That's real odd. Seems like it may have been the shift selector on the transmission itself (since all of that's electronic - your shifter position doesn't really directly control the transmission solenoids).
Do our transmissions have a shift selector that has a hard link to the shifter, or does the shifter have an electronic gate system which completely electronically controls the transmission?
Either way, that could have been the point of failure. I would make the dealership do an extensive diagnostic before they hand the car back to you - they probably just think you're a moron, let them know you're not.
