Default throw out bearing or new clutch?

Well, I've just recently got my car back from the shop. It is making 501 and 47X to the wheels. I have a T56, and the car itself has under 20,000 miles on it.

When I push the clutch in, it doesn't pop out all the way, and it feels as if there is a bit of play at the top of the clutch (all the way out).

this morning, one of the cooler mornings I've driven it since I had it back, The clutch is releasing just about at the floor, and once or twice, it was very hard to get into first gear, and the clutch barely came off the floor and wouldn't come up any higher without me helping it out.

Any recommendations? The clutch is a Spec stg. 3 by the way. Anyone know how those fare with that much power?

Thanks in advance.

Have you ever changed and bled your master clutch reservoir? Is the fluid discolored and/or does is smell burned?

Yup, looks like there is hardly any fluid in there, and it is a bit dirty...

How do you bleed that? I don't imagine its like brakes... never bled a clutch

I suggest the use of a mighty-vac to pull the air out of the system. You need to vacuum from the actual bleeder valve off the slave and from the reservoir that feeds the master. If you haven't done this before then you may want to consult someone locally (a shop or other experienced LS owner) that would be willing to assist you. It can be a little tedious but it is a necessary evil when replacing a clutch on an LS1 equipped car.

Any recommended fluid? I have some dot 4 that I had when I had my motorcycle. Would that be sufficient?

I am a big fan of Motul RBF-600 fluid. It has never let me down and I have used it in a number of vehicles that see track use (road-race) regularly. Thanks,

When bleeding from the slave do you just place the vac over the hole in the bleeder? Crack the bleeder first right? How much pressure should be used?
