HELP ME TRANNY!

I was driving down the highway in 5th gear after a long rebuild of my engine... and i went to shift down into 4th to get the RPM's moving a little bit to break in the engine and i couldnt get it into 4th so i went back to 5th and it was fine for a minute and then sliped a little bit went back and then like 30 seconds later i hit the gas and just reved up no noise no nohting just went right there. i thank god i was near an exit i got off and went through the gears i had no 1st 2nd 3rd 5th and reverse. 4th was very hard to get into gear but it went so my brother drove it back from torrington Ct to waterbury CT with 4th gear soemhow made it to my house i figured it wouldnt really mess up much more than what already was... exce[t my new clutch. anyone have this happen? anyone know if its going to be soemthing i can rebuild or just buy new.. when i get it apart ill try to get soem pics. thanks bye
