Additional Notes

  • The Vauxhall Monaro automatic transmission fluid capacity is 5 liters across all listed configurations, covering the 5.7 V8, 5.7 VXR, and 6.0 VXR variants from 2004-2006.
  • A 5-liter service fill is consistent with a transaxle unit, where the transmission and final drive share a common housing, typically requiring a moderate fluid volume compared to separate drivetrain arrangements.
  • The change interval for all four configurations is set at 80,000 km or 24 months, whichever comes first, under normal use conditions.
  • The 24-month time-based threshold means a fluid change is due after two years regardless of mileage, which is relevant for lower-mileage vehicles that may not reach 80,000 km within that period.
  • The 5.7 V8 appears in two overlapping production windows, 2004-2005 and 2005-2006, both sharing identical capacity and interval specifications of 5 liters and 80,000 km/24 months.
  • The 5.7 VXR and 6.0 VXR variants also carry the same 5-liter capacity and 80,000 km/24-month interval, indicating no differentiation in automatic transmission fluid service requirements between the performance VXR trim and the standard V8 across the 2004-2006 range.
