trashed the tranny... And i think while its getting rebuilt, that i should replace the clutch. (stuck in 4th gear)
I'm thinking the LS7 clutch. Is it a direct replacement?

You can use the LS7 clutch, but you have to use the LS2 flywheel. Your LS6 flywheel wont accept the LS7....
I had my tranny stick in 4th gear at the dragstrip. It ended up having a sheared key, bent the shift fork (aluminum) the 3-4 syncro was replaced, and 3rd gear was replaced because it had some wear. I ended up spending about $1,100 with me doing the remove/replace labor in my garage.
The Corvettes are no fun when it comes to changing a clutch.

Well i found a well known local shop to do a complete rebuild (with steel shift forks) including labor, for $1200. I just think i should put a clutch in it, while its apart. No sense in taking it all apart twice.

Those fail often. You have to take all that crap apart just to change a cheap item, definately get that done. ~Joshua

Yeah, make sure you add a new slave cylinder. (between the tranny and clutch.)

I am sceptical about the LS7 clutch. I have heard some not so good things about it like not being able to hold up to hard launching. I was thinking of going that route a while back but now I will go a different way I am just not exactly sure yet. Do a search and read about peoples experiances with the LS7 clutch before you buy one. Just my .02.

A stock LS6 clutch would take a 5200 launch with minimal slip and do so repeatedly. One Fall day in 2004 at an Atco track rental, I hot-lapped my stock/CAI 2002 Z06 on MT ET Street Radials...three passes back-to-back with no cool down of the clutch and the passes about four minutes apart. Three launches at 5100-5200 gave a very strong leave, with 60' within a hundredth of 1.64.
An LS7 clutch on a stock 2006 Z06 won't accept one launch of 4200, or even 4000 without glazing the clutch and requiring an hour's cool down.
Now if you drop the launch rpm to 3500 and get the clutch out fast and then, and only then, start the throttle squeeze...the LS7 clutch tolerates that. If instead you get aggressive with the throttle before the clutch is engaged, it will glaze instantly...and will do so even at 2800 or 2500. The clutch material (PP and rotating disc) simply are slip intolerant.
My LS7 clutch (C6Z) is 100% fine at high rpms and on the shifts. Very positive. No issue. Provided it wasn't slipped at all on the launch.
It is at launch where this clutch is a supremely weak performer.
That would seem to indicate the issue is heat intolerance rather than clamping force.
