Having difficulty shifting gears. Clutch pedal has to be to the floor to shift. Car is a '97, 62K miles, two P.O.'s never changed the clutch fluid which I just did & bled, got some improvement, but not much. Tranny, linkage and clutch r ok as is tranny oil. I suspect it's the throw out bearing as it was making noise awhile back, but then stopped. Question is how do I know if it might be the clutch slave cyl. I've heard that these fail, but I don't c any leaks and fluid in reservoir stays full. Can the slave or m.c. fail without leaking? Don't want to do the throw out bearing now if it's just the slave or m.c. (Have to save up $ for the throw out bearing fix which I know is coming in future).
Thanks very much.
