After a rough shift from park into drive the car isn't shifting into overdrive at speed. It runs through the four gears and then won't get itself into overdrive. I noticed that the lettering in the dash board in now reversed from how it normally looks. The letters and now Framed in black, the opposite of how it used to look. I need help quickly, I am on the road as you read this from NJ to NV....long way. It's as if it's in a safe mode of some kind....please help.
