My 00 Civic EX wouldn't go into any gear. The clutch is really mushy, and it goes almost all the way to the floor before there's any pressure. This is on a stock y8 with a stock transmission, exedy stage 1 and fidanza flywheel. Clutch, flywheel, and pressure plate have about 30,000 on them, but my stock lasted about 130,000 with me driving, so I don't think it's bad.

I let the car run for awhile and pumped the clutch, and eventually I got some pressure back to where I was able to get it into gear and drive home. I have noticed over the last few weeks that the friction point would seem to change... it would be normal, then it would be way down on the floor, then it would be fairly high, but I thought it was my imagination.

I would think the clutch fluid might be low, but it was too dark to check it. I haven't noticed any leaking fluid though. I wanted to get some opinions before I go out and start screwing with it tonight.

A leaking master/slave cylinder assembly would cause your clutch to feel slushy and not work correct.

this may sound stupid and i may be talking out of my butt, but, ive heard of people having tranny problems based on the spark plugs/wires they are running..most of them have been running the bosch's then when they switch to NGK they dont have the problem...thats just what ive heard.

bleed the clutch. will solve all your problems. air probably somehow got into the clutch lines (clutch fluid reservoir too low or something). go get a haynes or something, its really easy to do. guarentee it will fix it. let me know what happens.

Yeah, so thats totally wrong.


Anyways, your clutch slave cylinder or master cylinder has failed.

Once I got it into the light, I found that it was out of fluid. Filled it up and drove it around, and I still don't see any leaking anywhere, which is strange... fluid doesn't just disappear. But then again, maybe it does. I haven't checked it in approximately 174,000 miles - I've never even thought about it, although I check all the other fluids regularly. Probably still need to bleed it since it was apparently sucking air for a few days. I'll look that up tonight and give it a shot.

You really should bleed the entire master/slave assembly. Air could have gotten into the system over time, especially with that many miles. It might even be good to change the fluid out with some fresher fluid. And another thing that you could check is if the rubber hoses leading to and from the master and slave are still in good shape. Over time the hoses can get weak and very flexible and expand. On some vehicles once you get air into the master cylinder assembly its very difficult to get all of the air completely out.

dont forget to bleed it after changing the fluid. bleeding is easy, go buy that "one man bleeder kit" from autozone, $10. hook nylon hose to bleeder valve, put like 1" of dot 3 brake fluid in the bottle, put the cap on (that has a nylon hose that submerges under the water), have a friend depress the clutch while you open the bleeder valve, some fluid and air will come through the line then stop, close bleeder, pull clutch pedal back up with your hand (it will be on the ground) and repeat until no air comes out. and your done! took me like 40 mins to do myself and i got a good amount of air out.

One place to check for leaks is on your clutch pedal. If you have fluid on your clutch pedal then your master cylinder is leaking.
