No shift indicator light?
the gear light will not highlight (PRND321-dash) when I shift. Also my check engine light come on today. My doors will not automatically unlock once I put it in PARK. They use to.
AutoZone read the codes and said it was a (aa1.-failed tranmission range sensor), and/or aa2.- Open circuit condition. How hard is that to replace or is it dealership time?
