Additional Notes

  • The Fiat 131 (EU) automatic transmission fluid capacity holds at 2.8 liters across all listed configurations, spanning the 1300 and 1600 variants from 1974-1977 through to the CL/L 1600 and Supermirafiori 1600 and 2000 variants from 1978-1984.
  • A 2.8-liter service fill is a relatively modest capacity for an automatic transmission, consistent with the compact unit sizes typical of European passenger cars from the 1970s and early 1980s.
  • The 131 1300 and 131 1600 from 1974-1977 share identical fluid specifications, with a 5,000 km check interval and a change interval of 40,000 km or 24 months under normal use conditions.
  • The 24-month time limit paired with the 40,000 km change interval on the 1974-1977 variants means fluid replacement is due whichever threshold is reached first, accounting for low-mileage usage patterns where calendar time becomes the governing factor.
  • The 131 CL/L 1600, 131 Supermirafiori 1600, and 131 Supermirafiori 2000, all from 1978-1984, carry only a 5,000 km check interval in the specifications, with no change interval listed for any of the three.
  • The 5,000 km check interval is consistent across all five configurations, indicating a uniform fluid level monitoring schedule regardless of engine displacement or model variant.
  • Despite the step up in displacement from 1600 cc to 2000 cc in the Supermirafiori range, the automatic transmission fluid capacity remains at 2.8 liters, identical to all other listed variants.
