Clutch change and no pedal pressure

I'm running out of ideas on this and I'm hoping someone can steer me in the right direction.

I have a 94 3.4l v6.

The clutch seemed a little weak so I replaced it. Now the pedal has almost no pressure. There is enough to return the pedal, but it doesn't feel like enough to actually move the clutch spring.

I pulled the boot off the transmission and watched the clutch fork move the throw out bearing forward and against the pressure plate fingers, but it seems like it could probably go a little farther forward. That, coupled with the soft pedal led me to believe the hydraulics needed to be bled, but I went out there tonight and did not see a single bubble rise out of the reservoir when the slave was pumped.

I am 99% sure that the clutch disc is in right. It had a blobbed stamp on it, but I'm sure it said "flywheel side." Plus, I think the problem would be different if it was flipped.

One other clue. When reinstalling the transmission, it didn't slide in too easily. I figured that it didn't because the input shaft had to slide into the pilot bushing at just the right angle and it was difficult to get it there with just one set of hands. Otherwise installation went smoothly.

Should I try bleeding the hydraulics again? The Haynes manual says to loosen up the master cylinder and then gives precise measurements on how far to move the slave cylinder rod. I have no clue what the purpose of loosening the master cylinder is supposed to accomplish.

Otherwise, do you think the pilot bushing is too tight of a fit and it could be binding?

Thanks!
