NHTSA Complaint #11282272 — 2003 NISSAN SENTRA

I WAS DRIVING AND THE CAR SHIFTED ITSELF FROM A LOW GEAR TO A VERY HIGH GEAR, LEAVING ME WITH NO TORQUE. THE NEXT GEAR WOULDNT LOCK-IN UNTIL RPMS HIT REDLINE, AND EVEN THEN IT WOULD FEEL LIKE ITS SLIPPING, OR MAYBE ITS IN OVERDRIVE GEAR(4TH) WHEN IT SHOULD BE IN 3RD.. AND ALSO THE TRANSMISSION WOULD NOT SHIFT DOWN UNTIL I CAME TO A COMPLETE STOP... THIS IS VERY DANGEROUS WHEN YOURE ON THE FREEWAY, BECAUSE THE CAR WILL ONLY MOVE 40 MPH. AND ALSO DANGEROUS WHEN CLIMBING HILLS/FREEWAY OVERPASS, BECAUSE THERES NO TORQUE TO GET UP THE HILL, AND THE TRANSMISSION WONT PUT ITSELF IN LOW GEAR UNTIL YOU COME TO A COMPLETE STOP... I THINK ITS AN ELECTRICAL ISSUE BECAUSE IT HAPPENED SUDDENLY... IF IT WAS MECHANICAL, I WOULDVE FELT IT SLIPPING GRADUALLY, AND IT NEVER SLIPS. I JUST DROVE IT A COUPLE DAYS BEFORE TO THE BAY AREA AND IT CLIMBED THE HILLS SMOOTHLY, NO PROBLEM.. I HAVE NO CHECK ENGINE LIGHT, SO IDK WHAT THE PROBLEM COULD BE...
