Slave cylinder issues again after a new unit installed! Need help.
Alright so I installed a brand new Slave Cylinder yesterday and bled the system and had it working great again. Drove it to the end of the road last night and it was fine. But when I was driving to work today I got half way there and it started having problems again.
I pushed the pedal down and it suddenly felt like there was no pressure and it was engaging/disengaging right at the floor pretty much. Couple pumps later and it stuck to the floor. When I tried to work on it today after I work I discovered a problem with the shaft coming out of the back of the slave. Where it pushes against the transmission (not sure what the little part that sticks out of the tranny it actually pushes against is called.) I found that there is a hole in the middle of it. The shaft that comes out of the slave has pushed right through that hole. So I loosened the bleeder nipple and pushed the shaft back through the hole and got it setup so it was working again, closed the bleeder nipple, pumped the clutch pedal and had full pressure for about 10 pumps and then the shaft whent back through the hole again and no more working clutch.
Is there supposed to be a hole there? (hopefully someone understands where I mean).
And if so, do I have the wrong slave cyl or do I need to replace the piece on the tranny (if so what is its name and how?)?
Any help would be awesome.

I think you are talking about the fork on the tranny, yes there should be a hole there, but it shouldnt be large enough to allow the piston to go through.
You are going to have to pull the tranny and fix that fork.

There should be a little pin on the end of the shaft that fits in that hole. The end of the shaft should be much too big to go through the hole.

Two threads up right now with the same problem...
Also, you may need to adjust the pedal-to-master linkage under the dash when replacing the slave... I put a new one in recently, and had to make serious adjustment to get adequate throw after everything was bled out. I wonder if the newer slaves are a bit short in the rod?

hey
man i had the same problem. the shaft is in backwards. from looking online i thought the small end would stick out. do not put it in the hole, it will break seals and leak into your trans. exactly what happened to
mine i took it to a shop and theu told me. if it gets in your trans the brake fluid will start eating your clutch away. you most likely will have to have it taken to a shop put the slave on right replace the seals and drain The fluid out.

Yeah the shaft is backwards. I tried to remove it and it's almost the entire way out, but its stuck now. Didn't have much time to work on it the other day so going to try and do it this weekend. Thanks for all the help guys.

2 most common problems when doing this repair. 1. The push rod is installed backwards and can slip through the hole in the clutch fork. This is apparently what's happened with yours. Keep working at removing it, it will come out. Fat end of the rod goes to the clutch fork. I've made the same mistake myself. 2.The other most common problem is that by replacing only the master or slave, the other cylinder soon fails. That's why I recommend replacing both, along with the rubber hose as a single repair. Saves having to back and do most of the work all over again. If you don't replace the master now, be prepared to do so within a couple of months. Also recommend replacing the rubber hose with the stainless steel braided one. By doing the full repair/replacement, you shouldn't need to touch the clutch hydraulics for another 20 years, except for the occasional fluid change.

motor in pieces
It may not be the push rod on the slave at all, ive seen the bubble in the clutch fork that holds the push rod wear through completely. Make sure your clutch fork isnt shot.
