Is there a separate switch that controls these functions? I would expect if the park light was on the unit would not shift to any other gear? Appreciate any thoughts.
Sounds like your nason switch

It's on the air brake parking plunger. It's common for those to fail.
If you replace it yourself, be sure you bleed all air off before taking switch off.
