Additional Notes

  • The Porsche 904 Carrera GTS (EU) transaxle holds 2.5 liters of manual transmission fluid, a figure that applies uniformly across both the standard and Sport variants for the 1963-1965 model years.
  • The 2.5-liter capacity is listed for the transaxle unit specifically, which in the 904 Carrera GTS combines the transmission and final drive into a single integrated housing mounted at the rear of the vehicle.
  • Both normal and competition use conditions are associated with the same 2.5-liter capacity across all four listed configurations, meaning the fluid volume requirement does not change between road and competition service contexts for the 1963-1965 transaxle.
  • The standard 904 Carrera GTS and the 904 Carrera GTS Sport share an identical 2.5-liter transaxle capacity for both use conditions, indicating no differentiation in fluid volume between the two trim designations.
