I (and many others) have been posting transmission issues in the non-performance section of 2012 Focus (whoops!)

Here's an update on that pulled TSB:

For these DTCs, the technical details probably aren't important because there is a TSB that covers these issues:

TSB 11-10-2
Publication Date: October 2, 2011

Some 2012 Focus vehicles built on or before 8/12/2011 may exhibit the following engine drivability and/or automatic transmission concerns; RPM flare on deceleration coming to a stop, rough idle on deceleration coming to a stop, intermittent engine idle fluctuations at a stop, intermittent vehicle speed control inoperative, intermittent harsh engagement/shift, engine no-start with engine coolant temperature (ECT) open circuit faults and intermittent no-crank/no-start condition after performing normal Powertrain Control/Emissions Diagnosis (PC/ED) pinpoint test (PPT) diagnostic procedures. The vehicle may also exhibit diagnostic trouble codes (DTC) U0422, P00D2, P068A, P0850, P2610, P2832, P286F or P2877. The vehicle may also exhibit intermittent false initialization to 21 C (70 F) on the instrument cluster's ambient temperature display upon engine start up.


The fix is a simple reprogramming of the PCM and TCM.
Not that it seems to matter, because my dealer told me "That's how these transmissions work."

That's how they work - but they've changed something on models after 8/12/2011 and won't tell us what or why? I guess I didn't know dual-clutch transmissions were supposed to make crunching noises when shifting gears... I'm just trying to save Ford (and myself) a headache and $$ when my transmission fails in 3 years due to bad programming and the warranty will have to pay for it.

Btw, I'm at 7,500 miles and will be checking this issue at a different dealer tomorrow.
