Additional Notes

  • The manual transmission in the Austin A99 Westminster carries a fluid capacity of 3 liters, which applies to both the normal service fill and the initial service interval.
  • Under normal use conditions, the A99 Westminster's manual transmission fluid is checked at 1,500 km intervals and changed at 9,000 km intervals.
  • An initial service change is specified at 800 km, a notably short interval compared to the 9,000 km normal change cycle, reflecting the break-in period during which metal particles and manufacturing residues are flushed from the transmission.
