Blazer 99Lt automatic 4.3 with shift lever in floor.
Almost Everything works fine... But I can't put my lever on 1...it feels like it can't go so much further. Other positions works fine "PRND32". And indicating "red" thing near shifter doesn't show N and can't go to 1... But works on rest positions quite fine.
What could be wrong and what I should adjust to make it work properly?

When I put on 1 car moves but I hear ticking sound or something like clock :-) when is on 2 or any other gear everything works fine. Neutral and park also seems to be in right lever positions.
