Transmission shifted from 1st to forth and back down causing sudden stop barely avoiding a rear end collision with evasive maneuvers from other drivers. This condition repeated other times with no traffic. if I allowed it to continue and accident is eminent. I have taken the vehicle to a transmission shop for repairs. This condition is a manufacturing defect acknowledged by Ford and I am dumfounded why this agency has not required a recall for this dangerous condition. I guess you want to see someone die before you take action.
