Additional Notes

  • The Porsche 911 Carrera, 964 (EU) automatic transaxle holds 9 liters of fluid, a figure consistent with a full service fill for a rear-mounted transaxle unit of that era.
  • The 40,000 km or 48-month change interval applies under normal use conditions, meaning routine driving without the added thermal and mechanical stress associated with severe use classifications.
  • A separate check interval of 20,000 km or 12 months is specified alongside the change interval, placing the fluid level inspection at roughly the halfway point between full drain-and-fill services.
  • The 48-month time limit on the change interval means a calendar-based threshold can be reached before the distance figure, particularly in lower-mileage applications where annual driving falls well under 10,000 km.
  • The transaxle layout of the 911 Carrera, 964 places the automatic gearbox at the rear axle, separate from the engine, which accounts for the dedicated fluid capacity and service schedule independent of engine oil intervals.
