The main shift rod (torque tube?) has splines on the end closest to the shifter. You need to get the trans in neutral and use the alignment pin (remove and reinsert the opposite pointed end) located on top of the trans to lock it in place. Under the car there is a bracket that the shifter slides on and a little hole on the bracket. Align the hole on the bracket with the center of the guide block on the shifter. The guide block should be held against the side of the bracket while you do this. It sounds like the splines are out of position and not allowing the shifter to rotate to get into the proper "gate". You can repostion the splines to get this back.
Or you can just remove and reposition the splines a little by "eyeballing it".
Hope that helps.
