Shifting from 1st to 2nd last night, the clutch went staright to the floor and there was zero pressure. I was very close to home and managed to get back to the drive way and get into neutral to stop the car. Have not looked at it yet, but I am guessing the slave cyclinder is the problem. Tranny sounds fine, in that there are no rattles or noise and I remember when putting in the SPEC 3 last year the actuator shaft was slightly bend. I am thinking it collapsed.
Any one know the price on a new slave cyclinder setup?

 

Well on my thirdgen when my pedal went to the floor like yours did the pushrod fell off the pedal!!! I learned to drive without a clutch. Otherwise, I have no idea how much parts for you will cost. Good luck to ya.

That happened to me once, if the pedal just flops there im 99% sure the pushrods just fell off the clutch.

 

One of the nuts that holds my slave cylinder on one time came loose and fell off. The slave cylinder went crooked and snapped off from the tranny when I pushed the clutch in. I ended up buying a Raybestos slave cylinder from NAPA/Autozone. They are alot cheaper than a new GM cylinder, however I can't remember the price. Somewhere between 20 and 60$
