Larry/car

Maybe it is my car? I left my son drive it (he has a manual Honda Civic) he immediately stalled it. Seems the clutch starts to take hold and "now" it is fully engaged. Higher rpm prior to actuating the clutch seems to overcome this sensitive clutch engagement. (I have not driven another manual C7)

Could be. I'm actually quite surprised how light and linear it is.

I found the shifter took a little while to get used to since it always wants to gravitate towards 4th. I also mixed up 3rd and 5th occasionally when I first got the car, but after a few days of driving it became fairly effortless and now I love it.

As for the clutch, not sure if it's just me but at first it took a little getting used to. From fully depressed, it feels like the first 80% of the clutch movement does absolutely nothing. It doesn't seem to grab at all until about 81% released. So at first it felt odd because I felt like I was jamming the clutch down 12 inches and then immediately releasing 10 inches of it before even bothering to give any gas.

With that said, again it's really easy to get used to so it's only troublesome for the first few starts.

Sidepiper, you don't have any issues now. That's great but have you actually removed the clutch cylinder and looked at the fluid? In a C6 manual trans the fluid was pretty much black after 1 drive and just got blacker and blacker as the dust continued to contaminate the fluid. So is your fluid clear or is it black also? Thanks, want to know before I commit to another manual trans.

I'm on my second flywheel/pressure/plate combination.

The first one shuddered/grabbed when releasing it slowly at low rpm (<1000) in 1st. The dealer agreed and it was all replaced.

The replacement is a little better but still does the same thing. So we checked crank end-throw which was well within limits...and actually on the low side of range.

I'm out of ideas and it beats the heck out of me. There are several other threads floating around where other owners have reported similar clutch issues.

Of course GM insists the shudder is "normal" and all the C7 M7's do it, but I've driven a couple of other Z51 M7's that are absolutely perfect. Its simply GM BS which the dealer is being forced to repeat to me.

There are 5000 miles on the new clutch now and every time I do an slow creep forward at a stop light I'm reminded of a Volkswagen I owned back in the 60's.

My 03 Z06's clutch was much better... both in pedal throw and engagement.

This is the worst clutch I've experienced in any performance car I have owned which include Porsche's, Ferrari's, Lotus's and DeTomaso's to name a few.

But aside from that... the car is awesome.

So I'll keep it and hope whatever is causing the problem comes apart while I'm still under warranty.

That has been exactly my experience. The last inch or two of clutch travel is where the action is, but once you get used to that it's a joy. Very predictable and controllable. I also have the same issue with the shifter. Getting to 5,6,7 requires some extra effort. But only 250 miles so far so things may change with use.

Mine makes a kind of click or snap noise if you release it too quickly. I can feel it also in the pedal. Not sure what it is but it's not pleasant.

Smooth as butter.

C7 clutch definitely has a different feel than my 04 Z06.
The Z06 clutch was smooth engagement, and C7 still has a little chatter when you let it out too slow, and it engages suddenly, not much transition.
Getting used to it now after about 3500 miles.

My clutch is very smooth. But, it does seem to grab all at once.
It took a couple of days to get used to it and I was fine.

It would be better if it grabbed over more travel.
The shifter is great. Over all, I'm very happy with it and I love the
hill assist.

Cheers,

I have 3000 miles on my C7. I can't complain about the clutch.It will do whatever I want it to do.If I want I can take off as smooth as any automatic.
If I want to launch,no problems.It works good for me.

I've heard the same thing. Doesn't engage until almost all the way out. Wonder if it's adjustable? (another thread?)

This is actually what i feared....

My sense is the Z51 has a taller gear and it cancels out this issue

An engineer here once said that the "level of tolerances and limits within Corvette components is so wide and the quality control at this price point so low" that you will have folks that have clutches that shift like butter and others that shudder horribly. Its just the combination of which part, assembler and how it was torqued/mated/seated that makes the difference.

I believe it.

Certain famous C6 issues: body gaps/peel, crackling/pop top, whining differential, harmonic balancer, seat rocking, squeaks/rattles are non-existent in my 20K mi C6 but others have from day 1.

Hey NYC, this is a 2014 Z51 with ARH long-tubes and a Halltech cold-air induction system.

And the crank end-play is on the very low side of the tolerance so that's not the problem as I had originally thought after the first R&R didn't help.

And we didn't just replace the clutch plate, we also replaced the flywheel and pressure plate. When the dealer first drove mine to check it out it was "a problem for sure". Now it's "GM normal" and I've yet to drive another Z51 with the same clutch shudder.

Also understand when you load the clutch with some power combined with a fairly quick release you don't get the shudder. Its only during the near idle rpm slow release 'creep forward' maneuver that you get it.

Go figure...

bjhayes

Same here...

Unfortunately the C7 has the same issue. The manual also says to do a complete fluid change every 2 years. The old Ranger method that so many people do is not the same as a complete fluid change and it is only a cosmetic fluid change.

ckwhite

Let me get this straight: you've forgotten which of your wife's Z06's has the short throw shifter (in which case she has more than one), or you've forgotten which wife, in which case you do(?)

SilverScorp

The MN7 is just ok. The C6 MN6 is better IMO. The 7 speed is overkill that basically has you searching for gears from 3-5 as it wants to go into 7 instead. Its also notchy as hell IMO as the shifter wants to kick out of gear into neutral when shifting. Other than that, its a great car!!

Dave@gotboostPerf

I hear ya, as mine has the dreaded shudder when taking off from a stop. If I'm ultra careful and really pay attention I sometimes can take off without much shudder but I've never driven a manual that you had to be so careful taking off unless there was something wrong. Like yours there has to be something wrong in the pressure plate, disc, throw-out bearing, flywheel area. Also like you I have owned and still own numerous cars that are manuals, and what I'm experiencing is not normal.
I'll be taking it to the dealer soon but after seeing the lack of joy with yours I'm not too confident they will be successful fixing it.

I find the dual disk clutch in the C7 is easier to modulate than the C6 but neither can be as easy to control or can they be slipped like a lower HP Honda. It reminds me of the Honda Accord my wife had some years ago. A magazine review called the standard shift transmission “switch like,” and it was. But manipulating the large gear clusters in the C7 will never make it “switch like!” Lots of HP and torque to control by the clutch and transmission.
