Additional Notes

  • The Peugeot 504 Coupé/Cabriolet built between 1969-1971 carries a manual transmission fluid capacity of 1.15 liters, while the 1971-1983 version holds 1.2 liters, a modest increase of 0.05 liters between the two generations.
  • The 504 V6 Coupé, produced from 1974-1983, has a notably larger manual transmission fluid capacity of 1.8 liters, which is 0.6 liters more than the standard 1971-1983 Coupé/Cabriolet specification of 1.2 liters.
  • A capacity of 1.8 liters in the V6 Coupé's manual transmission reflects a physically larger gearbox unit, consistent with the greater torque demands placed on the drivetrain by a V6 engine compared to an inline four-cylinder configuration.
  • The 1969-1971 Coupé/Cabriolet specifies a fluid check interval of 5,000 km under normal use conditions, whereas both the 1971-1983 Coupé/Cabriolet and the 504 V6 Coupé specify a check interval of 7,500 km under the same normal use conditions.
  • The change interval for the 1969-1971 Coupé/Cabriolet is set at 10,000 km under normal use, which is significantly shorter than the 30,000 km change interval applied to both the 1971-1983 Coupé/Cabriolet and the 504 V6 Coupé under the same normal use conditions.
  • A change interval of 10,000 km, as seen in the 1969-1971 specification, was common for early transmission service schedules of that era, reflecting older fluid formulations with lower oxidation resistance compared to later lubricant technologies that supported the extended 30,000 km intervals introduced from 1971 onward.
