Additional Notes

  • The Honda Civic IX FB/FG/FK manual transaxle specifications cover two distinct capacity figures for the 1.8 FB configuration: an initial fill of 1.6 liters and a service fill of 1.4 liters.
  • An initial fill capacity represents the total fluid volume required when the transaxle is dry, such as after a rebuild or replacement, while a service fill reflects the smaller volume needed when fluid is drained and refilled during routine maintenance.
  • The 0.2-liter difference between the 1.8 FB initial fill and service fill accounts for residual fluid that remains in the transaxle after a standard drain, which is a common characteristic of manual transmission service procedures.
  • The 1.8 FB transaxle specifications appear across two overlapping model year groupings, 2011-2014 and 2014-2015, both sharing identical capacity values of 1.6 liters initial fill and 1.4 liters service fill under normal use conditions.
  • The Civic Si 2.4 FB6/FG4 transaxle carries a service fill capacity of 1.9 liters, which is notably higher than the 1.4-liter service fill associated with the 1.8 FB transaxle, reflecting a physically larger gearbox unit paired with the higher-displacement engine.
  • The Civic Si 2.4 FB6/FG4 specification lists only a service fill value of 1.9 liters, with no separate initial fill figure present in the specifications for that configuration.
  • All three rows are designated under normal use conditions, meaning the listed capacities and service intervals apply to standard operating environments rather than severe-duty cycles.
