Peugeot 504

Automatic transmission fluid capacity & service interval

Peugeot 504 automatic transmission fluid capacity ranges from 2 to 5,2 liters. Service intervals include checking at 5000 km and changing at 15000 km. The data covers 3 configurations.

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

  • Code: 3/1

Additional Notes

  • The Peugeot 504 automatic transmission carries a dry fill capacity of 5.2 liters, which represents the total fluid volume required when filling a completely drained or rebuilt unit from empty.
  • The refill capacity of 2 liters is notably lower than the dry fill figure, reflecting the volume that remains trapped in the torque converter and valve body during a standard drain procedure rather than a full overhaul.
  • The gap between the 5.2-liter dry fill and the 2-liter refill means that a routine fluid change replaces less than half the total system volume, which is a common characteristic of automatic transmissions without a dedicated drain plug for the torque converter.
  • A fluid level check interval of 5,000 km applies to the 504, 504GL, and 504Ti under normal use conditions, indicating how frequently the transmission fluid level is to be inspected between full change services.
  • The fluid change interval is set at 15,000 km under normal use conditions across all three variants, meaning the 2-liter refill quantity is the working volume exchanged at each scheduled service.
  • The 504GL and 504Ti, both introduced in 1971, share identical automatic transmission fluid capacities and service intervals with the base 504 that dates to 1968, indicating no specification differentiation between the trim levels for this system.
