Additional Notes

  • The Porsche 718 Cayman (982) manual transaxle fluid capacity is 3.2 liters across all listed configurations, from the base model to the GTS 4.0 variant. A transaxle combines the transmission and differential into a single housing, and a 3.2-liter fill volume reflects a mid-size unit typical of rear-mid-engine sports cars.
  • The 3.2-liter figure applies as a service fill capacity, meaning the amount used during a fluid change with the unit installed in the vehicle. Overhaul or bench-fill capacities for a fully drained and disassembled unit can differ, but the specifications here reflect the standard service procedure.
  • The change interval is uniform at 144 months or 120,000 miles across every listed configuration. At 144 months, the time-based limit equals 12 years, making the mileage threshold the more likely limiting factor under typical driving conditions.
  • All rows carry a normal use condition designation. The 120,000-mile and 144-month interval applies specifically under normal operating conditions, not severe use such as track driving, towing, or extreme temperature exposure.
  • The 718 Cayman base model spans two overlapping row entries covering 2016-2018 and 2018-2020, with a third entry starting from 2020. Despite the year overlap in the first two rows, the fluid capacity and change interval remain identical at 3.2 liters and 144 months/120,000 miles.
  • The 718 Cayman S appears in entries covering 2018-2020 and from 2020 onward. Both share the same 3.2-liter transaxle capacity and 144-month/120,000-mile interval as the base model, indicating no difference in manual transaxle fluid servicing between the S trim and the standard variant.
  • The 718 Cayman GTS 4.0 carries a naturally aspirated flat-six engine rather than the turbocharged flat-four found in earlier 718 variants, yet the manual transaxle fluid capacity and service interval remain at 3.2 liters and 144 months/120,000 miles, consistent with all other listed configurations.
