The transmission in the vehicle does not match the life of an average vehicle, especially a modern one. Even with good maintenance and driving habits a transmission beginning to fail around 120,000 miles is absurd. With a failing transmission you have no idea what will happen on the road, when the gears slip and you beginning to max out RPMs and it trying to figure it self out, this could easily cause an accident or a fire under the hood putting everyone around you at risk and the warning lamp didnat appear until after the event . I have been quoted by the dealer for a total transmission replacement at around 12000 dollars which is well over half the value of the vehicle. I know that this has been a recurring issue with many F150s with this transmission and recall on this part needs to happen.
