Disengagement problem, car won't stall when clutch depressed even in 5th gear!!

[Stainbox12]

As some of you may know, i had a lot of troubles with my car, regarding clutch issues. I had a problem where i felt somehow no pedal pressure with my centerforce pressure plate/disk. I have replaced, the master, the slave, i took out the pedal assambly and it was fine, i shimmed the pivot ball with 1 washer, i replaced the pressure plate and the clutch disk with a stock one. Now the car feels good when i push the pedal, i can feel that it enganges when its to the floor, but apparently its not disengaging. At first after i installed the disk/pressure plate, i could go in all gears with the car on without pressing the clutch pedal, so i made sure everything was tight and i adjusted a little bit the master rod, now it grinds through the gears without the clutch in, like its supposed to do, but whenever i press the clutch pedal and and put it in gear, the car doesn't stall. In my 5th gear, the car drops the rpm's just a little bit, and the tires try to spin just a little bit, other than that the other gears won't do anything when the clutch is depressed. So what im thinking, is that probably my flywheel is warped somehow, making it to not disengage. In my 5th gear i can hear some loud friction noise coming from the tranny when i release the pedal, which is not normal. Any help would be greatly appreciated.

are your axle shafts all the way into the trans? if they arent the car may just be spinnin that side of the trans if its an open diff. Had this problem with a sunfire once i think i know the noise ## talkin about also

Yes, they are fine as far as i can tell. any other suggestions?

I know this sound stipit, but it happend to me. check the bot that goes from the trans to the motor, right next to the slave cylider. Mine had came out and I had the same problems in my 92 AWD. If thats not it it sounds like you need more travel. Try changing the pivot ball and adding one more shim. Be carefull that the clutch disengages though, the last thig you want is pressure on the TOB when you are driving. Did you change the flywheel? You may need to check the step on the flywheel. With the noise you are hearing it sound like the clutch is not disengaging all the way and you have pressure on the pressure plate causing the TOB to make noise. Just my .02 Did you replace it to upgrade or was it worn out?

The only thing i haven't done is to resurface the flywheel. Im getting tired of dropping the trans already. BTW the slave looks fine, its brand new. Thanks for the help.

I wasnt talking about the slave cyln itself. Get some one to push the clutch in and watch the operation sof the slave cylinder, and see if youo can see the block and the trans seperate a little bit. When my bolt was missing it would push the tranny prob 1/8" causing a no shift problem. Good luck

All the bolts are in place. I checked it before and it doesn't move. I know what you mean, and im sure its fine. I think the last thing to do is to drop the tranny again, and take out the flywheel to get it resurfaced. Would a flywheel with a bad surface cause the clutch to engage but not to disengage?

The only things I can think of ...

(1) Slave cyl not releasing completely. Check to make sure that your shift fork completely returns to rest. You should be able to mount and unmount your slave cyl without it moving your shift fork.
(2) Flywheel step out of spec. This will prevent your pressure plate from making full contact.
(3) Bad tranny.

I don't think it would be a tranny problem. All this issue developed with a centerforce Pressure plate/disk setup with the car parked. Now im back to stock, but i never had the flywheel resurfaced when doing this. And i had some slipping issues back when the centerforce setup was working fine. So probably the flywheel is warped caussing the disk to not disengage or to slip somehow. something i didn't do, was to bleed the slave after the stock pressure plate/disk was installed, i just stepped it aside, assuming it wouldn't loose pressure, it didn't but who knows, ill give it a try, and if doesn't work, i guess i would need to drop the tranny once again.

If the new Centerforce was slipping, then you have a problem. With the sound you mentioned earlier combined with the clutch slipping, I would say that it is not letting the TOB come back all the way. If the TOB is riding on the pressure plate its kinda like having your foot on the clutch the whole time you drive. I would get in touch with centerforce and ask them. A shorter clutch rod at the slave ctlinder might solve the problem temporarily. Or take the shim you put under the pivot ball. It sounds to me like that could be the whole problem. Good luck

Oh to answer your other question a warped flywheel will let the clutch engage and not disengage fully, but I have rarely seen that as a cause. I would try the shim first (remove it)

You may be right luvmygst. Because i shimmed the pivot ball back when i was trying to fix the problem i had with my centerforce setup. Now im back to stock and the pedal itself feels so good, and i don't mean soft, but it actually travels till the point you feel it engages, but when i let it out nothing happens, i will try a shorter slave, because dropping the tranny is too much work, if that solves the problem, i might try taking out the shim on the pivot ball and getting the flywheel resurfaced. Btw the slipping developed without the shim, i shimmed it when i never felt for real that engangement point on the pedal back when i had the CF setup. Thanks for all the help guys i really appreciate it.

I was checking everything today, and i was ready to put a smaller rod. And i noticed that i can move the fork towards the slave cylinder with my hand when the pedal is not pressed. Is the pressure going somewhere, or is not bled enough? is this normal?
