clutch install problems! just changed the clutch on my 94 z28 m6 and now it's hard to shift gears and it won't go in reverse. i put a stock replacement clutch and a new slave and bled it. it's like its not fully releasing the clutch. when i had the car lifted up if you put it in gear with the clutch fully pressed in, the wheels start to spin. what could it be?
Incomplete disengagement could be it. I have been down that road. Hard as hell to get in geear and especially reverse.
First bleed the hydros by pumping the crap out of it.
Also if the disk thickness is too big as a result of the marcels (thin springs between the facings) being out of spec, this will happen. The two disk facings will decompress (again marcels) when the clutch is disenaged, if the facings are not fully decompressed by the time pedal is released then the clutch will drag and cause this problem you are having.
Two options. Get an adjustable master cylinder that has more travel or throw. Or replace the disk again.
Stock like disks all have marcels which look like z-bend springs between the facings, this reduces the chatter of the clutch but also weakens its grip some. High performance disks dont have marcels so decompression of the disk is never a problem and grip is improved.
