On my 96 cobra the clutch pedal starts to occasionally pulsate or vibrate pretty bad. This will even happen with the tranny in neutral. I just put in a new tranny, clutch/pressure plate, and flywheel and it's still there... any ideas?? thanks

i've occasionaly encountered the same probrem. Mine was sort of vibration sounded like that comes from right behind center A/C vent. when it does, its really freakin' loud and annoying.
Turned out the my quadrant was vibrating. as soon as you toutch quadrant with tip of your feet, it stopped. Never figured out why.

then i changed clutch. Along with TOB and everything else. Now vibration is pretty much there to stay. same sound, and same location. Only this time, i've noticed that vibration corresponds with TOB sqweeling. From that, I have concluded that noise is something/somehow caused by TOB, and coming up through clutch cable. And to prove this, when vibration and TOB sqweel was there, i wiggled on clutch cable from engine bay. and both stopped immidiately(as long as i kept wiggling cable). can't imagine what it might be tho. If it happened everysingle time, i might have thought may be my pressure plate finger is bent, flywheel is not bolted on straight, clutch folk is dmg'ed. But as freaquent as it happens, its not everytime thing. So from that, i think its not from any i've just mentioned. Mostlikely something to do with tob being bad(like m SPEC one was), causing some sort of resonace, which traveling up through clucth cable, then vibrating clutch pedal assembry.

this is how far i figured out. Now as far as fix goes... i'm still trying to figure it out.
Hope this gives you some idea what you might be dealing with

Are the pedal, cable and quad 'aligned'? Often, with an aftermarket quad, you need washers or some other type of spacer(s) to align properly.

The problem I am dealing with now on my Fox. The pressure plate I think is warped from incorrect storage when purchased new. I just installed new flywheel,clutch, pressure plate and the vibration sitting still with the clutch in and revving the engine will shake you apart. I am taking everything back put getting a new pressure plate and clutch and putting my old flywheel back on. I am going to try to find someone who can check the balance of the flywheel because I rather install the new one back on if it is ok. I am going to remove this weekend and will report back.

I had the same issue with my '96. Turned out that it was the pressure plate fingers... The dealer changed it out under warranty and got it fixed.
