2009 FORD TAURUS Power Trainautomatic Transmission Problems

MY 2009 TAURUS LMTD AWD 6 SPEED 3.5 V6 WOULD ROLL BACK ON A HILL QUITE A BIT AND IF YOU PRESS THE GAS, IT STALLS AND YOU HAVE NO BRAKES. I BROUGHT THIS TO THE DEALER AND WAS TOLD "THIS IS A NORMAL CHARACTERISTIC. THE LOWER IDLE SPEED ON THE CAR DOES NOT OVERCOME THE TC SLIP UNDER THAT CONDITION. RECOMMENDED NO REPAIR ATTEMPTS BE MADE" I HAVE DOCS ON THIS. ANOTHER DEALER HAD THE SAME CAR AND IT DID THE SAME THING, BUT A 3RD FORD DEALER WAS MORE CONCERNED WHY IT STALLED. I WAS TOLD SO IT DID NOT HURT THE TRANSMISSION, (VERBALLY TOLD THIS). *TR

NEW 2010 FORD TAURUS SEL A FEW WEEKS OLD HAS A DANGEROUS DEFECT IN THE TRANSMISSION OR CLUTCH MECHANISM. THE PROBLEM OCCURS AFTER STOPPING IN TRAFFIC ON AN INCLINED STREET, WHEN TRAFFIC STARTS AND YOU LET OFF THE BRAKE TO MOVE YOUR FOOT THE ACCELERATOR, THE CAR FREELY ROLLS BACKWARDS TOWARD THE CAR BEHIND YOU BEFORE YOU CAN REASONABLY APPLY POWER WITH THE ACCELERATOR TO STOP THE ROLLING. THE TRANSMISSION IS IN DRIVE IN THE CIRCUMSTANCES DESCRIBED. THIS ALSO OCCURS WHEN PARALLEL PARKING AT A CURB WHERE THE STREET IS NOT LEVEL. THIS COULD RESULT IN SERIOUS INJURY TO SOMEONE WHO MIGHT WALK BEHIND THE CAR AT THE WRONG TIME. THE SECOND PROBLEM IS THAT AFTER THE CAR IS STOPPED ON AN UNLEVEL AREA AND PUT IN PARK, IT ROLLS FORWARD OR BACKWARD FOR ABOUT A FOOT OR SO BEFORE THE ENGINE TORQUE ENGAGES TO STOP THE VEHICLE. THIS AGAIN...
