Peugeot 604

Automatic transmission fluid capacity & service interval

Peugeot 604 automatic transmission fluid capacity ranges from 5,2 to 5,8 liters. Service intervals include checks at 5000 km and 7500 km, with fluid changes at 45000 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 Peugeot 604 D Turbo carries a 5.2-liter automatic transmission fluid capacity, which is 0.6 liters less than the 5.8-liter figure shared by the 604 SL and 604 Ti variants.
  • The 5.8-liter capacity on the 604 SL and 604 Ti represents a full service fill for the automatic transmission across those configurations.
  • All three variants share an identical drain-and-refill interval of 45,000 km or 24 months under normal use conditions, whichever comes first.
  • The 24-month time limit paired with the 45,000 km interval means the fluid change is due on whichever threshold is reached earlier, making calendar time as relevant as mileage accumulation.
  • The 604 D Turbo specifies a fluid level check every 5,000 km under normal use, while the 604 SL and 604 Ti both specify a check interval of 7,500 km under the same conditions.
  • The more frequent 5,000 km check interval on the 604 D Turbo, compared to the 7,500 km interval on the petrol variants, reflects the additional thermal and mechanical demands associated with turbocharged diesel operation on the automatic transmission.
  • The 604 SL and 604 Ti share identical capacity and interval figures across their respective production spans of 1975-1985 and 1977-1985, indicating no specification revision was made to the automatic transmission service data during those periods.
