Additional Notes

  • The Chevrolet Impala (USA) manual transmission fluid specifications for 1961-1969 cover five engine variants: the 250, 283, 327, 396, and 427.
  • Each engine variant carries two listed capacity figures for the manual transmission: 0.83 liter and 1 liter. In manual transmission servicing, a lower capacity figure typically corresponds to a smaller gearbox unit, while a higher figure reflects a larger or different-ratio unit within the same model range.
  • The 0.83-liter capacity appears across all five engine variants — the 250, 283, 327, 396, and 427 — indicating a shared smaller transmission unit was available regardless of engine displacement.
  • The 1-liter capacity is similarly listed across all five engine variants, suggesting a second, larger transmission unit was also available throughout the full engine lineup during 1961-1969.
  • All ten specification rows carry a normal use condition, meaning none of the listed capacities or intervals are tied to severe-duty or first-change-only scenarios.
  • A 2-month check interval applies uniformly to every engine variant and both capacity figures under normal use conditions. A check interval, as distinct from a change interval, refers to inspecting fluid level rather than replacing the fluid entirely.
