Now, keep in mind, the shop I had it done at was a small shop in a small town, and it took forever to get me in. Once I did get the shop to put it in, they didn't bleed my master cylinder at all, they only gravity bled the slave by filling the master as they let the slave stopper loose.
So I got it back w/ almost no peddle.
Make sure if you get the slave replaced at a shop that they put the little plastic sleeve on the new slave/master line (it's for the quick-disconnect feature), otherwise you'll like never be able to get the master line detatched from the slave again, and you'll have to break the slave cylinder and cut the slave part off the master line after the trans is out.
Just thought I'd throw it out there since that's what happened to me lol.
