clutch problems- wont go into gear when car on/goes into gear when off

[Talon00b]

alrighty boys the car runs perfect but theres something wrong with the clutch. The mechanic put a brand new clutch in the tranny and I "thought" it was ready to go. the clutch fluid is full but i donno if its new stuff or the old stuff. heres what happens: when the car is on, the car doesnt wanna go into gear...but when the car is off it goes into gear fine the clutch pedal feels really loose too i put in a stage 1 clutch kit so it sould feel hard then this do i have to bleed the old fluid out or was there something i should do since its a new clutch?
thanks guys

Sounds like you need to bleed the clutch line. Just about any car will shift gears when the engine is off even if the clutch isn't engaging correctly.

Bleed your clutch and chances are your problem will be solved.

This should help, if you don't know how to do it.

It's towards the end of the article. Maybe midway through it. It first talks about replacing the slave cylinder and then goes into bleeding the system afterwards.

My car is doing the same thing, and bleeding didn't do anything for it. Did you resurface your flywheel? You may be having disengagement problems b/c of having an incorrect step height.

Hmmm When I got the Tranny i gave it to the mechanics to install (### i ran outa room wqith my other toys and he said he reserfaced the flywheel i donno why its not i could see maybe he didnt bleed the fluid (and he told me he didnt put any tranny fluid in so mabe he didnt change the clutch fluid as well? but its full) so i donno ill try bleeding it tomorrow and see what happens then if nothing back to the drawing board

I think what's happening is your clutch isn't fully disengaging becuase of a poor clutch pedal adjustment. How far down does you clutch engage/disengage at? All the way up? Half way to the floor? All the way to the floor? My car was doing the same thing, wouldn't go into gear while running, but when I turned it off it went into gear just fine. My clutch also didn't engage/disengage practically till my foot was through the floor. So I'd recommend adjusting your clutch pedal. Worked for me.

The slave cylender or the clutch master cylender could also be bad. Have someone check to see if the slave cylender rod does not move back in while u are holding down the clutch. If it moves back in it could be a sighn that one of them are bad. Since it is not holding the pressure on the clutch fork. good luck!

What clutch kit did you put into the car?

One other ugly little thing to check on a 1g is your clutch pedal assembly. They wear out and have to be replaced/repaired on occasion. If after the pedal comes up you can pull it up more you probably have a worn pedal assembly.

Crawl under the dash after pushing the clutch pedal down and releasing it.

Look up at the assembly and find the big coiled up spring on the clutch pedal shaft. That'll be next to where the master cylinder comes through the firewall.

Push the pedal in a bit and see if it moves. That's just to see if it is the right one. You can look for a leak while you're under there.

Now once the pedal is back up, try to pull it up more and see if it can. Then push it back down a bit and see if it can move at all without the master cylinder rod moving.

If the pedal moves without the master cylinder moving you have a worn assembly and will need to pull it out of the car and repair it. Have fun if you do, it's a royal pain. If you know someone who can weld in tight places they can weld it together while it is in the car bit it won't be fun or easy either.

What clutch kit did you put into the car?

A Spec Stage III and a Fidanza flywheel. Everybody is listing things that he could fix, and I've done all of that. Slave, master, SS line, welded pedal assembly, adjusting the pedal, longer slave rod, and none of it worked for me. So Spec is taking back my clutch and flywheel and checking to see if they can figure out anything.

Dream on, Did you replace your fork and pivot ball? That's about the last possible thing it could be.

Or, are you a 7 bolt motor? I recall that crank walk can cause issues with clutches disengaging..

 

[Dream On]

Yes its a 7 bolt (damn 6/92...) and I did replace the fork and ball, and shimmed the ball with a very thin washer (so thin that I didn't think it would even do anything..). It didn't have any problems before the install, and I've got 130k miles. No symptoms or anything. Just cause you have a 6 bolt doesn't mean you have to try and scare me about having a 7 bolt.. Its definately something with the clutch or the flywheel. Spec has almost convinced me its the flywheel.

 

[eclipsh]

Yeah, but I've got a flimsy 3 bolt rear.

You probably already know this, but just in case...

Check how far the fork has to push before it makes contact with the pressure plate. If it isn't in the center of the opening on the tranny when it makes contact then it isn't shimmed enough. If it is closer to the passenger's side you're definately way off.

It's closer to the driver's side. Trust me man, I've done everything I can think of.

 

[nsxwidebodied]

to me this new clutch deal smells like FRAUD!, are you shure he put the new clutch in??, buecause i had the same problem, and when i took the clutch out, the disk was all in pices, so i replaced the clutch, and everything is back to normal, so you might want to make shure that he replaced the clutch, or maybe he put on a used one that has gone bad now, and kept your new clutch, good luck with that

 

[eclipsh]

It's closer to the driver's side. Trust me man, I've done everything I can think of.

I figured you had, but you never know what people will miss. "OH, you mean I have to push the pedal in ALL the way? Really?"

nsx: That's why you go by a mechanic with a good rep you know you can trust, meet them face to face and see what you think.

 

[Dream On]

Yep. Thats where the car is now. He said the specs are off on either the clutch or the flywheel, so I'm sending them to SPEC, who is telling me they'll fix either one, even though its a Fidanza flywheel. Really good service and really nice guys. Hopefully it all gets straightened out. And sorry that I kinda jacked this thread..

 

[eclipsh]

Meh, it's on topic, I wouldn't worry about it. The info is still pertinent and usefull.

 

[Dream On]

A little update, even though this isn't my thread...I got my clutch and flywheel back from Spec, and they said things were right on. They said the "cleaned up" the flywheel a little, and replaced the clutch anyway. I'm going to try and get it to work this weekend.
