Peugeot 504 Coupé/Cabriolet

Automatic transmission fluid capacity & service interval

Peugeot 504 Coupé/Cabriolet automatic transmission fluid capacity ranges from 2 to 5,2 liters. Service intervals include checking at 5000 km or 7500 km and changing at 15000 km or 45000 km/24 months. The data covers 2 configurations.

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

Additional Notes

  • The Peugeot 504 Coupé/Cabriolet automatic transmission holds 5.2 liters at dry fill, a figure that reflects the total fluid volume required when filling a fully drained or rebuilt unit, including the torque converter and all internal passages.
  • The refill capacity of 2 liters applies to a partial drain service, where residual fluid remains in the torque converter, representing less than half the dry fill volume.
  • Both the 1969-1971 and 1971-1983 configurations share identical dry fill and refill capacities of 5.2 liters and 2 liters respectively, indicating no change to the transmission unit's fluid volume requirements across the production span.
  • The 1969-1971 specification calls for a fluid check interval of every 5,000 km, compared to 7,500 km in the 1971-1983 specification, reflecting a tighter monitoring schedule in the earlier configuration.
  • The fluid change interval for the 1969-1971 configuration is set at 15,000 km under normal use conditions, which is notably shorter than the 45,000 km or 24-month interval introduced in the 1971-1983 specification.
  • The 1971-1983 change interval of 45,000 km or 24 months introduces a time-based limit alongside the distance-based one, meaning whichever threshold is reached first would govern the service requirement under normal use conditions.
  • The tripling of the change interval from 15,000 km to 45,000 km between the two configurations, both rated for normal use, represents a substantial revision to the service schedule across the 504 Coupé/Cabriolet's production history.
