The Expedition 6sp, 6R80 transmission is a BMW/ZF design, built under license by Ford. It has a adaptive learning module. It learns driving habits and shifts accordingly. The problem is, most people don't horse there vehicles, on a regular basis. That computer adjusts for a dull driving experience. Did you ever notice, how rental cars, have good acceleration? That is because they are constantly beat on. I have this frustrating transmission, in my 2011 Mustang GT. I wish there was a way to disable, this stupid feature and leave it in a performance mode, full time. I recently floored it around 20mph. The tires spun and it got a little sideways. It seemed to wake the car up, transmission wise. The shifting improved and now winds the gears out, slightly better. So if you have the 6R80, try opening it up, once in a while.
You think the 6R80 is bad wait till you drive the eight or ten speed... the most annoying vehicles you will EVER drive. It constantly changes gears and downshifts and any change in throttle position sends it hunting for gears. I'll say it does it subtlety but I notice and It makes me wanna pull my hair out.
