2012 ecoboost screw 4x4. Was going 60 mph with cruise on and had to accelerate a little bit to pass a car...got up to about 75 and it never downshifted (this was normal as I didn't press the go pedal very hard) as soon as i let off it slowed to about 70 mph and slammed down into 4th. It eventually got back into 6th. Going to dealer on monday as it was a pretty violent affair. anyone else have this happen to them?

Something very similar happen in my 2010 F-150 4.6 w/6 spd transmission "but", I wasn't cruising at 70 . My truck would shift sometimes "violently" when accelerating between 3rd and 4th gear. I take the truck to the dealer to only have them tell me that there's nothing wrong and that they did a stress test on transmission and checked out the transmission module. What I findout later is that when the tires are properly inflated (above 35 psi) the transmission shifts better then every before. P.S. Hope the dealer gives you a better answer then they gave me.
