Turns out P0571 (covers brake switch and cruise control) was the only thing that the dealer could find and/or duplicate a problem with. From what they told me, as well as what I've been able to glean from online sources and friends that wrench professionally, when the brake switch malfunctions it's as if you're driving two-footed. And potentially very heavy on the brake foot.
I don't drive two footed ever, so when the dealer kept asking if I did I was confused. At one point they explained that they see Chargers come in with this code somewhat frequently, because macho dudes are doing brake torques at stoplights before lighting 'em up. Clearly not something that's happening with the PM, but that's how it was presenting to the techs.
Thus my trans had been hot (I'm not sure if they used the word overheating or if I appended it after the conversation) as we came down the hill last weekend, not through any fault of driver but because this switch was malfunctioning. What tipped them off was when I said the cruise control wouldn't work, apparently.
Anyhow, they've since checked/repaired/replaced the switch and (according to the receipt) some associated wiring.
When I drove it off the dealer lot this AM I was tuned in (as always) to the shift feather that has been happening for months now. And it seems to be gone. I only got a few miles of running errands in, but never once detected the feather in that time. Thus maybe (so the dealer hopes) the brake switch has ben the culprit all along?
I'm hoping so too, but might just be past the point where my faith can be entirely restored in this particular van.
Heading out for a ~1000 mile trip on Monday morning. With fingers crossed, as usual.
