I just put a spec stage 3 clutch in along w/ a rebuilt engine and LSD. Engine is up and running good now but when I was ready to take it for its first spin it wouldnt go into gear! It shifts great while the car is off but wont shift into any gear when its running. I've checked the master and slave cylinders for leaks and it seems to be holding good. Bled the lines as normal. Bled them some more. Still wont go into gear.
Any ideas on why it wont engage?

I bought it from pghsebring b/c he said he was upgrading. Id rather not think that it was a bad spec 3 since I just bought it and it worked on his car.
