NHTSA Complaint #10629276 — 2008 FORD EDGE

WHEN TRAVELING, ALL OF A SUDDEN THE SPEEDOMETER GOES TO 0, THE MAINTENANCE WRENCH LIGHTS UP AND WE GET AN LED MESSAGE THAT I CANT RECALL EXACTLY AT THE MOMENT. THE VEHICLE CAN CONTINUE UNTIL YOU STOP. THEN IT CANNOT PROCEED FORWARD. ONCE YOU STOP AND SHIFT TO PARK, THEN TRY TO PROCEED AGAIN, THERE IS A LOUD CLUNKING NOISE FROM THE TRANSMISSION, AND THE VEHICLE CANT MOVE FORWARD. I BELIEVE IT IS GETTING STUCK IN 5TH OR OVERDRIVE. WHEN A CODE READER IS ATTACHED BY A MECHANIC, THE CODE IT CALLS OUT IS FOR THE OUTPUT SPEED SENSOR (IN THE TRANSMISSION). ONCE THE CODE IS CLEARED THE VEHICLE CAN PERFORM NORMALLY. WE HAD THE OSS REPLACED BY A REPUTABLE TRANSMISSION SHOP, AND IT WAS FINE FOR A MONTH OR SO. NOW AGAIN WE HAVE SEEN THE PROBLEM TWICE SINCE REPLACING THE OSS. THERE SEEM TO BE MANY COMPLAINTS ON THE INTERNET REGARDING THIS EXACT PROBLEM. HERE IS AN EXAMPLE: HTTPS://WWW.YOUTUBE.COM/WATCH?V=PX3SC2YCMEO. *TR
