Looking for some insight into the following issue:

2006 Mitsubishi Exclipse 4cyl 5psd.

Car was purchased safetied with a slight noise that sounded like a throw out bearing.  Car drive fine, no slipping in the clutch.

We took the transmission out and had our mechanic look at it, turned out to be the input shaft bearing, got it replaced, put the transmission back in the car.  Nothing. Car will not move. 
You can hear and feel the transmission shift into the gear, but the car does not move, also has a slight grind like noise that sounds like the splines on the output shafts aren't grabbing or aligned properly. 
Also another weird issue is with the clutch, we bled the system and can visually see the clutch fork moving, but it feels like it doesnt disengage the transmission from the engine when pushed.

The transmission was pulled again and had two other people look at it and said it was fine.

There's not a whole lot of information I can find anywhere online so all input is appreciated.

    so with the trans on the bench, can you manually shift it into each gear and when in each gear while turning the input shaft the diff/output shaft turns in relation to it?

      When you say it doesn't move, what does that mean exactly?  You said it goes into gear fine?  Then you let out the clutch and it doesn't stall, but doesn't move the car, or what?  Need a better description of the issue.  Does it affect the revs at all when you let out the clutch?  You say you've had it back out of the car again, did you confirm the friction disc was properly engaged on the output shaft?  I can't see how it would ever go back together if it wasn't, but this is a strange situation.

      Are you sure the axles are properly engaged in the diff when you have it all back together?  If one side wasn't, the open diff would try and send all power to that wheel, which could explain what you're seeing.  Just a shot in the dark.

        As @IanB  said, with the c/v not engaged correctly it can cause this. Or I diagnosed myself a clutch disc installed incorrectly, with the face (the protruding side of the disc) installed towards the flywheel. Was the clutch disk installed in the proper direction?
