They replaced the "module" again, which had already been done at 71k, nd 2 days and 70 miles later, the same thing is happening. There is a direct correlation between the car starting in 3rd gear, not downshifting to first when coming to a stop, slamming into gear, and the shifter itself being out of position. It's as though there is some misalignment that causes the shifter to move slowly out of "D" and just above it, and when it does this I have to move it into park and row it back to "D," else I can't get it back into gear. When I did this last night it developed some slop between P and R, and I could get it to actually hang halfway between the 2 positions and not pop back like it usually does. I don't know how else to describe this. When I told them the symptom originally, they seemed to know exactly what the issue was, and supposedly the "implausible" codes backed this up. But it's clearly something else. IdeaS?
