Vauxhall Astramax

Automatic transmission fluid capacity & service interval

Vauxhall Astramax automatic transmission fluid capacity ranges from 6,3 to 7 liters. Service intervals require checks every 15000 km or 12 months. The data covers 5 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Vauxhall Astramax uses a transaxle-type automatic transmission across all listed engine variants, meaning the gearbox and final drive share a common fluid reservoir rather than being serviced as separate units.
  • The 1.3 petrol variant covering 1986-1989 carries a transaxle fluid capacity of 6.3 litres, which is the lowest figure across all listed configurations and reflects the smaller drivetrain associated with the 1.3 engine.
  • All remaining variants — the 1.6, 1.6 D, 1.6i, and 1.7 D — share a uniform transaxle fluid capacity of 7 litres, indicating a common transmission unit across those engine families regardless of fuel type or production period.
  • A capacity figure for a transaxle typically represents the total system fill, which is relevant when performing a full drain and refill during an overhaul, as opposed to a partial top-up during routine maintenance.
  • The check interval of 15,000 km or 12 months applies uniformly to all five variants under normal use conditions, meaning whichever threshold is reached first would trigger a fluid inspection.
  • The 1.6 petrol and 1.6 D diesel variants share identical transaxle capacity and check interval specifications across their common production window of 1986-1990, despite differing in engine fuel type.
  • The 1.6i variant, produced from 1991-1993, retains the same 7-litre capacity and 15,000 km / 12-month check interval as the earlier 1.6 petrol, suggesting continuity in the transmission specification across the model generation change.
  • The 1.7 D diesel, spanning 1989-1993, shares the 7-litre transaxle capacity with the petrol variants of equivalent displacement, which indicates the automatic transaxle unit was not diesel-specific in its fluid volume requirements.
