Additional Notes

  • The Mazda Luce/Legato/929L automatic transmission fluid capacity figures across all listed configurations fall into two distinct values: 7.5 liters for the earliest Luce 1800 SVA (1968-1973) and 6.2 liters for all subsequent LA2/3 and LA4/5 variants from 1973 onward.
  • A 7.5-liter ATF capacity in the Luce 1800 SVA represents a notably larger fluid volume, which in automatic transmissions typically reflects a bigger torque converter or a deeper pan design relative to later units.
  • The reduction to 6.2 liters beginning with the LA2/3 generation in 1973 held consistent across both the 1800 and 2000 engine variants through the LA4/5 series ending in 1981, indicating a shared transmission unit regardless of engine displacement in those generations.
  • The 1800 and 2000 LA2/3 variants (1973-1977 and 1975-1977 respectively) share an identical check interval of 6000 km under normal use conditions, alongside the same 6.2-liter capacity.
  • The LA4/5 generation, covering both the 1800 and 2000 variants from 1977-1981, introduced a dual-condition check interval of 10000 km or 6 months under normal use, whichever comes first. The earlier LA2/3 series carried only a distance-based interval of 6000 km, making the LA4/5 interval specification notably more detailed.
  • The shift from a 6000 km distance-only check interval in the LA2/3 series to a 10000 km/6-month combined interval in the LA4/5 series applies equally to both the 1800 and 2000 engine configurations, reflecting a generation-level change rather than an engine-specific one.
