Clicking noise coming from slave cylinder T56

So I just installed my new pre-bled slave / master cylinder unit, the pedal feel is perfect but every once in awhile i hear a clicking sound coming from the slave cylinder, very soft. I'm not too worried about it but just wondering what this can be. I haven't driven the car yet since the install. I changed the slave / master per my earlier thread. Any idea what this noise could be?

You're positive it's coming from the slave? The clutch pedal switch click loudly sometimes, but I've never had the want/need to listen close to the slave. (I guess you have someone pushing the pedal while you're under the car listening with the motor off?)

I haven't gotten around to installing the safety switch yet, so I know it's not that. Plus I don't have the shifter boot on so it's pretty easy to tell it's coming from the slave. It doesn't do it every time though.

I don't know of any reason it would click.. How about the Reverse "lockout" solenoid? Is that hooked up to your clutch pedal?

Nope. When I bought the transmission 3 years ago, all the sensors were charred from being torched or something. I still have the old lock out in the trans but not hooked up yet. Keep in mind it shifted great up until the problem i was witnessing in the thread I posted above.

Re: Clicking noise coming from slave cylinder T56

Mine clicks occasionally too. I'm also curious to see what others have experienced. It clicks when I push the clutch in before I start the car, and no I don't have any of the safety switches either.
