This sounds like a bad ground from either your vehicle's Power-train Control Module (PCM) or "computer", or the Transmission Control Module (TCM). It could possibly be a Connector Area Network(CAN) or "computer lines" issue. Whatever it was, it will be impossible to diagnose until it happens again. Is your Malfunction Indicator Lamp (MIL) or "check engine" light illuminated?
