hotleadsingerguy, you're a genius! Inconclusive for now (I have a long commute home later today to gather more "data"), but, I went out mid day for errands, and tried this (I have the shudder issue as well), and , it worked! Not a single shudder, stumble or hesitation at all. Very smooth starts from a standstill, and the shifts seemed "crisper" for sure. Just before I re parked the car for the day, I turned the TCS back on just to test this, and my last standing start into the parking lot produced the shudder right away...hmmmm, I think we may be onto something. I have the car booked in tomorrow for an oil change and they are looking into my DCT issues (may have a leaking seal inside the bell housing). I will mention this finding to them to see what they think.
What I find surprising (I guess maybe I shouldn't though), is how come none of the service guys or Ford engineers even once thought about this, since we all know that the latest TSB/FSA update changed the way the TCS/ABS system behaves ---- none of these field engineers looked into a possible connection? really??
Like you hotleadsingerguy, my shudder issues didn't start until after I had the last update applied (not by choice, the dealer did it anway)... it drove fine prior to that.
