    • Overall gear ratio: 7.937
    • Number of teeth:
      • Input gear: 17

  • The LEAF has a cooling system. Its coolant capacity is 7 quarts [2].
    The following components are liquid cooled: on-board charger, DC-DC converter, motor's inverter, and motor. Cooling flows through those components, in that order, before arriving back at the radiator. Two electric pumps in series pump coolant from the radiator past the coolant reservoir, into the pumps, then back out to the on-board charger. [3]

  • The LEAF has a parking mechanism which engages when one pushes the 'P' button on the "shift lever". A pawl engages a toothed gear in the reduction gearbox and prevent the transmission from turning:
