The cause of the accident was due to an extremely hard downshift, then extremely hard upshift. Between the speeds of 25-37 mph the truck will do a hard downshift with a 1-3 second loss of power delay. When it finally grabs gear it takes off like a rocket before grabbing the next gear and back to what feels normal. This is something I never experienced in my 2022 Ford F150 with the same motor and transmission. This particular day, I had pulled off to the side of the road to let the mail carrier go through the narrow section of the road first. This particular section, there is a huge tree right next to the road (approximately 12"-14" off the road). After the mail carrier passed, I started to speed up. Upon hitting 34 mph, the transmission shifted hard, pulled me into the ditch, and by the time the gear grabbed, and I had power to control, I hit the tree. As a habit, since this issue happened numerous times, I looked at the speedometer and just prior to impact I was at 43 mph. The transmission is not the only issue that I have been having with this vehicle. There has been a fuel consumption issue, a hard start issue (does not matter time of day), as well as a grinding issue at the front right wheel. This truck is equipped with a 36-gallon fuel tank. At the city driving mpg and a 34-gallon fill-up, I should have been getting 544 miles/tank. However, that was not the case as I was only getting 440-447 miles/tank (did not matter whether normal, eco, or sport mode driving). Each fil
