All my problems just went away
 

I just threw in the LS7 clutch and with about 490 miles on it, it wouldnt shift at all if you tried to slam it. But now with 575 miles I'm slammin em' like never before! I have been trying to bleed this thing forever, and nothing seemed to be working. So maybe if you just installed the LS7 and the shifts seem notchy, just put some miles on it and maybe things will go your way.
