Additional Notes
- The Porsche 911 996 (USA) Carrera and Carrera 4 rear differential, sourced from the automatic transmission, share an identical 0.8 liter capacity for the 1998-2001 model years under normal use conditions.
- The 911 Carrera 4 (1998-2001) front differential carries a 1.5 liter capacity under normal use, which is notably higher than the 0.8 liter figure associated with the rear differential on the same variant.
- The presence of a front differential entry exclusive to the Carrera 4 reflects the all-wheel-drive architecture of that variant, which requires an additional differential unit not present in the rear-wheel-drive Carrera.
- The 911 Turbo (2000-2006) rear differential, also noted as sourced from the automatic, holds 1.2 liters under normal use conditions, a larger capacity than the 0.8 liter figure specified for the Carrera and Carrera 4 rear differentials of the 1998-2001 period.
- All four rows carry a normal use condition designation, meaning none of the listed capacities are tied to a severe-duty or first-change-only service scenario.
- The "from automatic" notation on the rear differential entries across all three variants indicates the differential unit is integrated with or derived from the automatic transmission assembly, which is a relevant factor when determining the correct service fill volume.
