Peugeot 309

Automatic transmission fluid capacity & service interval

Peugeot 309 automatic transmission fluid capacity is 2 liters. Service intervals require a check every 60000 km. The data covers 2 configurations.

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

TypeSpecifications
309 1.6 (1985-1993)
  • Use: Normal
  • Capacity 2 liter
  • Check 60000 km
  • Code: 4/1
309 1.9 (1985-1993)
  • Use: Normal
  • Capacity 2 liter
  • Check 60000 km
  • Code: 4/1

Additional Notes

  • Both the 1.6 and 1.9 engine variants share an identical automatic transaxle fluid capacity of 2 liters, which is characteristic of a service fill rather than a full overhaul drain, where total system volume would typically be higher.
  • A transaxle configuration combines the transmission and drive axle into a single unit, a layout common in front-wheel-drive vehicles, and the 2-liter figure reflects the fluid volume held within that integrated assembly.
  • The Peugeot 309 1.6 and 1.9 automatic transaxle specifications both carry a check interval of 60,000 km under normal use conditions, meaning the interval applies to standard driving rather than demanding or high-stress operating environments.
  • The 60,000 km figure is designated as a check interval rather than a change interval, indicating a fluid level or condition inspection is specified at that mileage point rather than a mandatory full fluid replacement.
  • Across the full 1985-1993 model year span covered by the specifications, no variation in capacity or check interval is recorded between model years for either the 1.6 or 1.9 engine configuration.
