Is your Focus still shifting smooth? I just got the "service your transmission now" warning also. Took it to the dealer. Picked it up and all they did was "updated PCM/TCM to most recent calibration"My 2012 Focus SEL gave me the "Service your transmission now" warning on the weekend (about 60,000 miles). Worked very well up until then. Drove it to the dealer Monday morning, S mode didn't work and the shifts occurred at about 3400 RPM.
Dealer replaced the TCM and had the car back the same day and the shifts are now smoother than before.
I complained about getting another bandaid. They said it was all good and until it wasn't that was all they could do. 3 hours later they called me and said they just found a bulletin on replacing the TCM. Supposed to take it back in the AM. Focus only has 32k miles
