Additional Notes

  • The Honda Accord 1600 automatic transaxle carries a dry fill capacity of 4.2 liters across both the 1976-1978 and 1979-1981 model ranges. A dry fill figure represents the total fluid volume required when filling a completely empty transmission, such as after a full rebuild or replacement.
  • The service fill capacity is listed at 2.5 liters for all four configurations. A service fill reflects only the volume displaced during a routine drain, which is consistently lower than the dry fill because fluid remains trapped in the torque converter and passages during a standard service.
  • The gap between the 4.2-liter dry fill and the 2.5-liter service fill means roughly 1.7 liters of fluid stays in the transaxle during a normal drain-and-fill service. Overfilling to the dry fill volume during a routine service would result in excess fluid in the system.
  • Under normal use conditions, the change interval for the Accord 1600 automatic transaxle is 48,000 km for both the 1976-1978 and 1979-1981 configurations.
  • An initial service interval of 24,000 km is specified separately for both model year groups. Initial service intervals are typically shorter because new transmission components generate fine metallic particles during break-in, making an earlier fluid change beneficial for long-term component condition.
  • The specifications for the 1976-1978 and 1979-1981 Accord 1600 automatic transaxle are identical in every measured value, including dry fill, service fill, normal interval, and initial service interval, indicating no change in fluid system design between those two production periods.
