I, too, had many problems with my 2012 Focus transmission. I had an update done twice but still didn't shift right and it had a bad "shudder". Well, it is finally fixed!!!!! There was something leaking that when the leaked fluid got on something (I'm a girl, I don't know all these parts) it caused the shudder. They fixed that and now the transmission is about 99% better, too.
Also, all 4 of my windows are one touch up&down to the surprise of everyone at my dealership. Does anyone else have these?
