Additional Notes

  • The Volvo FL-12 (EU) manual transmission specifications cover three engine output variants of the D12A engine across the 1995-1998 production period: the FL 12-340, FL 12-380, and FL 12-420.
  • Two distinct capacity values appear across the FL 12-340 and FL 12-380 variants: 12 liters and 13.5 liters. In manual transmission servicing, differing fill capacities for the same engine variant typically reflect different gearbox units installed in the vehicle, each with a unique internal volume.
  • The FL 12-340 (D12A) carries three separate capacity entries under normal use conditions, with one entry at 12 liters and two entries at 13.5 liters, indicating at least two distinct transmission units were fitted to the 340-horsepower configuration.
  • The FL 12-380 (D12A) mirrors the same capacity pattern as the FL 12-340, with one 12-liter entry and two 13.5-liter entries under normal use conditions, suggesting a shared range of compatible gearbox options between the two output ratings.
  • The FL 12-420 (D12A) lists only 13.5-liter capacity entries across both of its normal-use rows, with no 12-liter figure present for the highest-output variant in the 1995-1998 range.
  • All eight specification rows across the FL-12 (EU) manual transmission data are designated for normal use conditions, meaning none of the listed capacities are tied to severe-duty or first-change-only service distinctions.
  • A 13.5-liter fill capacity is a substantial volume for a manual transmission, consistent with heavy-duty multi-axle truck gearboxes where larger fluid reservoirs support thermal management under sustained load conditions.
