NHTSA Complaint #10503512 — 2008 FORD TAURUS

WHEN AMBIENT TEMP IS BELOW 20 DEGREES, HARSH 2-1 DOWNSHIFT WITH IMPACT AFTER STOPPING AND RESTARTING. THE TRANSMISSION DOESN'T SEEM TO BE IN ANY GEAR UNTIL MOVEMENT STARTS THENNA HIGH IMPACT BANG OCCURS JUST AS THE CAR BEGINS TO MOVE. AFTER ABOUT 1 MILE, THE PROBLEM GOES AWAY UNTIL NEXT COLD START UP. FORD DEALER STATED THEY REPLACED VALVE BODY BECAUSE OF STICKY VALVES. PROBLEM STILL THERE. RETURNED TO DEALER AND THEY CONTACTED FORD. FORD SERVICE TECH(FORD SERVICE REQUEST #106142903) SAYS PROBLEM IS NORMAL. THIS PROBLEM NEVER OCCURRED THE LAST 2 WINTERS I HAVE HAD THE CAR AND FORD LOANER CAR I HAD WHILE THEY WORKED ON MY CAR DID NOT HAVE THIS HARSH DOWNSHIFT. THIS TRANSMISSION IS A JOINT DEVELOPMENT WITH GM AND I KNOW A BUICK OWNER WITH SIMILAR COMPLAINT AND BUICK COULD NOT REPAIR THE PROBLEM-HE TRADED CARS. WARRANTY WILL END FOR MY CAR THIS COMING JULY AND I THINK I WILL HAVE A HUGE REPAIR TO BE MADE ON THIS TRANSMISSION NEXT WINTER AS THE PROBLEM HAS GOTTEN STEADILY WORST SINCE LAST FALL (2012 WINTER SEASON) BUT ONLY WHEN TEMP IS 20 DEGREES OR COLDER. PLEASE INFORM FORD OF THIS COMPLAINT. I WOULD LIKE A REPAIR OR EXTEND MY WARRANTY TO FEB 1, 2014 TO COVER MY COMPLAINT-THANK YOU *TR
