The clutch is definitely not disengaging all the way. The rear wheels begin spinning as soon as it is put into first gear, even with the clutch pedal on the floor.

I removed the aluminum spacer from the slave cylinder and shined a flashlight in the bellhousing. I can see the clutch fork moving, and I can see the fingers on the pressure plate moving as well. So it definitely is working, just not working ENOUGH.

I tried placing the slave cylinder closer, which didn't help. The hydraulic system just compensated. Same deal with moving it farther out.

It almost seems like the hydraulics are the problem, like they're developing insufficent force to pull the pressure plate far enough. It didn't really seem to travel very far at all. But I didn't see any way to bleed the damn thing. Any ideas?

Also, does anyone know a safe way to manually operate the clutch fork and see if the clutch will release? That way I could see if the clutch mechanicals are working properly or if something is stuck or binding.

Unfortunately due to the design of the T56 bellhousing I really don't see a way to get the tranny out of the way and just operate the clutch.

Are the hydraulics new? If not, were they bled incorrectly?

There also is two types of hydraulic assemblys. No one has any definite reason as to why, but my theory is that the two setups have different piston travel. Mine is very short, but it works. I think I need the other one, but I'm not sure. See if the dealer can find out which setup you have and what the difference is. If you find out PLEASE tell us!!!

They were new, but they'd been in and out of the car several times. I bled the system tonight, and it definitely had air in it. That problem has been fixed.

However, there was absolutely NO improvement in the disengagement at ALL.

Any ideas?

 

Now I'm thinking the clutch fork might not be installed correctly. Anyone have a link that shows how to do this?
