DS DS 9, X

Automatic transmission fluid capacity & service interval

DS 9 and X models utilize automatic transmission fluid with a capacity range of 2,5 to 6 liters. Service intervals are defined for normal use. The data covers 5 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • Across all five DS 9 configurations covered — the 1.6 PureTech 215 (EGP), 1.6 PureTech 225 (5GG), E-TENSE 225 (DGZ), E-TENSE 250 (DGY), and E-TENSE 4x4 360 (DGS) — the automatic transaxle carries a dry fill capacity of 6 liters.
  • A dry fill of 6 liters represents the total fluid volume required when filling a completely empty transmission, such as after a full overhaul or unit replacement where the torque converter and all internal passages have been drained.
  • The service fill capacity across all listed DS 9 variants is stated as a range of 2.5 to 3.5 liters, reflecting the variable amount of fluid that remains in the torque converter and valve body during a routine drain-and-fill service.
  • The gap between the 6-liter dry fill and the 2.5-3.5 liter service fill range indicates that roughly half or more of the total fluid volume is retained within the transmission during a standard service, which is typical behavior for automatic transaxles without a full disassembly drain.
  • All five configurations share identical capacity figures despite spanning petrol and plug-in hybrid powertrains, from the turbocharged 1.6 PureTech engines to the E-TENSE hybrid variants including the all-wheel-drive E-TENSE 4x4 360.
  • All specifications are listed under normal use conditions, meaning the stated capacities apply to standard operating environments rather than severe-duty cycles.
