I have 2010 sts v8 that did the same thing, all I did was reset the computer by unhooking the negative battery terminal for about 45mins-1hr (suppose to only take about 15mins but caddy’s are difficult)
Check your adjustment cable on the bottom ot the transmission if everything is ok then is your shifter box my car was doing the same thing i replace the whole shifter box problem solved
But as I stated before, Fight Klub put battle rap on the map, then Smack and the URL crew put battle rap on the map. Now Smack and the URL crew has taken battle rap to the highest point it can get you. PPV and/or havin its own Comcast channel is the next step. #RealShit
