Problem is it transmission or computer?
 

My 2012 f 150 super cab 6 speed auto, 3.5 eco, 4 wd is starting to act up 75000 miles, this is very random but seems like its happening more, when I take off from stop light it wont shift out of low, untill i get pulled over shut off truck and restart, no rhyme or reason when its going to happen but does seem to occur more hence the post. It shifts fine every where else doent shift rough I have had a transmission flush thinking it might be oil getting bad, bought truck 2 years ago no problems first year just replaced water pump and brakes

Not sure where to start hate to take it to ford right away only other problem is lights wont shut off automatically have to shut off by hand seems like the timer quit

Hope I have provided enough to make sense, also when this happens the Tac & Speedo freeze and the display gets all garbled

did flushing the transmission do any good?
could be a lead frame issue

take it to ford... sounds like a possible lead frame going bad

That's my first thought also.

It slowed down after flushing. It used to do it about once a month
 

Lead frame is bad
 

Isn't this work covered by Ford program 16N02 if conditions are met?
