After i replaced my clutch it wont disengage fully. i have shimmed the flywheel b.c it is .30 over completely beld the hydrolics, and replaced the slave cylinder. I am completely out of ideas. Background info i have a kevlar clutch that is a resurfaced stock disc. I bent a driveshaft and broke the bellhousing in a 3-4 shift and ripped the center out of a brass clutch (if any of that helps anyone). Any help would be appreciated.
Thanks

 

I had the exact same problem and I can assure you I have the answer.
I installed a brand new LT4 pressure plate and had my old LT1 disk relined with kevlar. The clutch would not 100% disengage making almost impossible to put it in gear, especially reverse. It felt like you were going to break the tranny. I had my transmission out 5 times looking for the answer, so here it comes.
Your clutch disk is slightly to thick which makes it impossible for the pressure plate to fully disengage, its barely rubbing still trying to turn the tranny..
After I compared my rebuilt disk to a brand new organic disk it was .020" too thick.
I installed that organic disk and it worked perfectly.
Put the calipers on your clutch disk (dont compress or squeeze it)and I will bet its too thick. Stock I think is .218" +/- .003

Also there is no need to shim the flywheel, it will net you nothing and the hydraulics are self bleeding, just pump the crap out of it. I am going to go with a kevlar disk again but I will purchase a Spec disk instead of rebuilding.

I was at my wits end too, I promise you its the disk.
