Well, no one seems to be able to fix it. This car was a gift from a veteran organization. The company whom gave it to us said they can't fix the problem. So when I drive to work 45 minutes away, driving speed limit between 65 to 75 mph, the car slows down to 60 then my rpms blow up to 5k. This almost put me and my family in a major wreck. I hate this car to the point of just sending it to the junk yard, but it's my only car. So I can't, I just got to keep driving it, until Nissan will fix the transmission due to factory defect or I eventually get ran over by a truck or even hit by a train cause it eventually stops working and won't move.
