Additional Notes

  • The Porsche 718 Boxster 982 manual transaxle holds 3.2 liters of fluid across all listed configurations, spanning the base model, the S trim, and the GTS 4.0 variant. A transaxle combines the transmission and differential into a single housing, and a 3.2-liter fill is consistent with a unit of that integrated design.
  • The 3.2-liter figure represents a service fill capacity, meaning the amount of fluid required when draining and refilling during a standard maintenance procedure, rather than a full overhaul or bench-rebuild quantity, which would typically account for additional fluid retained in internal passages and components.
  • The change interval for all listed configurations is 144 months or 120,000 miles under normal use conditions, whichever comes first. At 144 months, the time-based limit equals 12 years, making the mileage threshold the more likely limiting factor for vehicles driven at average annual rates.
  • The normal use condition tied to the 144-month/120,000-mile interval reflects standard operating environments, as opposed to severe-use classifications that typically apply to vehicles subjected to frequent towing, track driving, or extreme temperature exposure. No separate severe-use interval appears in the listed specifications.
  • The base 718 Boxster carries the same 3.2-liter capacity and 144-month/120,000-mile interval across the 2016-2018 and 2018-2020 entries, with no variation in either value between those two model year groupings.
  • The 718 Boxster GTS 4.0, which uses a naturally aspirated flat-six engine rather than the turbocharged flat-four found in earlier variants, shares the identical 3.2-liter transaxle fluid capacity and change interval as the other configurations listed, indicating the manual transaxle unit itself is consistent across engine variants in the 982 generation.
