Take your other foot out from under the pedal?


Anything odd happen the last time you drove it? With the car off can you put it in gear? if in gear and you try to start it does it move?

I haven't drove it yet, I bought it like that, I can't put it in gear with the car on or off.

Sounds like a catrosopic failure, Clutch disk came apart or the trans did.

So does that mean that I need a new trans?, I have another 12a and 5- speed in my parts car so that would not be a problem. You don't think it could be a slave cylinder?

Well, that's the 1st time i've seen this. I would have to say their are several possibilities.
1). The trans input shaft came apart and cracked the front cover on the trans where the T/O bearing rides on and now the bearing will not slide back and forth.
2). The disc came apart and wedged inbetween the pressure plate and will not allow the fork to move.
It all means that the trans needs to come out and see what happened. Take pics please, this i have to see,lol.

It could be the slave and that is where I would start, but you should be able to put it in gear when off without using the clutch.

You might need a slave when you get done, but it is not the cause of your initial problem.
With the engine off, if you cannot shift the trans then it is an internal problem, Ie: Trans.

When I bought the car the clutch pedal was on the floor, so I pulled it up, and since then I can't push it in.

Damn Newbies

If you cannot depress the pedal which means no matter how hard you press on the pedal
it will not go down, Meaning it is stuck? Did i get that portion correct?

The slave or master are just hydraulic pushers of fluid. The slave being the one that pushes against the Fork to disengage the clutch. The only thing to stop the pedal from going down is
something binding against the fork. Which means T/O bearing, pressure plate, etc..

The frikin story changes everytime i repost

If the clutch pedal was on the floor and you pulled it up and now it is stuck and the pedal will not move then i would start at the clutch master cylinder. Sounds like the piston is hanging up probably because of rust. you will probably wind up changing both the slave and the master.

If the master is rusty, it will cause this problem.

The guy I bought it from said it had been sitting for a while so it prob is rusted, but thats the only thing wrong with it, except he deleted the rats nest and it got a vacum problem (if it goes below 2000rpms it will cut off). Would someone know how to fit that? I got the write up on the delete. Should I just go threw that and do what he didn't do right? But I only paid $200 for the car, engine only has about 50k miles, don't know about the trans.
