97gst, I had a clutch fluid leak that went ballistic, so I decided to swap both cylinders and use a direct ss line. Got everything together, got everything bled, went to go and that's where the suffering started. Can't get into any gear except reverse (reverse has a pretty bad grind to get into) while the engine is running. Shifts fine while off.

I have the clutch master linkage almost unscrewed, the slave can freeload (be compressed by hand), but not after a very short pedal travel. The pedal travels very smoothly (no sticks or "lumps" in feel: even consistent pressure) through most of its range, but stops suddenly and firmly before reaching the floor, as far as i can tell, this may be the end of master cylinder travel, as there does not appear to be any other mechanical limit to travel. As for the slave, it operates under pressure, stopping before reaching the bell housing (i can fit a finger between).

I've bled and bled and bled, haven't seen a bubble since the first 5-10 minutes (I also bled the slave by pressing it in through its entire range of travel with the valve open, allowing to to return with the valve closed.)

parts are the extreme psi ss line, and exedy mc401 and sc581 ("equal" subbranding).
