Default Sticky clutch mysteriously disappears

Ok quick history.....my clutch pedal was sticky...I pulled the fork, slave, etc. and greased everything. Problem would go away for a few weeks, then return. It's been sticky for a few weeks now.

TONIGHT.....On my way home from dinner, there's a lady waving me down who's stuck on the highway with no gas. I pull up, she's got no phone so I make a call for her. The police pull up, and I get out to chat with the cop. At this point my car has been idling for about 5 minutes.

All is good with the lady, so off I go. I get in the car, go to push in the clutch. First thing that comes to mind is something broke. Only to find it was my clutch had returned to normal pedal feel, just like when it was new. It went from stiff to like new in a 5 minute idling period.

Anybody care to speculate what happened? I'd love to have a permanent fix for this. My plan was to grease everything the night before Fall Colors, to get me through thew weekend. But obviously something else is up

It's been known that even from the factory, some cars never got a liberal dose of the proper grease on the splines that the throw out bearing rides on. It is my belief that, in time, the lack of grease increases the friction in the T.O. bearing movement to the extent that metal ridges can build up and impede this movement. Perhaps in your case, enough oddball combinations of things occured such that those ridges may have been smoothed out. If this dumb guess is true, if you do nothing, in time, it will get sticky again when new ridges get built up.

Well...I do have an 04 trans, and I was very thorough when greasing upon install.

But I appreciate the response!

This must be some new euphemism of you younger members. I always thought stiff was "like new". And, as I get older, I find that I now need longer than a 5 minute "idling period".

Bill, that's the best I can do with your thread as I have no idea what's going on with the clutch pedal feel .

It's a mystery, but maybe that's why my clutch never sticks (knocks on wood). My car idles for 10-15 minutes 8-14 times each month while autocrossing!

Relative to XVIPER's comment on splines... here's what the parts look like. Part #1 in the upper drawing is the collar that the TO bearing rides on. Are there splines on that part and the inside of the TO bearing? Or does the fork (#4 upper) hold the outer part of the TO bearing from spinning?

TO does not ride on splines, the disc does. The surface of part #1 is smooth, as is the inside of the TO bearing.

The TO bearing has a high spot on the outside to keep it from spinning, which is held by the fork.

Would it has anything to do with clutch fluid?

otherwise, I'm thinking fairy s2000 god mother granted it as you were doing good deed.
