I have a F350 4 x 4, 5.4L, I am having an issue when I am driving anywhere from 40 to 75, it feels like someone going 100 miles per hour rams right into the back of my truck then it seems as if the gear gets stuck, it causes me whiplash almost and also my tires screech. Then I have to pull over and turn off vehicle for it to kind of reset it self. Does it happen all the time no. Is it happening more frequently, yes. The code that was flashing was for a solenoid sensor so that was replaced. Can you give some sort of direction. After code was fixed we thought issue was fixed and no still did same thing, and the truck is NOT giving one single code. please help. Thank you
