Holden Commodore, VB

Automatic transmission fluid capacity & service interval

Holden Commodore, VB automatic transmission fluid capacities range from 2,3 to 10,4 liters. Service intervals consist of checks every 20000 km or 12 months and changes every 40000 km or 24 months. The data covers 9 configurations.

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

Additional Notes

  • The Holden Commodore VB 3.3 automatic carries a service fill capacity of 2.3 liters, which represents the fluid volume needed when draining and refilling during a routine service without removing the torque converter.
  • The dry fill capacity for the 3.3 automatic is 8.7 liters including the converter, a figure that applies when the transmission is fully stripped and reassembled, such as during an overhaul or complete unit replacement.
  • Across the 4.2-liter variants, two distinct service fill capacities appear: 2.3 liters and 3.7 liters, indicating that two different automatic transmission units were fitted to the same engine across the 1978-1980 model range.
  • The 4.2-liter configurations carrying the larger transmission unit show a dry fill capacity of 10.4 liters including the converter, compared to 8.7 liters for the smaller unit, reflecting a meaningfully larger total fluid volume in the drivetrain.
  • The same two-transmission pattern seen in the 4.2-liter engines also applies to both 5.0-liter outputs, the 114 kW and 125 kW variants, each listing either a 2.3-liter or 3.7-liter service fill depending on the transmission fitted.
  • For all configurations where interval data is present, the fluid check interval is set at 20,000 km or 12 months under normal use conditions, whichever comes first.
  • The fluid change interval under normal use conditions is 40,000 km or 24 months, meaning a full drain and refill to the 2.3-liter or 3.7-liter service fill figure is due at twice the frequency of the check interval.
  • The 3.7-liter service fill rows across the 4.2, 5.0 (114 kW), and 5.0 (125 kW) engines carry no check or change interval data, meaning no km or time-based service schedule is recorded for those particular transmission configurations.
