Citroën 2CV

Manual transmission fluid capacity & service interval

Citroën 2CV manual transmission fluid capacity is 0,9 liter. Service intervals include checking every 10000 km and changing every 40000 km or 24 months. The data covers 3 configurations.

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

Additional Notes

  • The Citroën 2CV transaxle combines the transmission and final drive into a single unit, which is why the fluid capacity and service intervals apply to the transaxle as a whole rather than a separate gearbox.
  • All three trim variants covered here — the Charleston, Club, and Spécial — share an identical transaxle fluid capacity of 0.9 liter, indicating no mechanical differentiation between the trims in terms of the transmission assembly.
  • A 0.9 liter capacity is a notably small volume, consistent with the compact, lightweight drivetrain architecture of the 2CV platform across the 1984-1991 model years.
  • The check interval is set at every 10,000 km under normal use conditions, which is a routine top-up inspection rather than a full drain-and-fill service.
  • The fluid change interval is specified at 40,000 km or 24 months under normal use conditions, meaning whichever threshold is reached first would trigger the service requirement.
  • The 24-month time limit alongside the 40,000 km mileage threshold reflects that fluid degradation occurs over time regardless of distance driven, so low-mileage use does not exempt the transaxle from periodic fluid replacement.
