Well, at least with it circled you know the issue, most cars are a guess, lol...
Being a Ford guy myself, I've delt with this issue before. The reason mine came out of adjustment is that the clip that holds the thumbwheel was broken. I just zip-tied it back and it's been fine for a while now. Below is how you adjust the Shift Indicator.
Cable Adjustment — Shift Indicator
1) Remove the upper instrument panel steering column cover.
2) Place the gearshift lever in the (D) position.
To verify you are in D -- (Rotate the gearshift lever clockwise until it bottoms out (first gear), then rotate two detents counterclockwise ((D) position).
3) Hang an eight pound weight on the gearshift lever.
4) Center the pointer in the middle of the (D) position.
- Rotate the thumbwheel located on the bottom of the steering column to adjust the pointer.
5) Remove the eight pound weight.
6) Carefully move the gearshift lever from detent to detent and compare with transmission settings. Readjust if necessary.
7) Install the upper instrument panel steering column cover.
Hope this helps ya out.
