Brand tex clutch, brand new master and slave clutch stopped disengaging Hi i have about 400 miles on my brand new setup (twin turbo, forged motor, built tranny, text clutch with all new hydraulics) the tranny shifted fine for about 2 weeks. I go to do some tuning last night and now the clutch doesn't disengage at all. If i am moving i can rev match and get the car into gear but if i put the clutch pedal to the floor it just slips and doesn't fully disengage. The clutch has never slipped and still doesn't, the fluid never leaked out, and i never got a chance to beat on the car. The fluid probably got hot but that's it. I tried bleeding it really quick but it didn't make any difference whatsoever. The car looses pedal pressure when running in nuetral and looses almost all pressure if i rev it up to like 5k. I am going to try to bleed it with the mityvac from the resivoir but i doubt it will help. I do not want to pull the tranny. I am thinking i might be able to get it to like a Cottman transmission to see if they can fix it and warranty it.

I had jenning's engineering do the tranny. He did everything from carbon fiber synchro's to the viper mainshaft. I know this is a weird problem and is even weirder that it ran absolutely fine until last night. I just searched all over for my mity vac and can't find it but i don't think the problem is air in the system if it won't disengage at all. If i uplug the hydrualic line i can't move the pedal so i don't think i have a leak in my line or my master. I really can't take anymore issues.
I let the car cool overnight and i went to work on it this morning. Nothing changed as far as engagement but it did lose some pedal pressure. The unusual thing is that the slave disengages but not fully so all i can get the clutch to do is slip but no fully disengage.

The brand new 02+ slave that comes with the textralia clutch. That's why i am so stumped. If i can't figure it out by tonight i am just going to take it to cottman since i don't access to a lift anymore and whatever they do should have a warranty.

Thanks for your time Joe. I dropped the car off at Cottman transmission and hopefully they will have time to take a look at it tomorrow.
The problem is i did the install myself (and i am an idiot when it comes to cars) but i did everything at once (engine and transmission install) and was pretty thorough about torque specs. The only thing i wasn't too sure about was the pilot bearing which was installed with the solid metal side facing the crank so the input would be pushing the whole bearing into the crank and not just the middle portion. I don't think that would have anything to do with the tranny engagement. I lubed up the input shaft with the GM version of the valvoline grease sold at autozone. I don't have any weird vibrations and the car runs smooth (i made sure to line up the PP and flywheel with the balance marker). I think the slave somehow is broken or possibly moved. When i installed the slave the bolt holes were slightly stripped (i didn't receive the original tranny i had sent out for the work) so i couldn't get the bolts really tight but i was on a time crunch and needed the car together. If the bolts came undone then shame on me but it was a progressive problem that happened all in about an hours time so i really don't know. At first i could still get it into and out of gear but it was sticking which turned into it not disengaging whatsoever.
I will post an update as soon as the car is taken apart and assessed as i plan to be right there watching.This is an unusual problem that probably has an easy fix i just need to know how it happened in order to prevent it in the future.

Update!! So i had the shop tear down the car and pull the tranny out. The first thing noticed was some scratch marks in the bellhousing and some possible bent fingers on the PP but other than that everything looked fine. I had them pull the bellhousing and we saw a dow missing from the flywheel. So i guess somehow the PP got warped and that's why it wasn't disengaging but ran fine before that. We pulled the PP and the flywheel had little ridges all around where the clutch disk was slipping( meaning when i slipped the clutch to get the car moving as the clutch never did slip when fully engaged). I don't know if this is normal or not (i ordered the billet flywheel) so i hope to find out when i have a talk with Jeff later tonight. I contacted Pete and he was more than eager to help out. I didn't have any worries that Textralia wasn't going to do their part to help out but i just didn't know if i would find an obvious problem.
I didn't even think of it at the time but on the way home i noticed some nasty vibrations that i thought may have been caused from a missing cylinder (i burnt through a plug wire). So i assume those vibrations were from the P/P.
When i get some more info i will post it.

Yes i found out why it stopped working. It was all my fault as the clutch worked fine for 2 weeks. A bolt had started to back out of the P/P and that's it. I didn't use any thread locker when i installed the clutch (this was my first time doing something like this and i was working alone but now i know). Unfortunately, i sold my jack and jack stands other wise i would have fixed it myself. The guy doing the work should be finished today. I hope everything works fine.

. I still have suspision that it may be because of the inconsitant pedal that I have, sometimes it is firm and sometimes it is softer.......... 
Still waiting to hear a response back from Jeff and Pete.Does anyone have any idea or advise on what it may be???

When i talked to Pete he told me not to replace the slave but i did anyway. They sent out a new P/P that had a different hat and different fingers on it. The clutch works just as good as it did before but now i finally have somewhat of a tune on my car. The clutch is holding fine as i can smoke the tires at 70 mph. We'll see how things go from here.
The dowels should not under any circumstance just come out of the flywheel. The dowel that came out of my flywheel was from my p/p coming loose. How long did you have the clutch? Good luck with it.

but the scratches do concern me, like if the material is giving out and is softer than the disk 
. The last thing I noticed is that the pedal was kind of stiff when first installed and then towards the last week of driving it "by the way this is just a weekend driver, I drove it those two weeks to break in the clutch and have it tuned" the pedal started to get softer, but every once in a while it would feel stiffer/harder but still would not let me ingage it into gear.I'm glad to see that everything worked out for you, I wish mine was running the weather has been great for superchargers
here in Calif. I haven't even had a chance to see what this thing can do since then Last edited by 1RADWS6; 12-21-2005 at 04:06 PM.

I have the exact same problem.. Really hard to get into gear at RPM and stubborn to get in reverse. It does not feel like its loosing pedal pressure but it does engage right off the floor. I have all new Hydros as well. I even went with the Ram Adj master to see if it would help and adjusted fully out it still engages off the floor. I have bled the system every which way, incl mity vac with no change. Clutch was great for 400 miles and now it is acting messed up. I did use locktight on all the bolts, torqued them in the proper sequence and to the proper value and now its acting up 400 miles later. Well looks like im going to have to pull the *** out of the vette again. Anyone have any ideas before I do it and is Textralia easy to deal with when it comes to warrantys? This sucks

This is irrelevent if a loose pressure plate was the problem, but FYI: one of the common things to do during a tune is turn off Catalyst Overtemp Protection (richer mixture used to cool the cat anytime the PCM calculates that it might get too hot). The clutch line passes close to the cat for a good chunk of it's length, so it IS plausible that tuning could cause clutch problems.
