Fiat-Trattori 90

Manual transmission fluid capacity & service interval

Fiat-Trattori 90 manual transmission fluid capacity ranges from 11,7 to 52,9 liters. Service intervals include checking every 400 hours and changing every 1600 hours. The data covers 10 configurations.

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

Additional Notes

  • Across the Fiat-Trattori 90 series, manual transmission fluid capacities fall into three distinct groups: 11.7 liters, 18.3 liters, and 21.1 liters, with a separate and substantially larger 52.9-liter figure applying exclusively to the HI-LO variants.
  • The 11.7-liter capacity applies to the 90-90, 90-90 DT, 100-90, 100-90 DT, and 110-90 DT configurations, representing the smallest transmission fill volume within the series.
  • The 115-90, 115-90 DT, 130-90 DT, and 140-90 DT share an 18.3-liter capacity, a figure roughly 56 percent greater than the 11.7-liter group, reflecting a larger transmission housing in higher-output configurations.
  • The 160-90 DT and 180-90 DT carry a 21.1-liter capacity, the largest among the non-HI-LO variants, consistent with the heavier-duty transmission assemblies found in the upper power range of the series.
  • The 70-90 HI-LO, 70-90 DT HI-LO, 80-90 HI-LO, and 80-90 DT HI-LO all specify a 52.9-liter capacity. A HI-LO transmission incorporates a supplementary range-splitting mechanism, which accounts for the considerably larger fluid volume compared to standard manual transmission configurations in the same series.
  • All configurations across the series share a uniform check interval of 400 operating hours. In agricultural equipment, hour-based intervals are used in place of mileage because engine load and operating conditions vary widely, making elapsed time under power a more reliable service trigger.
  • The fluid change interval is set at 1,600 operating hours for all listed configurations, regardless of transmission capacity or model variant. All rows carry a normal use condition, meaning the 1,600-hour drain interval applies under standard working loads rather than elevated-stress or severe-duty cycles.
  • The 110-90 DT entered production in 1987, three years after most other 90-series models, yet shares the identical 11.7-liter capacity and 400/1,600-hour service schedule as the 100-90 and 90-90 variants introduced in 1984.
  • The 115-90, 115-90 DT, and 130-90 DT have a production window ending in 1990, making their service period shorter than the 1984-1993 span of several other configurations in the series, though the transmission specifications themselves are unchanged.
