Additional Notes

  • The Mazda CX-9 TC automatic transaxle carries a dry fill capacity of 8 liters, a figure that represents the total fluid volume required when filling a completely empty unit, such as after a full overhaul or replacement.
  • The service fill capacity is listed as a range of 3.5 to 4.9 liters, which reflects the variable amount of fluid retained in the torque converter and valve body after a drain, meaning the actual refill quantity depends on how thoroughly the system was evacuated.
  • The gap between the 8-liter dry fill and the 3.5 to 4.9-liter service fill range indicates that a standard drain-and-fill procedure replaces roughly half or less of the total fluid volume in the transaxle.
  • All four configurations share identical dry and service fill capacities, meaning the AWD and front-wheel-drive variants of the SKYACTIV-G 2.5 T use the same automatic transaxle fluid volume specifications.
  • The Canadian and American market versions of each drivetrain configuration carry the same capacity figures, with no regional variation in fluid volume specifications across any of the listed rows.
  • The FWD configurations cover model years 2015-2023, while the AWD configurations begin from 2016-2023, making 2015 a year in which only the FWD transaxle fluid specifications apply.
  • All listed specifications are designated for normal use conditions, and no separate severe-use interval or capacity variation is listed for any of the four configurations.
