Fiat 124 (EU)

Automatic transmission fluid capacity & service interval

Fiat 124 (EU) automatic transmission fluid capacity ranges from 2,8 to 5,6 liters. Service intervals include checking at 5000 km and changing at 40000 km or 24 months. The data covers 4 configurations.

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

Additional Notes

  • The Fiat 124 (EU) automatic transmission carries a dry fill capacity of 5.6 liters across the 124 (1966-1970), 124 Special (1971-1973), and 124 Special T (1968-1970) variants, a figure that reflects the total fluid volume required when filling a fully drained or rebuilt unit, including the torque converter and all internal passages.
  • Refill capacity for those same three variants is listed at 2.8 liters, exactly half the dry fill volume, which is consistent with a routine drain-and-fill procedure where residual fluid remains in the torque converter and valve body.
  • The Spider 2000 (1978-1982) lists only a single capacity value of 2.8 liters with no separate dry fill figure, indicating the specification covers a refill-type service rather than a complete overhaul fill.
  • Under normal use conditions, the 124 (1966-1970), 124 Special (1971-1973), and 124 Special T (1968-1970) share an identical service interval of 40,000 km or 24 months, whichever comes first, for a fluid change.
  • The Spider 2000 (1978-1982) carries a change interval of 40,000 km under normal use but does not include a time-based interval alongside the distance figure, unlike the earlier three variants.
  • All four variants specify a fluid level check interval of 5,000 km under normal use conditions, a relatively short inspection cycle that reflects standard maintenance practice for automatic transmissions of that era.
  • The 124 Special T (1968-1970) shares its full specification set with the base 124 (1966-1970) despite being a distinct trim, with identical dry fill, refill, check, and change intervals across both configurations.
