installed new clutch...BIG problem..please help. Options

[NOMIEZVR4]

aright guys, here is the situation:

the car doesn't want to go in gear when its started. no gears, it refuses to go.

if I shut the car off, I can put it in gear.

If I start the car while it is in gear, the car just starts moving as soon as I crank the motor even though the clutch is depressed.

I just installed the bm lsd insert and a act 2100 with a resurfaced flywheel. We filled the tranny with 2.5 quarts of pennzoil syncromesh aka gm syncromesh. During the install, we had a HARD time with the slave cylinder installation. It was just a tight fit. Yea I know its not supposed to be a biggie, but it was.

Im thinking maybe the problem is either the slave cylinder or the throw out bearing. when I press the clutch, I can see the lever move. During the install, I made sure the rod didn't come out all the way, so that I wouldn't have to bleed the clutch system. I think out of the two its most likely the throwout bearing. What do you guys think?
