Additional Notes

  • The Porsche 944 (EU) manual transmission fluid capacity holds at 2 liters across all four variants covered — the base 944, 944 S, 944 S2, and 944 Turbo — reflecting a consistent transaxle design rather than variation driven by engine output or trim level.
  • A 2-liter transaxle fill is a relatively modest volume, consistent with a rear-mounted manual transaxle unit where the gearbox and final drive share a common housing, as found in the 944's torque-tube drivetrain layout.
  • The base 944 (1981-1989) and 944 S (1986-1988) rows carry only a capacity figure with no check or change interval listed, while the 944 S2 (1988-1991) and 944 Turbo (1985-1991) rows include both a check interval of 20,000 km or 12 months and a change interval of 80,000 km or 48 months under normal use conditions.
  • The 80,000 km or 48-month change interval on the 944 S2 and 944 Turbo represents a long-cycle service schedule, meaning fluid replacement is not required at every routine service visit but rather at a defined extended mileage or time threshold, whichever comes first.
  • The 20,000 km or 12-month check interval on the 944 S2 and 944 Turbo under normal use is a fluid level inspection interval, not a replacement interval, serving to confirm the transaxle retains its full 2-liter fill between scheduled changes.
  • The 944 S covered a production window of 1986-1988, and within that period the manual transaxle capacity matched the base 944 at 2 liters, with no separate interval data specified for the variant.
