Additional Notes

  • The Opel Cascada W13 automatic transmission fluid specifications cover a transaxle unit across all listed configurations, meaning the gearbox and differential share a common housing and fluid supply.
  • The 1.6 Turbo variants in both 100 kW and 125 kW outputs carry a dry fill capacity of 8 to 8.5 liters, which represents the total fluid volume required when filling a completely drained or newly assembled unit.
  • Service fill capacity for the 1.6 Turbo configurations is listed at 4 to 6 liters, a notably lower figure than the dry fill, reflecting the volume of fluid that remains in the torque converter and passages during a routine drain-and-fill service.
  • The 2.0 CDTI (121 kW) covering 2013-2015 lists a single capacity figure of 6.7 liters without a separate dry fill or service fill distinction, which differs structurally from the capacity data presented for the 1.6 Turbo variants.
  • All four rows share an identical service interval of 12 months or 30,000 km under normal use conditions, applying equally across the 1.6 Turbo and 2.0 CDTI engine configurations.
  • The 1.6 Turbo 125 kW configuration spans two separate row entries covering 2013-2015 and 2015-2018, yet both carry identical capacity and interval specifications, indicating no change in fluid requirements across that production period.
  • The 1.6 Turbo 100 kW variant, listed for 2018-2019, shares the same 8 to 8.5 liter dry fill and 4 to 6 liter service fill figures as the higher-output 125 kW versions, suggesting a common transmission unit regardless of engine power output within the 1.6 Turbo family.
