Additional Notes

  • The Innocenti A40 manual transmission holds 1.5 liters of fluid, a figure that applies equally to both the A40 (1959-1961) and the A40S (1962-1967) variants.
  • A 4,000 km check interval is specified under normal use conditions for both configurations, meaning fluid level verification is due well before the full drain cycle.
  • The change interval is set at 20,000 km under normal use for both the A40 and A40S, placing the drain cycle at a relatively extended point relative to the check frequency.
  • The ratio of check interval to change interval is 1:5, with fluid level inspected five times for every single drain-and-fill service across both variants.
  • The 1.5-liter capacity is consistent across the entire 1959-1967 production span covered by the specifications, indicating no capacity revision accompanied the transition from the A40 to the A40S designation.
