I have a 2012 Fiesta SE with the dual clutch transmission. Can't seem to fix the issue with the code P07A3 Transmission Friction Element A Stuck On. Symptoms were stuttering, bucking, hesitation. Been to the dealer three times. Replaced clutch assembly and seals, then the transmission control module TCM and reflashed, then the clutch actuator motors. It has good grounding. Code still shows up and now it drives good about half the time and skips 3rd and 5th the rest of the time. Does this nearly every other start. Now I'm wondering if it may be a bad sensor or still the TCM. Any thoughts?
