What is the hose that runs of the top of a t56 transmission and is the clutch cable or hydraulic.

I'm in the process of researching everything I'll need to swap the car. I am not an expert so my next question is does the vent line hook up to anything? The one after that is with it being hydraulic is all the hydraulic stuff inside the transmission or some other part like the bell housing or do I have to go buy a master and slave cylinder for it separately. Thank you for answering my previous question.Originally Posted by Twin_Turbo

Edit** I don't know much about hydraulic clutches and transmissions and the way they work so sorry if I sound dumb

The vent line hooks up to the atmosphere.
The clutch hydraulic system works EXACTLY like brakes, except that instead of the fluid pressing on brake pads, it presses on the clutch fork. It is entirely external to the transmission. There is no "hydraulic stuff inside the transmission". The master cylinder bolts to the firewall, and the driver's foot presses on it; it pressurizes the fluid, sending the pressing effort down the line to the slave cylinder; the slave bolts to the bell housing, and it presses on the clutch fork. No-brainer.
Easiest way to get it is, or at least used to be, to just go to GM and buy the entire assembly pre-assembled, filled with fluid, sealed, and bled. Master cyl, line, slave cyl, reservoir, and cap.
Talking about the LT1 version of it here. The LS version is different: it doesn't use a fork like the LT1 version does, instead the slave cyl and throwout bearing are integrated, such that the slave cyl presses directly on the throwout. Exactly the same except completely different.

Thank you that clears this up a lot for me.Originally Posted by sofakingdom

Could you link it for me so I don't get the wrong thing?
It would be greatly appreciated.
