Additional Notes

  • The Austin A55 manual transmission holds 2.56 liters of fluid across all three configurations covered by these specifications: the Cambridge Mk I, Cambridge Mk II, and Countryman.
  • A 2.56-liter fill is a moderate capacity for a manual gearbox of this era, consistent with a compact four-speed unit rather than a larger overdrive or heavy-duty transmission assembly.
  • The fluid check interval is set at 1,500 km under normal use conditions, which reflects a relatively short inspection cycle and points to the maintenance expectations common in mid-20th century vehicle servicing practice.
  • The fluid change interval is 9,000 km under normal use conditions, applying equally to the Cambridge Mk I (1957-1958), Cambridge Mk II (1959-1961), and Countryman (1960-1961).
  • The uniformity of capacity and interval figures across all three body configurations suggests the Austin A55 used the same manual transmission unit regardless of whether the vehicle was a standard saloon or the estate-bodied Countryman variant.
