Situation: The transmission may go into neutral without any driver input when driving at low vehicle and engine speeds; a flashing 'D'
may be evident on the transmission selector and 'Gearbox Fault' may be
displayed in the message center with no Diagnostic Trouble Codes (DTC) stored.
Cause: These may be caused by engine off detection calibration.
Action: In the event of a customer concern of the above, refer to the Repair Procedure outlined below to update the Engine Control
