Transmission searching
I have had my ecoboost for about 2 months now and it seems like the transmission is searching for the right gear a little to often. It mostly happens when im using cruise control and going up or down hill....anybody else notice this???

What rear end do you have? I have not noticed this in mine. I thought my ten did this and my 11 was much better. However my 10 never made the hard 1-2 shift or the 2-1. I thought I was just lucky and not having the issues others have posted. Not the case with the 11. To my surprise I'm getting the hard clunk from time to time. Hopefully will not continue because I absolutely love the truck. I have the 3:73 rear in the 11 EB. And I had the 3:55 LS in the 10.

My ecoboost with 3.73's stays in 6th very well. I did notice in cruise and going downhill if your speed gets too high over the setting, the transmission downshifts to give you compression braking to check your speed. It doesn't use any more fuel as the fuel shut off feature is active when off the throttle.

with active learning these trans seem to be like toddlers learning to walk. My eco is not to bad but my 11 superduty was terrible for the first 5k. It would shift back and forth like someone learning how to drive a stick. Dealership told me to drive it hard for a few days and it seemed to clear up the shift confusion.

My old Duramax would shift hard if I didn't drive it like I normally would.. If the Ecoboost transmission is as smart as that allison was then it may be the same issue with the hard shifts.

I'm glad I'm not the only one with transmission questions my 2011 5.0L has some odd transmission issues that I've never had in a Ford Truck. One of the oddest things is that it shifts from 1st to 4th gear very quick. It's in 4th gear in city traffic at 30 mph......not good when traffic starts moving faster... it bogs down for what seems like forever before it down shifts to start moving in the correct gear.
