TRANSMISSION IS HAVING PROBLEMS ACCELERATING AND SHIFTING GEARS. WOULD "REV" UP THEN NOT SHIFT AND NOT ALLOW MY CAR TO ACCELERATE WHILE I WAS ON THE HIGHWAY, CAUSING CARS TO BACK UP BEHIND ME AND PUTTING ME IN DANGER. AT OTHER TIMES IT WILL NOT ALLOW ME TO EVEN ACCELERATE. HAVE TO CONSISTENTLY RESTART MY CAR IN DANGEROUS PLACES ON THE ROAD TO GET IT TO EVENTUALLY WORK. WENT BY BODY SHOP AND TURNS OUT TO BE A SPEED SENSOR CODE ISSUE WITH THE TRANSMISSION. NEEDS SOME FORM OF A VALVE BODY REPAIR, BUT UNSURE TO WHAT EXTENT. THIS IS ONE OF MANY PROBLEMS WITH THIS VEHICLE. *TR
