there are over 500 posts at this website about the 2012 automatic transmission problems
if you do a search for 2012 transmission problem here you'll find them.
no matter what the dealer or Ford tells you, it is NOT normal for this type of automatic to have a pronounced hestitation/shudder to the degree that your passengers ask what is wrong.
I owned a VW GTI with this type transmission and the hestitation/shudder was nowhere near this bad.
Mine got dramatically better when the new england weather turned colder. If it was normal, why would cold weather make it go away?
You need to read as many posts as you can and become your own advocate. Learn what TSB's have already been issued.
There are a few people where the transmission had to be taken out, seals replaced etc before the problem was finally rectified.
