Additional Notes

  • Across all listed Mazda CX-3 DK (EU) automatic transaxle configurations, the dry fill capacity stands at 7.8 liters, a figure that reflects the total fluid volume required when filling a completely drained or newly assembled unit with no residual fluid present in the torque converter or valve body.
  • The service fill capacity of 3.3 liters applies uniformly to every configuration in the specifications, representing the partial volume exchanged during a routine fluid change where the torque converter and internal passages retain fluid.
  • The gap between the 7.8-liter dry fill and the 3.3-liter service fill indicates that roughly 4.5 liters remain trapped in the transmission circuit during a standard drain-and-fill procedure, which is a common characteristic of automatic transaxles without a dedicated drain plug on the torque converter.
  • The check interval of 20,000 km or 12 months, whichever comes first, applies under normal use conditions across all five listed configurations, covering both diesel and petrol engine variants as well as both 2WD and 4WD drivetrains.
  • The SKYACTIV-D 1.5 (77 kW) 4WD, covering 2015-2018, and the SKYACTIV-D 1.8 (85 kW) 4WD, covering 2018-2020, share identical automatic transaxle fluid capacities and check intervals despite differing in engine displacement and output.
  • The SKYACTIV-G 2.0 petrol variants span a wider range of configurations, including a 110 kW 4WD version and an 88 kW 2WD version both covering 2015-2020, yet both share the same 7.8-liter dry fill, 3.3-liter service fill, and 20,000 km/12-month check interval as the diesel variants.
  • A later SKYACTIV-G 2.0 variant rated at 89 kW in 2WD configuration, covering 2020-2022, carries the same transaxle fluid specifications as the earlier 88 kW 2WD version, with no deviation in capacity or service interval.
