ford is already considering ofering Manual on GT500.

I was stunned that corvette interior spy shot does not lend itself to a manual transmission ..

with 22 percent of all c7 s were sold with manual transmissions as thats a really high number considering most corvettes sold are ordered by dealerships..for inventory...

the dealers feel they can sell an automatic to anyone but the manuals are a tougher sale with a much smaller customer base these days..

i would have thought the base standard c8 would be a manual transmission and as usual the automatic or in c8 case the dct would be an upcharge.

that would have allowed a lower msrp for the magazines to go on and on about how great a value of the corvette is all the while selling nearly 80 percent with the upcharge.

i would have though worst case scenerio..,,the standard transmission would have been a manual transmission and just not make it available at the start if production forcing the dct upcharge to clamoring public. When sales started to slow down...the manual would be a high demand feature and in demand..(second year)

Sadly many have said the photos of the c8 interior show that no manual will be offered because the interior cant support a manual transmission?

after owning manual transmission sports cars for over 40 years...im ok with moving to a dct transmission and i would have ordered one anyway..this time around...

supposedly the dct is so cool all ferraris , lambos and mclarens are now dct s...so I figured Id give the dct a shot this time around.

maybe the manual transmission feauture will make an appearance at some time during the c8 lifetime to meet manual transmission enthusiasts..

otherwise camaro ZL1 or SS will become GMs manual performance options for purchase...

i expect the camaro will shift to a seventh gen restyle pretty quickly after the corvette goes rear mid engine

The whole car was designed with DCT in mind. It’s time to build a ME Corvette with DCT like all the true exotic super cars. Want to compete with the big guys, that’s what it takes. The trans is a known quantity.

In Manual, I never abused the clutch with hard take offs or drag racing, so I've never burnt clutches, of course all my clutches were replaced by performance clutch shortly of the car was bought, because factory clutches are worthless

Then the question comes, if we go with DCT with it's internal clutch builtin, how often do we have to replace clutch? How expensive is to change DCT clutch. A guy who own one of the Lambos with DCT gen 1, he said, he had to have the DCt clutch replaced every 10,000 miles.

I think the Corvette is one of the few sportscars that people want a stick. So if that’s the case offer both until sales prove outhewise. Sales figures will tell the need or not.

There are a couple of essential differences between the use that DCT clutches see and that in a standard MT car:

1. There is minimal slipping of the clutches in a DCT.

2. In normal operation next gear is already fully engaged before the shift happens. Then the engine is perfectly rev-matched to minimise shock to the components as the matching clutch is operated.

I'm also on a Golf R forum. The R is an interesting example because the same car is available with either a MT or DCT transmission. The forum is full of complaints about the stock clutch on the MT car. Not a whisper of complaint about the reliability of the DCT. Mechanically it appears to be extremely durable. Not only that but these cars are commonly modded for more power, and it seems there has to be a very substantial increase before problems occur. Like 2 times stock.

I remember visiting the Lambo dealership in Marysville Ohio years ago (don't know if that dealership is even still there), and finding out that a Diablo clutch job was about $14,000. I think they call that up-charge the Lambo Premium.

Also, that was not a DCT.

Wthe early italian exotics were insanely unorganized for proper service.

gm has warranty cost constraints so that gm designs maintaince and repair costs to be much more managable...

the early computerized clutches later on before the huracan were single clutch computer controlled...

the single clutch even with bmw or ferrari were brutal from a maintaince and repair perspective.

dual clutches are much more managable and reliable....service intervals are as well...

What is the/their source of this?

If true, would assume it would be all over the net, like the electrical issue...

[John]

No source was given. No details other than the very intersting comment that the ME was consequently going to have the same trans as the C7’s. But even that was incomplete for it did not specify whether that meant only the A8 or the A8 and the 7M.

after hearing today that they can't get a DCT that works they are going with the C7 transmission I'm out unless something changes...

Nothing more than an unsubstantiated comment IMO at this point in time.

I hope no one is getting more needless angst as we did re some many previous comments, some completely already discredited by time, others by their insanity (e.g., the C8 is going to start at $169,000). And then so many others ones, e.g., such as the Corvette will be its own brand (which we saw 100% disproved ten days ago by the “Corvette by Chevrolet” leaked IP animation start-up video), etc.

Rumors come and go; let’s instead sleep well tonight knowing that when the ME is revealed, it will work very well, drive extremely well, and have great looks.

I'd prefer a manual, too. I know all the data says the DCT shifts faster, gives better performance, etc., etc. But I'm not racing my car, I'm driving it on the street. And to me, the .1 second gained in 0 - 60 doesn't matter at all, and driving a manual is just more involving and more fun for me.

That said, it appears there is zero chance of the C8 coming with a true manual. At least the DCT is more involving than a slushbox auto.
