Either that or a bent shift fork/rail would be my next guess if its internal. Make sure nothing is interfearing with your shifter linkages first then start to look for other things internal.

Mo is right. A synchro doesn't do anything to keep the tranny in gear, it just makes it easier to go into gear. Never seen or heard of a shift rail or synchro twisting. Input shaft doesn't have anything to do with shifting. The 2 gear faces are probably just wore down and don't have enough contact surface anymore and are popping out. Either that or the shifter linkages are not adjusted correctly or the cables are loose.
