The transmission suffers erratic shifting normally between 3rd to 5th, and 9th to 10th gears where it feels as if the transmission goes into neutral when upshifting or downshifting between these gears. But, one issue occurred which has concerned me. After stopping at an intersection, when it was safe to proceed, I moved my foot from the brake to the gas pedal to proceed. The engine revved to higher RPM's, but the truck did not move as if it was in neutral instead of gear. As I looked down at the tachometer, the truck suddenly locked into gear causing the tires to chirp and the truck then lunged forward through the intersection. This was a T intersection where you have to turn right or left. This incident was so harsh and unexpected, it threw me back into my seat. I was able to maintain control and make my turn to the left without going off the end of the road. This incident has not happened again, but the erratic shifting continues.

Before the v8 gasoline engine reaches some prescribed operating temperature ( before the engine is fully warmed up ), when headed downhill, no low gears function in any mode and the engine experiences sudden unintended acceleration. The truck was purchased new in 2018. The ford company has repeatedly acknowledged the defects, and however claims that all 2018 gasoline powered f250s are designed that way to meet certain standards and therefore everything is fine despite being extremely dangerous in certain circumstances.
