[Shotimes] O/D Light on ATX

[Jason Hartberger]

This is most commonly attributed to the O/D button on the gear shifter
itself. The button contact wears out and can send false positives/negatives.
I know there's a procedure to replace the button, but unfortunately I
believe it involves putting a new shifter in. There might be another way to
fix it, but that's what I'd concentrate on first, the shifter knob.
