Hillman Avenger

Automatic transmission fluid capacity & service interval

Hillman Avenger automatic transmission fluid capacity is 6 liters. Service intervals consist of checks every 8000 km or 6 months. The data covers 4 configurations.

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

Additional Notes

  • The Hillman Avenger automatic transmission fluid capacity is listed at 6 liters across all four configurations covered by the 1973-1976 specifications, with the notation that the torque converter adds volume beyond that figure.
  • The 6-liter figure represents a service fill capacity rather than a full overhaul or dry fill measurement, as the torque converter holds additional fluid that is accounted for separately.
  • A torque converter retains fluid even after a standard drain, so the total system volume in a complete rebuild or dry assembly scenario would exceed the stated 6 liters by a margin determined by the converter's own holding capacity.
  • The check interval for automatic transmission fluid across all listed Avenger variants is 8,000 km or 6 months, whichever comes first under normal use conditions.
  • The 8,000 km or 6-month check interval is a fluid level and condition inspection interval, not necessarily a full fluid change interval, as the specification uses the term "check" rather than "change" or "replace."
  • The 1300 and 1300 TC variants share identical automatic transmission fluid capacity and check interval specifications with the 1600 and 1600 TC variants, indicating no differentiation in transmission service requirements between the two engine displacements for the 1973-1976 model years.
  • The TC designation, applied to both the 1300 TC and 1600 TC, does not correspond to any variation in automatic transmission fluid capacity or service interval relative to the non-TC counterparts in the same engine family.
