Get it so it reads right.....you may need a lower gear sometime in your 4R100 tranny and it will not go in. Pull the cover down on the bottom of the column. If the shifter is loose....there are 2 Torx screws(one on each side of the column)...they are way up in there but those need to be tightened. Next....you will see a little black wheel on the right side.....I have usually blocked wheels...put in neutral and turn the wheel till it is in the middle if "N".... check out all other gear positions and adjust if need be. Usually only takes about 10 minutes to do this.
