My big bear 4X4 year 1996 (2)

My big bear 4X4 year 1996, I tried to change gears, it still remains in the 4th either before or back and the splines of the shifter are not stripped on the shaft it goes up and down but the others speed do not enter, can it be the fork or the gears or something else. You know what it depends


thank you for your answers :smile2:
