Additional Notes

  • The Holden Statesman HQ manual transmission fluid capacity is specified at 2.13 liters across both the 308 HC and 350 HC engine variants for the 1971-1974 model years.
  • A 2.13-liter figure represents a service fill capacity, meaning the amount of fluid required when refilling a transmission already installed in the vehicle, rather than a full bench-overhaul quantity.
  • The 308 HC and 350 HC variants share an identical 2.13-liter manual transmission fluid capacity, indicating no variation between the two engine displacements in terms of gearbox fill volume.
  • Under normal use conditions, the manual transmission fluid check interval is set at 10,000 km or 12 months, whichever comes first.
  • The fluid change interval under normal use is 20,000 km or 12 months, meaning the time-based threshold of 12 months applies regardless of whether the distance figure has been reached.
  • The check interval of 10,000 km falls at exactly half the 20,000 km change interval, reflecting a structured two-stage service approach where fluid condition is assessed before a full drain and refill is due.
