Saab 9000 Breakdown #2 - Slave Cylinder

[Ianumunro]

Thanks to one Matt Walker, my Saab's newest case of the no-go has been diagnosed. The car's tantrum is a bad slave cylinder. So into the transmission housing I guess. And, again with knowledgeable advice, I figure it'll be best to replace many of the clutch's brothers and sisters while I'm in there.

But it's dangerous to go alone as I've never set foot in transmission housing before and would really like to not wreck it.

Yeah I had to look that up. Apparently not that uncommon, though I'm happy to have not run into it. That's just mean.

The T56 manual trans in the Corvette/Camaro is set up the same way. I think DJ had something happen with his LS1 M3 where it all got put together and the slave cylinder immediately failed... because I remember helping him pull the trans back out of it to put a new slave on it. Such a pain.

Ian, definitely do whatever else you can while you have it all apart. Pulling a transmission isn't the worst task, pulling it more than once is much more of a pain.

So Ian did his due diligence and found a full diagram of the clutch, pedal, slave, brake reservoir setup. Following that diagram we followed the lines from the reservoir, to the master cylinder, the lines to the slave and then the lines went into the bell housing. Considering his reservoir had full fluid and none of the other lines were leaking (and the slave cylinder went in BMW and it was pretty much the same symptoms) so I called it the slave. I can't imagine what else it would be.

The pedal goes down and doesn't come back up.

I don't think you're wrong, it's classic slave cylinder symptoms. Just sucks where it's located.

I've been looking more and more and I cannot find conclusive evidence whether it's in the box or not. The diagram has it resting on top on what is considered "Early 9000's", which I assume mine is since mine is from the original generation. I have been trying to get into contact with the foreign auto repair mechanic who used to have a broken 9000 on his property. I'll also consult a few forums and be back.
