Went to start up my car other day, let it warm up for 15 minutes before driving it. So I reverse out fine, put it into drive, and it acts as if it is in neutral in drive. I was able to drive it to transmission shop this morning by using tap shift but gears 1-3 were slipping bad along with vibrations. My guess is something internal in the trans. No codes were present. Fluid level has been checked and looks normal with no odd smell. Car is still under warranty, hoping it will be covered if tranny has to get rebuilt.
