Automatic transmission fluid capacity & service interval

Renault 9, X42 (EU) automatic transmission fluid capacity ranges from 3 to 4 liters. Service intervals occur every 60000 km. The data covers 2 configurations.

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

Additional Notes

  • The Renault 9 X42 carries a dry fill capacity of 4 liters for the automatic transaxle, which represents the total fluid volume required when filling a completely drained or rebuilt unit from empty.
  • The service fill capacity is 3 liters, reflecting the smaller volume needed during a routine fluid change, where residual fluid remains in the torque converter and passages after draining.
  • The 1-liter difference between the dry fill and service fill figures is a direct consequence of fluid retained in the torque converter, which does not drain fully through the pan drain plug alone.
  • Both the 1.4 (50 kW) and 1.4 (53 kW) automatic variants share identical fluid capacities of 4 liters dry and 3 liters service, indicating the same transaxle unit is used across both power outputs for the 1981-1989 production span.
  • The specified change interval for both configurations is 60,000 km under normal use conditions, meaning the interval applies to standard driving rather than elevated-stress operating environments.
