Additional Notes

  • The Mazda CX-7 ER transfer case fluid capacity is rated at 1.2 liters for the 2.3 AWD configuration, which is a typical fill volume for a compact transfer case unit of the type used in crossover AWD systems.
  • Both the Canadian and American market variants of the 2.3 AWD share an identical 1.2-liter transfer case capacity across the full 2006-2012 model year span, indicating no regional mechanical differentiation in the transfer case assembly between the two markets.
  • The 1.2-liter figure represents a service fill capacity for the transfer case, meaning the volume required when draining and refilling the unit during a fluid service rather than a complete overhaul or rebuild scenario.
  • The capacity specification applies under normal use conditions for both the Canadian and American 2.3 AWD configurations, meaning the 1.2-liter fill volume is associated with standard operating environments rather than severe-duty cycles.
