Citroën ZX

Automatic transmission fluid capacity & service interval

Citroën ZX automatic transmission fluid capacity is 2,5 liters. Service intervals include checking at 10000 km, 20000 km, and 25000 km, with changes at 40000 km and 50000 km. The data covers 6 configurations.

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

Additional Notes

  • All six configurations of the Citroën ZX with automatic transmission share a transaxle fluid capacity of 2.5 liters. A transaxle combines the transmission and final drive into a single housing, so this figure represents the service fill volume for that integrated unit rather than a separate gearbox alone.
  • The 2.5-liter capacity figure is consistent across the 1.8i, 1.9 D, and 2.0i engine variants, spanning the full 1992-1998 model range covered by these specifications. No engine type or model year within the listed configurations deviates from this value.
  • The ZX 1.8i in its 1993-1994 configuration carries a fluid change interval of 50,000 km under normal use conditions. The 1994-1998 version of the same engine reduces the change interval to 40,000 km, aligning with the intervals specified for the 1.9 D and 2.0i variants.
  • The check interval for the ZX 1.8i also differs between the two production periods. The 1993-1994 specification sets a check at 25,000 km, while the 1994-1998 specification shortens the check interval to 20,000 km under normal use conditions.
  • The ZX 1.9 D in its 1992-1993 configuration carries a notably shorter check interval of 10,000 km under normal use conditions, compared to the 20,000 km check interval specified for the same engine in the 1994-1998 period. The fluid change interval of 40,000 km remains the same across both periods for the 1.9 D.
  • The ZX 2.0i specifications are identical across both the 1992-1993 and 1994-1997 periods, with a 20,000 km check interval and a 40,000 km change interval under normal use conditions. The capacity of 2.5 liters also remains unchanged between the two periods.
  • All specifications in the listed configurations apply to normal use conditions. In automotive service terminology, normal use typically refers to standard driving patterns as opposed to severe conditions such as frequent towing, extreme temperatures, or predominantly short-trip driving.
