Hello,

This is likely going to sound like a very dumb question, but I'm still learning. I recently had my MN6 transmission in my 2001 C5 replaced by an MN12 (under warranty, plus a small incremental for the replacement). I have seen on the forum that, when replacing the clutch, that many seem to prefer the Z06 clutch on their regular C5's...
a) is this because the Z06 clutch has a better ability to handle power than the standard C5 clutch? (if not, why is it favoured?)
b) would my MN12 install include this new clutch as well?

Any guidance would be greatly appreciated.
Cheers

The Z06 clutch can hold a little more power.. It's a good clutch for mildly modded cars.

Plus the LS6 flywheel is lighter, and the hydraulics are better.

And no, it's not part of the MN12 install.

I don't think there is a different flywheel between the LS1 and LS6. I could be wrong. Wouldn't be the first time.

Thanks for the feedback guys - Dope, I wasn't sure what you meant - did you mean the install wouldn't include the flywheel, or the clutch? (I was assuming the MN12 install would include the Z06 clutch?)

The clutch is in the front of the car next to the engine, and the tranny is in the rear next to the differential, so no, it does not have to be part of the tranny install. You should do the tranny at the same time since the clutch install means moving the tranny anyway....might as well do that clutch while the tranny is out of the way. Also, the clutch and flywheel are essentially a single unit, so do the flywheel at the same time too.

Here are a couple of web pages I quickly put together on drivetrain and clutch R&R's that I helped some buddies with recently. The clutch is a Z06 clutch install in a 2001 coupe.

Lucky guy.....how does the accelleration feel compared to your car before?

JasonS

There was definitely more pickup than before (*felt* like less pedal was required to accelerate, but it might be a placebo effect just because of my excitement to get it) . I wasn't able to give it a thorough testing as I presume I need to go through a break-in period again??? It's hibernating for the winter, but will be back out again in April.

Yeah it should feel like there is greater accelleration because there is! It's the equivalent of swapping a 3.90 rear end in place of your 3.42s.
