Help - Adjusting ‘67 904 console floor shifter

All I know about automatics is that I wish my car was a 4spd.

Reading what I have available, I am starting to wonder if the problem is internal in the rebuilt transmission.

Could the valve body or rooster comb cause my problem? When I manually move the shifter on the trans, it clicks into the gears. 1, 2, and D and Park are solid clicks. Reverse and Neutral seem to be less solid. Is this normal?
