Citroën BX

Automatic transmission fluid capacity & service interval

Citroën BX automatic transmission fluid capacity ranges from 0,5 to 6 liters. Service intervals include checking at 10000 km and changing at 40000 km or 60000 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 Citroën BX 16 (1984-1993) carries a 6-liter automatic transaxle capacity, the largest among all BX automatic transmission configurations in the specifications.
  • The BX 14 (1988-1993) holds 4 liters in its automatic transaxle, a mid-range figure that reflects a smaller drivetrain relative to the BX 16.
  • The BX 19 GTi 16V (1987-1992) has a notably low automatic transaxle capacity of 2.5 liters, the smallest total fill volume listed across all BX automatic variants.
  • Both the BX 14 and BX 16 share a 60,000 km change interval under normal use conditions, while the BX 19 Diesel and BX 19 GTi 16V are each specified at a shorter 40,000 km change interval under the same conditions.
  • The BX 19 Diesel (1989-1993) is the only configuration in the specifications to include a separate filter capacity value, listed at 0.5 liter, indicating a discrete filter element that holds fluid independently of the main transaxle volume.
  • The BX 19 Diesel also carries a 10,000 km fluid level check interval alongside the 40,000 km change interval, a pairing not present in any other BX automatic transmission row in the specifications.
  • The absence of a total fill capacity figure for the BX 19 Diesel, with only a filter capacity of 0.5 liter listed, suggests the specifications address only the filter-related service volume rather than a full transaxle drain-and-fill quantity.
