Hehe, those slaves are a pain.. Conventional bleeding doesn't seem to work for these things. What method did you use? Are you using a power bleeder, or the pump method? Power bleeding doesn't really work for me at work, and I never really tried the 2 man game.....but here's what I do:
1. Remove the slave cylinder from the tranny, but leave the line attatched.
2. Find somewhere on the body of the car that you can push the slave rod into.
3. With your wrench at the ready, start to push the slave rod into the slave by pressing it against your object of choice.
4. Once you start it moving, crack the bleeder screw, and push the slave rod all the way down, and tighten the bleeder.
5. Let the slave rod extend on it's own, and repeat the procedure a few times, or until all the air is out.
What this does is it pushes the air and fluid out when you compress the slave cylinder, and when it comes back out on it's own, with the bleeder CLOSED, it sucks fluid out of the reservoir.
Works like a charm for me.
ANOTHER method that I was told works, but never could get any results from, is to take an old oil can squirter with a small nozzle on it. Fill the can with fluid, attatch a vacuum hose from the pump to the bleeder, and pump fluid INTO the slave, and into the reservoir. Theoretically, this pushes all the air up and out into the reservoir.
It's worth a shot.
