When in cruise control (around 50mph) and going down a a fairly steep incline, the transmission disengages sending the vehicle into neutral but the gear shift lever does not move. It is then necessary to actually brake to a stop and re-engage Drive by physically shifting to neutral and then back to drive. This always happens under the circumstances above but has not happened at any other times.
