Additional Notes

  • The Vauxhall Astra 1.2 (1982-1984) manual transaxle carries a fluid capacity of 1.85 liters, while the 1.3 variant of the same generation lists two separate capacity figures — 1.75 liters and 1.85 liters — indicating that more than one transaxle unit was fitted across the 1.3 engine range during those years.
  • The 1.6 engine range mirrors the same split seen in the 1.3, with manual transaxle capacity listed at both 1.75 liters and 1.85 liters for the 1982-1984 period, reflecting the use of different gearbox assemblies within a single engine displacement class.
  • The 1.6 D diesel variant stands apart from the petrol-engined models, carrying a higher manual transaxle capacity of 2.0 liters against the 1.75 or 1.85 liters specified for the petrol 1.6.
  • The 1.8 GTE (1983-1984) holds the largest manual transaxle fluid capacity across all listed configurations at 2.1 liters, consistent with a higher-performance drivetrain requiring a greater fluid volume.
  • All petrol-engined variants — the 1.2, 1.3, 1.6, and 1.8 GTE — share a fluid check interval of 10,000 km or 6 months under normal use conditions.
  • The 1.6 D diesel is the only configuration in the 1982-1984 range specifying a tighter check interval of 5,000 km or 6 months under normal use, half the mileage interval applied to the petrol variants.
  • All seven listed configurations are designated as transaxle, manual units, meaning the gearbox and final drive share a common fluid sump — a layout common in front-wheel-drive vehicles of the era, where a single fill serves both functions.
