Need help w/ bleeding a clutch!

["Avram Dorfman" <dorfman@est.org>]

I'm having trouble bleeding the clutch in an '88 80 quattro. Here's what happens:

 

1) we open the bleeder valve

2) we step on the clutch

3) Air & a little fluid comes out

4) we close the bleeder valve

5) we lift the clutch off the floor (it doesn't come up on it's own), and there's a little resistance

6) we open the bleeder valve to do it again

7) air gets sucked into the bleeder valve as soon as we open it

 

it appears as though we're creating a vacuum in the line when we lift the clutch. For some reason, fluid from the reservoir is apparently not going into the line to replace what came out when we lift the clutch.

 

Here's the background: We just put the transmission back in. We bled the clutch while it was hanging free & the trans was out, and it worked fine. Is it possible that we did something wrong when we put the slave cylinder back in? Can anyone thing of anything else that migh be causing this problem?
