THE TPS HAS BEEN REPLACED TWICE, ALL LEADS FROM THE WIRING HARNESS HAVE BEEN GROUND AND LUBRICATED, BUT THE TRANSMISSION SHIFT SHOCK REMAINS. THE MANUFACTURER'S TECHNICAL DEPARTMENT, HAVING MADE THE FORMER GUESSES ON THE TPS REPLACEMENT AND LEADS, SUGGESTS REPLACING THE ECM AND TCM TO SEE IF THAT CORRECTS THE PROBLEM. THE SEVERE SHIFT SHOCK IS THE MOST CURRENT PROBLEM WITH THIS EGREGIOUSLY DEFECTIVE VEHICLE IN WHICH ALL MAJOR PARTS HAVE BEEN REPLACED SINCE PURCHASING IT NEW, THE REPAIR COST SO FAR EQUIVALENT TO THE PURCHASE PRICE. THERE IS 126,000 MILES ON THE ODOMETER AND THIS VEHICLE HAS HAD ONLY ONE OWNER WHO HAS ALWAYS DRIVEN IT WITH THE UTMOST CARE. THE VEHICLE IN ITS CURRENT STATE SINCE JULY 2010 IS DANGEROUS TO DRIVE - WITHOUT FOLLOWING AN OBVIOUS PATTERN, THE AT DASHBOARD LIGHT FLASHES AND WITHIN SECONDS THERE IS SEVERE SHIFT SHOCK, ON HIGHWAYS AT 65MPH AND IN CONGESTED TRAFFIC AT 10MPH. THE ENGINE HAS TO BE TURNED OFF IMMEDIATELY SO THAT THE COMPUTER COMPONENTS CAN HOPEFULLY RESET, WHICH RESETTING DOES NOT ALWAYS HAPPEN. IF THE ENGINE IS NOT SWITCHED OFF, THE SEVERE SHIFT SHOCK CONTINUES. HAVING THIS HAPPEN AT ANY SPEED IS SO DANGEROUS, AND TRYING TO PULL OFF TO THE SIDE OF THE HIGHWAY IS EVEN MORE DANGEROUS. THERE ARE HUNDREDS OF COMPLAINTS ON THE INTERNET FROM SUBARU OWNERS, BUT SUBARU CORPORATE OFFICE DENIES ALL RESPONSIBILITY, SIMPLY STATING THAT THE VEHICLES SHOULD BE TAKEN TO DEALERSHIPS. THE DEALERSHIPS ARE UNABLE TO FIX THE PROBLEM AS THE DEFECT IS INHERENT IN THE MANUFACTURE OF THE VEHICLE. *TR
