1985 hiace column change 5speed stuck in gear in even in nuetral

Hi group, 

We have the above van. While driving, it started to play up while changing gears. Eventually I couldn't select any other gear position that would let me drive apart from 1st gear position. Now while parked with or with out using clutch I cant select 2nd gear position. I can select 1st position which lets me drive forward. 3rd,4th,5th and reverse and even nuetral I can select, but these positions all just stall the vehicle with no movement at all with or with out the clutch.

Any ideas and input much appreciated.

Pete
