Additional Notes

  • The Mitsubishi Celeste (EU) automatic transmission fluid capacity is listed at 6,4 liters across all four configurations, covering both the 1600 A73 and 2000 A78 variants for the 1975-1980 period. A figure of this size typically reflects a total system fill, accounting for fluid held within the torque converter, valve body, and transmission pan combined.
  • The 1600 A73 and 2000 A78 share an identical 6,4-liter capacity, meaning the displacement difference between the two engines did not produce any variation in automatic transmission fluid volume requirements.
  • Under normal use conditions, both the 1600 A73 and 2000 A78 carry a fluid change interval of 80,000 km, while the check interval is set at 20,000 km regardless of use condition. The check interval remaining constant across both use conditions indicates fluid level monitoring was treated as a fixed maintenance point independent of operating severity.
  • Under severe use conditions, the change interval for both the 1600 A73 and 2000 A78 drops to 40,000 km, exactly half the 80,000 km normal interval. Severe use classifications generally account for operating environments that accelerate fluid degradation, such as frequent stop-and-go driving, towing, or high ambient temperatures, all of which increase thermal stress on automatic transmission fluid.
