Additional Notes

  • The Austin A99 Westminster carries an automatic transmission fluid capacity of 8.52 liters, a figure that reflects a full system fill rather than a simple drain-and-refill service quantity.
  • Under normal use conditions, the automatic transmission fluid interval calls for a change at 38,400 km, with a fluid level check scheduled at every 4,800 km.
  • An initial service check is specified at 800 km, a notably short interval compared to the 4,800 km routine check, reflecting the practice of inspecting fluid condition and level shortly after a new or freshly serviced transmission begins operation.
  • The initial service row carries a capacity figure of 8.52 liters, matching the normal use capacity, which indicates the same full-system volume applies regardless of whether the context is a break-in inspection or a standard service interval.
