Since C8 models don't exist yet, I assume you mean C5 based on your listed type pf vette you own. I'm guessing a C5 clutch replacement will probably push around $2K at a dealer.

one more in a nearly endless list of reasons anyone purchasing a new corvette
or even thinking about purchasing a new corvette,
needs to buy a matching set of shop manuals and own a garage with a lift.

personally I've never understood the reluctance of most people to learn the skills or acquire the tools and reference materials required to do their own work on their corvette, vs handing buckets of cash to what in many cases is someone working for a dealership that is learning their skills on your new car!

nope I mean C8...I think the costs will be crazy for a lousy clutch replacement....what else is new ?? u gotta pay to play....large!!!
I think that's the big question everyone is waiting to find out... how much is the C8 going to cost. I've seen arguments to support either way (affordable/out-of-reach). Everybody wants to know. I personally believe it's going to get more expensive.

Stay tuned in. :cheers:

As earlier pointed out, since the C8 is not out yet we can only guess at the answer to your question.

First, the most constant rumor regarding the transmission has been that the C8 will use a version of the new Tremec Dual Clutch transmission (Link Below). There is no mention of clutch life expectancy on this trannie, but it does say that the shifting will be controlled by an electronic module programmed by the car manufacturer. Therefore, there will be no riding the clutch. No burning due to hill starts. In short, no left foot abuse of any kind. I will miss that left pedal, but like so many other things in my life, technology can control the clutch better and faster than I can.

Second, the cost of a current rear trans clutch replacement (C5, C6, & C7) is somewhere around $2k (Anyone with current info on this, please jump in here). We have seen the CAD drawings of the transaxle and engine APPEAR TO show the tranny as being accessable from the top of the engine bay. Again, this is a guess based only on the CAD pics that do NOT show a view of the engine bay. Until we see it we cannot be certain, but it IS possible that it could be less expensive for labor due to possible easier access. Parts costs? Maybe Tremec could tell us.


Third, the C8 is being engineered by GM, not Ferrari not Lambo. Economic serviceability is a much higher requirement at GM than at Lambo or Ferrari. That said, GM's record is not perfect, but the C8 should have a bigger engineering budget than ...say, Fiero. Questions like yours will certainly bombard the Corvette Engineering staff at every Corvette Meet/Show they attend - if not asked by Automotive Journalists. If they avoid the question or drop a huge $$$ cost, it will negatively impact sales and GM knows this.

GM knows that FAR MORE than any other GM car, Corvette enthusiasts dig into the engineering of our icon and are not bashful about giving thumbs down on everything from a color to too much weight in the car. So make a long list of questions like this and let's get it posted here and warn Corvette Engineering that we will want answers to some $$$ Questions regarding maintenance.

By the way, notice that the trans/axle in the CAD drawings has very little overhang behind the rear axle, unlike the most traditional transaxles. Here is a ZF transaxle:


When compared to the CAD drawing above, it is obvious the C8 COULD have much more, deeper space for storage behind the engine compartment, or the car COULD be much shorter than other Rear Mid Engine cars that use a ZF=type arrangement.


Below is a pic where you can see that the rear cammo is not real thick - see fascia body cammo above the exhaust. Now look at the CAD and make note of the shape of that transaxle, the angle of the exhausts, and the distance from the centerline of the rear axle to the back of the overhang. Now look at the spy pick below and imagine a removable trunk liner made of carbon fiber / composite / whatever that is coated with a ceramic insulator like Lizzard Skin to keep the heat down to an acceptable level. With the exhausts placed extremely outer edges, the width and depth of this irregularly shaped storage would seem to be pretty sizable, IMO.

Yep, remember the Monza V8. You had to pull the engine (almost) to change the plugs. Hopefully that engineer has been fired or he died of old age. I would never wish death to someone but I have been known to smile at certain obituaries.

Your a retired EE.
Engineers usually don't trash each other.
That is a mechanic' s job.

Alot At at stake with that C8.
Skeptical myself.

Only Version I care about is the Flagship Turbo Turbo.
$150 K for sure to own it.

The Monza was built on the Vega Platform. It was never intended to have a V8 in it, but yeah, they did that.

BTW, the Monza design was heavily inspired by the 2 rotor and the 4 rotor mid-engine Corvette concepts.

The Engine & Transmission will have to be dropped out as a complete unit bolted to the Aluminum Cradle shown in the CAD Drawings.
Really not much different than a Modern Minivan FWD or AWD Layout.
I have dropped the engines & transmissions out of Chrysler Minivans bolted to the cradle in unit in 20 minutes flat.
No Goofing around & air Snap On 1/2 inch impact & Snap On 3/8" inch air ratchet used.
Replaced the engine or trans and back together and driving in 4 hours.


The Old Pontiac Fieros were similar.
I remember changing out clutches in them.
Maybe 9 or 10.
I could get them done in 1-1/2 Hours back 1999.

I do see a Winters style Quick change rearend.
May just be the ZF Counter cluster gear & Mainshaft bearing end plate I see.


Be nice if quick change like a dirt track car.
Change the diff final drive gear ratio in 5 minutes time.

My guess is Longtimer the Brass at GM will set up the C8 so it can not be Drag Race Power shifted by a Street drag racer like me.
All computer control.


The original C3 Mid Engine Prototype the Head Engineers were Busted doing Wheel Stands Wheelies in it in front of the Main Doors parking Lot.
Front wheels off the ground for several hundred feet banging away at the gears WOT.
One Big Reason the C3 Mid engine was cancelled.
The Engineers were all Drag Racers. :cheers:

The thing about "Computer Control" is that there are no MFG computer controls that I have heard of that have not been "cracked" and modifications offered by the aftermarket. I doubt this transmission will be any different.

clutch replacement

if there are turbos or a supercharger, I would expect that would make the clutch change an even bigger job....regardless, owning one of these cars is gonna be big dinero….maintenance also will definitely not be cheap.
