Peugeot 403

Manual transmission fluid capacity & service interval

Peugeot 403 manual transmission fluid capacity ranges from 1,3 to 1,5 liters. Service intervals consist of a 3000 km check and a 6000 km change. 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 403 petrol variant carries a manual transmission fluid capacity of 1.5 liters, which represents a service fill volume typical of compact gearboxes from the mid-twentieth century era.
  • The 403 Diesel, introduced in 1958, has a notably smaller manual transmission fluid capacity of 1.3 liters, a difference of 0.2 liters compared to the petrol version despite sharing the same change interval schedule.
  • Both the petrol and diesel variants share an identical fluid check interval of 3,000 km under normal use conditions, reflecting the closer monitoring expectations common to vehicles of the period.
  • The change interval for manual transmission fluid is set at 6,000 km for both configurations under normal use, a relatively short interval by modern standards and consistent with the mechanical tolerances and lubricant technology available during the 1955-1966 production span.
  • The check interval of 3,000 km sits at exactly half the 6,000 km change interval, meaning a fluid level inspection falls precisely between each full drain-and-refill service cycle for both the petrol and diesel variants.
