Additional Notes

  • Across all Hudson Super configurations from 1946-1951, the manual transmission without overdrive carries a fluid capacity of 0.91 kg, while the manual transmission paired with overdrive requires 1.47 kg, representing a difference of 0.56 kg attributable to the overdrive unit's additional fluid volume.
  • The 0.91 kg capacity figure applies uniformly to the standard manual transmission in both the Super Six and Super Eight, across both the 1946-1947 and 1948-1951 model year groupings.
  • The 1.47 kg capacity for the manual-plus-overdrive configuration is likewise consistent across the Super Six and Super Eight variants for the full 1946-1951 span, indicating no engine-related variation in overdrive fluid requirements.
  • All eight configurations share an identical service interval structure under normal use conditions: a fluid level check at 1,000 miles and a full fluid change at 5,000 miles.
  • The 1,000-mile check interval is notably short by later automotive standards, reflecting mid-century service practices where frequent inspections were standard for mechanical components.
  • The 5,000-mile change interval applies equally to both the standard manual and the manual-plus-overdrive setups, meaning the presence of the overdrive unit does not alter the drain schedule despite the increased fluid volume.
  • No specification differences exist between the 1946-1947 and 1948-1951 Super Eight entries for either transmission configuration, with capacities and intervals remaining unchanged across the two model year groups.
  • The same holds for the Super Six: the 1946-1947 and 1948-1951 entries share identical capacity and interval values for both the standard manual and the overdrive-equipped variant.
