Recently had 4 instances of shifting from 10th to around 5th running at 80. Very concerning as it felt like i was leaving the transmission on the highway. Took the truck into the Ford dealer and the tech could not replicate the problem. They agreed to install a computer that was hooked to a handle with a button that I depress and it records for a period of 30 seconds. Took the truck home (1 hour drive) and it occurred twice at around 85 mph. I hit the record button as it occurred. Now truck is back into the dealer and hoping to hear what they pull from the recorder. Anyone with a similar problem?
