I guess I'll do one that at a time, do the slave then the master.

Ok, I just got done with the master cylinder. I had already done the slave cylinder, pressed the pedal in, cranked the starter in gear, car lurched. So I finished installing and bleeding the master tonight. Put the car in gear, push clutch in, crank starter, and the car still lurched.



What am I doing wrong? I'm pretty sure that if the clutch itself wore out, it would be gradual, right? This was sudden, like one shift was fine, then stopped working. So I'm still hoping it's not the clutch itself, or anyting that's expensive and involves removing the tranny.

Get under the dash, and start adjusting the rod.

Sounds to me like the fork fell of the throwout bearing. If you can see the slave cylinder pushing the rod out then that part of the system is probably working right.

can you see the piston on the slave pivot the clutch fork? if so the problem lies within the bellhousing.

Yes, but I'm not sure if it's moving the whole distance it needs to, I have yet to bother with the pedal adjustment.

Took the slack out of the pedal, and it acted weird. I would start it in first, it would lurch. Then I'd try again, it would start and idle in first, but if I tried shifting into neutral then any other gear, it would grind. I guess I have to remove the tranny no matter what at this point. Any idea what I should be looking for when I do this?

I removed the transmission. I think I found my problem. The bearing in the bellhousing that the fork pushes (is that the throw out bearing?), it has 2 tabs on it that look like they should hook around the ends of the fork. One tab is gone, broken off. I'd post pics but my cam went dead.



When I lowered the tranny, oil started coming out of the end where the driveshaft came out of. Is this ok? (assuming I put oil back in it) I wasn't sure if there was supposed to be some kind of seal or something there.

Yes, that is the TOB, and it's completely fine for the oil to come out the back of the tranny, it seals when the driveshaft is installed.

Baldy 01-15-2006 08:21 PM

Awesome. Isn't it nice to know what's wrong? Hopefully the dealership is open tomorrow (since I have the day off), and hopefully they have the TOB in stock. I guess the hard part will be getting the tranny back up there by myself.
