The inlet tube that goes into the slave cylinder keeps leaking when I try to bleed the system. Is there support the be a rubber mount that goes inside of the slave slider where the inlet tube goes in ?

What do you mean by inlet tube ?

 

The tube that goes into the slave cylinder. But I found out why. It leaks. But my next problem is this.
My car won't go in to any gear.

 

Probably won't go into gear because your hydraulic system wasn't properly bled. Did you correctly bleed the clutch line until there were no more air bubbles ?
