Fiat 126 (EU)

Manual transmission fluid capacity & service interval

Fiat 126 (EU) manual transmission fluid has a capacity of 1,1 liters. Service intervals include checking at 10000 km and changing at 30000 km. The data covers 2 configurations.

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

Additional Notes

  • The Fiat 126 (EU) manual transmission fluid specifications cover a transaxle unit, meaning the gearbox and final drive share a single combined housing and a single fluid fill rather than separate reservoirs.
  • Both the 126 0.6 / 126A (1972-1978) and the 126 0.65 / 126A1 (1977-1982) configurations carry an identical transaxle fluid capacity of 1.1 liters, indicating a very compact drivetrain consistent with the vehicle's small displacement engines.
  • A 1.1-liter capacity is characteristic of a service fill level, representing the working volume of fluid the transaxle holds during normal operation rather than a larger overhaul quantity that would account for residual fluid in disassembled components.
  • The fluid check interval is set at 10,000 km for both configurations under normal use conditions, meaning periodic inspection of the fluid level is expected well before a full drain and refill becomes due.
  • The fluid change interval is specified at 30,000 km under normal use for both the 126A and 126A1 variants, placing the drain-and-refill cycle at three times the distance of each scheduled check.
  • The 1977-1978 period represents an overlap between the two configurations, as the 126A covers 1972-1978 and the 126A1 begins in 1977, yet both share identical capacity and interval specifications across that overlapping window.
