I cant pin point where I read the information, but it was a dodge charger or chrysler 300 - in which the owner shifted to neutral to "hypermile"

The transmission control went into error and locked up in its final gear (5th) - upon restart it had 2nd only. The remedy was to clean out the errors as it was showing a "transmission range error" of some sorts which requires some advanced code reader to read and clean.
