Vauxhall VX4/90

Automatic transmission fluid capacity & service interval

Vauxhall VX4/90 automatic transmission fluid capacity ranges from 2,3 to 2,56 liters for service fills. Service intervals include checks every 10000 km or 3 months and changes every 20000 km or 6 months. The data covers 3 configurations.

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

Additional Notes

  • The Vauxhall VX4/90 FC (1964-1967) carries a service fill capacity of 2.3 liters for the automatic transmission, which represents the partial refill volume used during a routine fluid change rather than the total system volume.
  • From the FD generation onward (1967-1972), the service fill capacity rises to 2.56 liters, a modest but measurable increase over the FC figure of 2.3 liters.
  • The FE generation (1972-1976) retains the same 2.56-liter service fill capacity as the FD, placing both later generations in alignment on that specification.
  • Across all three generations, the automatic transmission fluid check interval is set at 10,000 km or 3 months under normal use conditions, whichever comes first.
  • The fluid change interval across all three generations is 20,000 km or 6 months under normal use conditions, meaning the change interval is exactly double the check interval in both distance and time.
  • All three generations share identical check and change intervals despite the capacity difference between the FC and the later FD and FE variants, indicating the service schedule was not revised alongside the capacity adjustment.
