1991 100q difficulty shifting

[laraa at sympatico.ca]

My second thought is for a worn pressure plate or release bearing or a slave
cylinder out of adjustment. Clutch doesn't disengage fully, main shaft is
still spinning a bit, 1st gear synchro does its job by attempting to slow it
down (hence the resistance). Other gears are easier since the speed
differential is less. 

You can test the behavior by leaving the trans in neutral, and try to shift
into second or third from there. If resistance (less than in first, but
still), my bet is on the clutch. Shut the engine, do the same : if no
resistance in first, (except for the gear meshing together), it would point
to the clutch. 

Anyone can destroy my theory ?

My first thought is worn synchros.  When you shift quickly both shafts are
spinning. When you go to neutral, one spins down.
