I'm posting this for my dad. He has a 1990 Vette. It’s an auto trans car but the shift light is lighting up on the dash which I'm guessing that should only happen on the manual trans? Any ideas what it could be? We haven’t starting any diagnostics yet, just trying to see if we can get someone to point us to a starting point
