Holden EK

Automatic transmission fluid capacity & service interval

Holden EK uses automatic transmission fluid with a capacity of 4,55 liters. Service intervals include checking at 1600 km and changing at 40000 km. The data covers 4 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Holden EK automatic transmission service fill capacity is 4.55 liters across all four body configurations: Panel Van, Special, Standard, and Utility.
  • A service fill figure represents the fluid volume required during a routine drain-and-refill service, which is typically less than the total system capacity because fluid retained in the torque converter and passages is not fully expelled during a standard drain.
  • The 1961-1962 model years share identical automatic transmission fluid specifications regardless of body style, with no variation recorded between the Panel Van, Special, Standard, or Utility configurations.
  • The check interval for the automatic transmission fluid is set at 1,600 km under normal use conditions, reflecting a relatively short inspection cycle consistent with maintenance practices of the early 1960s.
  • The fluid change interval is specified at 40,000 km under normal use conditions, applying uniformly to all four EK body configurations listed.
  • All four configurations carry a normal use condition designation, meaning the stated check and change intervals are not adjusted for severe operating environments such as towing, extreme temperatures, or stop-and-go driving.
