I replaced my master a year or so ago and although its fine for regular driving I haven't been able to powershift with it.

I could before, can't now...I assume this has to do with the bleed procedure.

Has anyone tried this with sucess:

I have all the stuff, might give it a shot.

 

We have done this a few times on cars with great success. I highly recommend doing this if the bleeding from below does not give you the results that you are looking for.

Great, thanks for the reply.

Give it a shot tommorow.

 

So, this procedure doesn't require any use of the bleeder valve down on the slave? Basically, the vacuum applied brings the old fluid into the mity vac cylinder as you push in the clutch, and then as you release, new fluid from in the clutch resevoir flows into the slave? I'm a bit confused....
