NHTSA Complaint #11365936 — 2005 FORD FIVE HUNDRED

TRANSMISSION HAS VERY HARD AND DELAYED UPSHIFT AND DOWNSHIFT MAKING IT DIFFICULT TO CONTROL SPEED WHEN ACCELERATING AND DECELERATING. RPM GETS STUCK AROUND 3000 AT LOWER SPEEDS AND UPON ENGAGING INTO GEAR HAS MADE MY TIRES SQUAWK WITH A SUDDEN LUNGE IN SPEED AND SAME PROBLEM WHEN TRYING TO STOP, THE CAR LUNGES FORWARD. IT ACTS AS THOUGH IT IS IN NEUTRAL BUT THEN WHEN IT ENGAGES INTO GEAR SUDDEN CHANGES IN SPEED OCCUR CAUSING RAPID ACCELERATION OR DECELERATION. THE PROBLEM GETS WORSE AFTER THE CAR IS UP TO NORMAL OPERATING TEMPERATURE. IT DOESN'T OCCUR AS OFTEN AT COLDER OPERATING TEMPERATURE. THIS PROBLEM MAKES IT DIFFICULT TO GET BACK UP TO SAFE HIGHWAY SPEEDS AFTER HAVING TO STOP FOR TRAFFIC OR RED LIGHTS AS WELL AS HARD TO GET UP TO SPEED TO SAFELY MERGE INTO TRAFFIC FROM AN ON RAMP. AS FAR AS "WHEN" THIS HAPPENED IT IS EVERY DAY AS I DRIVE DAILY.
