Thanks YT90SC, the lack of sufficient time paid to the tech is the main reason I suggested it's flawed, though your point about not trusting their factory techs also wasn't completely lost on me. I did a lousy job of saying that by only mentioning how our shudder has always been much worse when the vehicle's hot, which isn't unique to our car. I also should have skipped any comment on the dealer's work, because I have no reason to believe nothing was done the couple of times we had it in for other reasons and I asked them to check it based on 14M01.
I'm really just annoyed by this latest development. What knuckleheads would try to quietly offer a pseusdo-extended warranty for one week with no advance notice. I don't win lottos, and this was no exception. Just adds insult to injury for someone like me that has tried to patiently wait out a solution while living with the limitations. It's the wife's car and she still likes it, even if the TCM did scare the hell out of her on the expressway the day before it took a complete dump. And all in all, at 110k with one TCM, one seal replacement and cleaning (yeah, it was done early), I don't think it's been as bad as some make it out to be.
On a personal note, I sure hope you're appreciated at your dealership. What sounds like a high level of competence and commitment makes you one valuable "asset".
