Porsche 911, 993 (EU)

Automatic transmission fluid capacity & service interval

Porsche 911, 993 (EU) models use automatic transmission fluid with a capacity of 9 liters. Service intervals include checks every 20000 km or 12 months and fluid changes every 40000 km. The data covers 5 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Porsche 911, 993 (EU) automatic transmission is a transaxle layout, meaning the gearbox and final drive are housed together at the rear axle rather than alongside the engine. A 9-liter fluid capacity reflects the combined volume of that integrated unit.
  • All five configurations across the 1993-1998 model range share an identical 9-liter transaxle capacity, covering the 911 Carrera, 911 Carrera (S), 911 Carrera 4, and 911 Carrera 4S variants without variation.
  • The rear-wheel-drive 911 Carrera and all-wheel-drive 911 Carrera 4 carry the same 9-liter transaxle capacity despite their differing drivetrain architectures, as specified across both the 1993-1995 and 1996-1998 model year groups.
  • A fluid check interval of 20,000 km or 12 months, whichever comes first, applies under normal use conditions across all listed configurations. The time-based threshold of 12 months means calendar time can trigger a check before the distance figure is reached.
  • The fluid change interval is set at 40,000 km under normal use conditions, which is exactly double the check interval of 20,000 km. A fluid check would therefore fall due once between each scheduled change.
  • No distinction in service intervals exists between the rear-wheel-drive and all-wheel-drive variants. The 911 Carrera 4 and 911 Carrera 4S follow the same 20,000 km check and 40,000 km change schedule as the standard 911 Carrera.
