Additional Notes

  • The Dodge Challenger's manual transmission fluid specifications list two distinct capacity values for each engine configuration: 4.5 liters and 7.1 liters. In manual transmission service, a smaller figure typically represents a service or top-up fill, while a larger figure reflects the total overhaul or dry fill capacity of the gearbox.
  • The 318ci engine variant carries both the 4.5-liter and 7.1-liter capacity entries across the full 1970-1974 model year span, meaning both service and overhaul fill volumes apply throughout the entire production range covered by the specifications.
  • The 360ci engine variant shares the same two capacity values — 4.5 liters and 7.1 liters — as the 318ci, though the 360ci configuration appears only from 1973-1974 rather than the full 1970-1974 range.
  • All four specification rows are designated for normal use conditions, indicating no separate severe-duty interval or capacity distinction is listed for either engine displacement in the manual transmission fluid data.
  • The presence of identical capacity figures across both the 318ci and 360ci variants suggests the manual transmission unit fitted to the Dodge Challenger did not change in fluid volume requirements between the two engine displacements, despite the difference in engine size.
