Additional Notes

  • Both the 4200 and 4900 engine variants share an identical manual transmission fluid capacity of 1.8 liters, indicating the same gearbox unit was used across the Maserati Quattroporte III, AM 330 range regardless of engine displacement.
  • The 1.8-liter figure represents a service fill capacity, which is the amount of fluid required during a standard drain-and-refill procedure rather than a full overhaul involving complete disassembly of the transmission housing.
  • Under normal use conditions, both variants specify a fluid check interval of every 5,000 km, with a full fluid change due at 10,000 km.
  • A separate first-change-only interval of 2,000 km applies to both the 4200 and 4900 variants, reflecting the standard practice of removing metal particles and contaminants generated during the initial break-in period of a new or rebuilt gearbox.
  • The first-change-only entry carries no check interval, only a change interval of 2,000 km, distinguishing it from the ongoing normal-use schedule that includes both check and change milestones.
  • The Quattroporte 4200 covers model years 1979-1983, while the 4900 variant spans 1979-1986, meaning the two engine configurations overlapped during the 1979-1983 period before the 4200 was discontinued.
