Driving my '81 today, everything in fine working order. Stop at a traffic light goes in to 1st when I get the green light and then clutch feels funny when I go to shift into 2nd. get it in gear with a little extra effort and then same strange feeling (like nothing there) when I depress clutch to shift into 3rd. Turn around and limp home with it getting progreesively harder to put it into gear. By the time I get home, won't go into any gear.

No fluid leakage that I could see. Just seems strange to occur all of a sudden like that and the clutch had been tip-top up until today.

Any thoughts on what it could be?

Thanks in advance.

My friend had a problem like yours. It was his mastercylinder, the fluid would bypass the internal rubber seal.

It could be that simple. Like the above posts hints at, look at the seal on the clutch master cylinder, then, maybe just adjust your clutch the normal way until you get it back in normal range. Test it by taking it for a short drive, and, you'll know you're getting your clutch back because it will go into gear.

I'm sure more will chime in that know much more about this than me, but I've had those exact symptoms on several occassions in both of mine.

You could have an assistant operate the clutch pedal and you watch the action of the clutch actuating arm which is connected to the slave cylinder.

If pedal action produces no movement of the arm, then you have narrowed it down to a hydraulics issue.

Check and top off the clutch hyd reservior, then check for leaks. If the res was very low, you might get off easy by topping off and then bleeding, but you still have to wonder where the fluid went. If there are no leaks to be found, then it's as previously posted, either the master or slave have failed. Its much easier to change the slave, so maybe start there first.

Something like this http://www2.northerntool.com/product/200322889.htm and some fittings will let you test the pressure just upstream of the slave. If good pressure, then the master is OK so rebuild/replace the slave. If very low, rebuild/replace the master.

is what it was with me. The outer rubber support of the center of the lollipop had worn down, due to age, weathering, oil dripping on it, etc...so it wouldn't shift into each gear properly since the linkage was sloppy. I put a "new" one on, and no more problems.
But, it may or may not be that with yours. Best way to check? From driver's side, slide under, take the lollipop and twist it back and forth. If you can see or feel the rubbery (round) center area loosening, there's your problem.

I sent ya an email, too....

I'm hoping that it's not too serious.

....your symptoms sound very much like mine one morning last year. And for me, it was time to buy a new clutch. It went south very quickly, with hardly any warning at all.

If it is a master/slave cylinder issue, you should be able to see signs of leakage at the offending party. Use a flashlight.

If it is the master, well good luck!!! Hope you've been attending your Yoga classes regularly, and you might be able to hold the "upside down under the steering wheel with a very complicated mechanism pose" long enough to pull it yourself.

If it is the slave, then its a walk in the park. Whatever the case, I'm sure you've read the numerous posts here that suggest replacement, rather than rebuilding these items. Avoid the trouble, save the drama for yo' mama, and buy new.

Good luck with it!

with not more than 15 psi (any more will can cause BIG problems)will help the clutch bleeding process.

... I left you a message a few days back also... but don't know if its the right number.

I'll be home tomorrow evening... 661-296-7277

I think you just got WARNED with a soft failure of your hydraulics... and that's not an opinion, its based on similar experiences...


My best,
