We did something like that yesterday. Lifted the rear and started the car in first. Clutch isnt fully engaging because wheels kept spinning even clutch was pushed down. Today I took off the metal piece from under the tranny and looked inside as a buddie depressed the clutch pedal. The pressure plate only backs off from it alittle (not fully releasing the clutch from what I think). The torqueing I did probably wasnt right. So if I were to tighten it, would the pressure plate back off more as Id push down the slutch pedal or should I loose the bolts alittle?

 

The pressure plate should be fully mounted to the flywheel, then tourqued to 18 ft/lbs.

 

yeah I know. I was just being a dumb *** when I was putting it on. I think that I over tighten it the first time. Its guess and check for me now.

 

Just to double check, you did get a TII slave cylinder correct?

 

did you verify that the clutch fork was in good condition?

sounds like a possibility that has been overlooked.

 

Yes I checked. I found the slave that came with the tranny and compared it with then new one I got. Same thing except for the rod so I switched those.

 

I did just look at it and greased it up when the tranny was out but I dont know how it acts/looks like when its a bad fork. Of course when it was out, I pushed it the way the rod would just to see how far itd go. Itd seemed ok to me. But that is a possibility

 

Try this for the hell of it.With the car up on stands..You already know when you press the clutch Pedal in that the clutch only engages so much./.Have you tried to Move the clutch fork back Manually and see if the Clutch engages Fully that way?..If that is so,then the problem would lie in the Hydraulics of the Clutch system and not Inside where the PP and clutch are.(thinking..Again!..that the Clutch hydraulics are Not allowing the Slave to push the clutch fork back ALL the way,and therefore your clutch is not Working to it's Full potential.)

 

That was my thought exactly. I extended the push rod on the clutch pedal to the full extent. Pushing the fork manualy is pretty hard but forsure we will try our best.

 

^Yep, that sounds like a good plan.

I highly doubt your transmission is toast.. it's probably something small that just slipped your mind during the install.

the problem with the clutch fork is that, unless it completely busts, it can be very hard to blame it for the trouble.

one time I had a clutch fork bend just enough to make sure that the clutch wouldn't engage.. I did what you did in the process of figuring out what was wrong, replaced pretty much everything I could until I finally realized under close analysis that the fork was actually bent.

just food for thought--it's a more common problem in cars making lots of power, but it could theoretically happen to anyone.

best of luck, my man.

 

even if the clutch wasnt working fully you should still be able to shift with the car off I helped my mechanic fix a shifter problem last thursday. The client bought an aftermarket shifter that didnt fit correctly because it was longer. So we cut it down into three pieces and welded it back into angles that allowed t to fit. So check the shifter with the covers off to see if its binding anywhere.

Its a good thing you found out about your clutch though. Dont wanna see on the news "Car modding gone bad".

 

Yeah it a big step by step process on finding whats wrong but thanks for the encouragement. The car can still shift while the car is off. All in all though, I think Im just going to take it to a shop and have them do the rest. Probably cost couple hundred but the 7 is worth it.

 

Yeah I think it's $300 or so to do an entire clutch job (not including parts). I saw a friend spend every evening for weeks replacing his clutch, only to get some kind of bearing noise afterwards. After that I don't plan on touching my clutch when it's time to replace it, heh.

 

Yeah thats what Ive benn doing. I think its a hydro issue thats easy to fix but not forsure so Im taking it in.

 

Hey all I have a question. I have a 86 gxl manual and I will be completely honest it was a rainy day and I took the car out for a while. I was about to burn out and all of a sudden the car wouldnt move. Parts of the U joints came out and everything. I know I have to replace that but I want to know why I cant shift anymore could it be a possibility that becasue of my drive shaft problem I cant shift or is it a transmission problem. Thank you and I would appreciate any answers.

 

What would happen if you have a turbo tranny and a n/a slave installed? What problems would occur?

 

The throwout bearing would exert force on the pressure plate at rest and lose clamping force.
