Clutch will not engage or disengage

Okay let me explain myself. Now. I am a mechanic. Not a experience one. It I am becoming that. Now I replaced my clutch thinking that was the problem. But I soon discover that I blew my transmission. How do did I know that? Well when I went to drain gear oil. There was none! Just pieces of the transmission. Plus it only let me pull out in fourth! So I got another transmission put it in and put gear oil in it and everything. But! It will not go into gear while running. Now I have replaced my master cylinder and secondary/slave cylinder. So that is not a problem. I have even fixed the clutch pedal. It is supposed to be nine and a half inches from the floor. I have even bled it multiple times. With a vacuum pressure pump! I also got a air vacuum pump and used that. I bled it like crazy! I have no clue why my clutch is not disengaging or engaging. It feel and looks like I am not building enough pressure. Can someone help me? Give me an idea or anything!
