Additional Notes

  • The Porsche 981 Cayman's semi-automatic transaxle is serviced in two distinct fluid compartments, a clutch part and a transmission part, each with separate capacity figures rather than a single combined fill volume.
  • The clutch part of the transaxle holds 5.3 liters across all three variants, the Cayman, Cayman S, and Cayman GTS, for the 2013-2016 model years.
  • The transmission part of the same transaxle carries a notably smaller capacity of 2.9 liters, again consistent across all three variants for 2013-2016.
  • The combined fluid requirement for a full transaxle service on any of the three variants totals 8.2 liters when both the clutch part and transmission part are serviced together.
  • All six specification rows share an identical change interval of 180,000 km or 144 months, the latter equaling a 12-year calendar-based limit, whichever comes first under normal use conditions.
  • The 180,000 km interval is a long-life service schedule, reflecting the semi-automatic transaxle design rather than a conventional automatic gearbox with more frequent fluid degradation cycles.
  • No variation in capacity or service interval exists between the base Cayman, Cayman S, and Cayman GTS trims, indicating the same transaxle unit and fluid specification applies across the 981 lineup for 2013-2016.
  • All specifications are designated for normal use conditions, meaning the 180,000 km and 144-month intervals are not adjusted for any alternative operating condition within the data provided.
