  "definition": "Overdrive, in general, refers to a top gear ratio of less than one. This refers to a transmission gear ratio and not necessarily a separate mechanical unit, as in the past. If a gear ratio is less than 1, the transmission output speed is greater than the input speed. Lower gear ratios will increase high speed fuel economy at the expense of torque.",
