Additional Notes

  • The Borgward Isabella manual transmission fluid capacity is 1 liter across all five variants covered for 1957-1962, which is a figure consistent with the compact gearbox designs typical of European passenger cars from that era.
  • A 1-liter fill is characteristic of a service fill specification, meaning the quantity reflects the working fluid volume in a transmission that remains in the vehicle, rather than a full overhaul or bench-fill measurement.
  • The fluid check interval is set at 4,000 km under normal use conditions, applying equally to the Combi, CoupĂ©/Cabrio, Standard, TS, and TS de Luxe variants.
  • The fluid change interval is 12,000 km under normal use conditions, which represents a 3:1 ratio between check and change intervals across all listed variants.
  • The normal use condition designation on all five rows means the 4,000 km check and 12,000 km change intervals are not adjusted for any more demanding operating environment within the listed specifications.
  • The Isabella 1500 TS and TS de Luxe share identical manual transmission fluid specifications with the lower-trim Standard and body-style variants, indicating no differentiation in gearbox servicing requirements between performance and standard trim levels within the 1957-1962 range.
