Additional Notes

  • The Fiat 125 Special and 125B (1970-1972) carry a manual transmission fluid capacity of 1.65 liters, which is notably higher than the 1.35-liter figure shared by all other variants in the lineup, reflecting a physically larger or differently configured gearbox unit in those trims.
  • The 125, 125A, and 125P/115C variants all share an identical 1.35-liter manual transmission fluid capacity, a value consistent across both the 1967-1969 and 1970-1972 model year groupings of the 125 and 125A.
  • A check interval of 10,000 km applies uniformly across all four configurations under normal use conditions, meaning the fluid level is inspected at that mileage point without a full drain and refill being required.
  • The change interval of 30,000 km is consistent across all listed variants under normal use, indicating a full fluid replacement is due at that mileage regardless of whether the vehicle is a 125, 125A, 125 Special, 125B, 125P, or 115C.
  • The 125P and 115C share a single specification row covering 1967-1980, with a 1.35-liter capacity and the same 10,000 km check and 30,000 km change intervals that apply to the other normal-use configurations.
  • All specifications across the four rows are designated for normal use conditions, meaning no separate severe-use intervals or capacities are listed for any of the manual transmission configurations in the Fiat 125 (EU) range.
