Slave Valve Questions?
Having to replace SLAVE a second time within the year. I'm thinking of
doing it myself. The Chevy dealer charged me $163.82 for the SLAVE,
$172.00 for 2 hrs. labor. TOTAL =$335.82. QUESTIONS are: Is it worth
doing myself? Is it wise to purchase from a normal PARTS SHOP instead
of the dealer? Would the SLAVE VALVE be BRAND NEW or REBUILT (does
it matter)? IS IT ABSOLUTELY NECESSARY TO BLEED SLAVE BEFORE
INSTALLING IT INTO HOUSING? I don't think the mechanic bled the SLAVE
prior to install the last time it was done. What will happen if it is not bled
before install? Finally, if leaking fluid is inside HOUSING, does it have to be
removed? What happens if it is not REMOVED? THANKS SO MUCH!

well I am in the same process right now,I`m doing it myself,not the easiest but patience is key especially when the bleeding starts.On my 88 you don`t have to remove slave to bleed it,but if you can before you totally install it could be better,cause bleeding is gonna be a test of patience.Its no way dealer could not have bled it cause if air is in there you will not be able to go in any gear with engine running,thats my opinion,and thats what I`m going through at the moment. I`m going out today and get me a mityvac to help me get the air out.I hear it works well.

Yes it's worth doing yourself. And bleeding the system, contrary to popular belief, is very easy. You can get a new slave for a bout $100 from either Corvette Central or Superior Chevy (the only two places I've dealt with). The slave will be brand new. You do not need to bleed the slave prior to install. Just check that the lock ring and boot are seated firmly inside the cylinder before you get started. Don't worry about the fluid, it will just drip out onto your garage floor. 
Before buying the new slave I would recommend that you remove the old one first and just check that the lock ring is in place correctly. My bet is that is where your problem is. Heck, it can't hurt and may just save you a c note. I had/have a brand new one out of the box that was not set properly.
I hope this helps.
BTW: what year car do you have??
