Additional Notes

  • The SsangYong Rexton e-XDi220 automatic transmission holds 9 liters across the Y400 generation in both 2WD and 4WD configurations for the 2017-2021 model years.
  • The Y450 2WD variant introduced from 2021 carries a slightly higher automatic transmission fluid capacity of 9.1 liters, whereas the Y450 4WD retains the 9-liter figure shared with the Y400 generation.
  • Under normal use conditions, all configurations across both the Y400 and Y450 generations specify a fluid check interval of 12 months or 30,000 km, with no drain-and-fill change interval listed for normal use.
  • Under severe use conditions, the check interval across all configurations is expressed as 30,000 km or 12 months, and a fluid change interval of 60,000 km is specified alongside the check schedule.
  • The distinction between normal and severe use intervals is meaningful here because severe conditions add an explicit 60,000 km change requirement that does not appear in the normal use rows, making operating environment a direct factor in service planning.
  • The 9-liter capacity figure is consistent across the Y400 2WD, Y400 4WD, and Y450 4WD configurations, indicating a shared transmission unit across those variants regardless of drivetrain layout or generation.
  • The 0.1-liter difference between the Y450 2WD capacity of 9.1 liters and the Y450 4WD capacity of 9 liters suggests a variation in the transmission assembly or sump specification between the two drivetrain options within the same generation.
