The LED that makes up the "box" that surrounds "D" and "3" for the gear indicator no longer illuminates in the cluster.

I ran the diagnostics, and sure enough, these boxes do not turn on during the test.

If I replace the instrument cluster with a used one, the current mileage should display correctly with the replacement cluster, as this value is stored in the BCM. Is that correct?

I wouldn't bother fixing it, but my teenage son will be driving it soon, and I don't want to risk him having it in the wrong gear.

Thanks,
