Additional Notes

  • The Vauxhall Astra automatic transaxle fluid capacity is 7 liters across the 1.3, 1.6, and 1.6 D engine variants for 1982-1984, indicating a full transaxle service fill rather than a partial drain-and-refill figure.
  • All three variants share a 40000 km fluid change interval under normal use conditions, placing the drain cycle at a relatively extended mileage point for the era.
  • The 1.6 D variant pairs the 40000 km change interval with a 48-month time limit, meaning whichever threshold is reached first would govern the service event.
  • The 1.3 and 1.6 petrol variants carry a fluid check interval of 10000 km or 6 months, whichever comes first under normal use conditions.
  • The 1.6 D diesel variant has a more frequent check interval of 5000 km or 6 months, half the distance interval of the petrol variants, despite sharing the same 7-liter capacity and 40000 km change interval.
  • The note designation of "transaxle, automatic" across all three rows confirms the automatic gearbox and final drive share a common fluid sump, which accounts for the relatively high 7-liter capacity figure.
