Clutch/transmission problem

[JimmyJames1]

I have an S14 w/ S13 SR20. My problems started a few weeks ago when I was about to turn off my car. I had been driving for about 30 mins, and I parked and put the car in first gear. All of the sudden the shifter started shaking and my idle became very rough. I tried putting the car in neutral but the shifter wouldn't come out of 1st.

So I come back to my car about 3 hours later, and when I turn it on, everythings fine. About five minutes later, same thing starts happening while I'm driving. This time the car was in 4th and didn't wanna come out of gear. I finally get it back in neutral, but it won't go into any other gear. I've only driven it twice since then, but both times the car is fine until it gets warmed up. About five or ten minutes into driving, I always have the same problem. To get it going I have to turn off the car, put it in second, turn it on, and just drive in second.

The clutch has 9k miles on it and is a ACT HD street disk. I've already bled the clutch system. Where should I go from here?

Check and make sure the transmission is topped off with gear oil.

Well, I still had the clutch dampener on, so I took that off, but now I can't get any pressure back in the clutch lines. The pedal just falls to the floor. I tried bleeding the lines from the slave, and air comes out, but the pedal still won't come up on its own. Is there something I need to do to get pressure back in the lines?

how are you bleeding the system?? look under the dash and look if you see any oil from the master cylinder. if so change the cylinder. try bleeding the master cyl. first.

Hydro clutch systems are really wierd. The best way to bleed it is to get a cup and fill it halfway with brake fluid. Run a line from the slave to the cup and have a buddy pump the pedal. When there isn't anymore air bubbles in the cup then your done. voilah!
