Additional Notes

  • The Subaru Baja manual transmission and transferbox combined capacity is 3.5 liters across all listed configurations, covering both the 2.5i and 2.5 Turbo variants in USA and CAN markets for their respective model year ranges.
  • A 3.5-liter figure for a combined manual transmission and transferbox fill is a relatively high capacity, reflecting that the single measurement accounts for two mechanically linked fluid chambers rather than the transmission alone.
  • Under normal use conditions, the service action specified is a fluid check at 30,000 miles or 30 months, whichever comes first, rather than a full fluid change.
  • Under severe use conditions, the interval shortens to a fluid change at 15,000 miles or 15 months, exactly half the normal-use mileage and time threshold.
  • The severe-use interval requires an actual fluid change at 15,000 miles or 15 months, whereas the normal-use interval at 30,000 miles or 30 months calls only for an inspection, making the service action itself different between the two conditions, not just the timing.
  • The 2.5i variants in both USA and CAN markets share an identical 3.5-liter capacity and the same check and change intervals as the 2.5 Turbo variants, indicating no capacity or interval differentiation between the naturally aspirated and turbocharged engines in the manual transmission system.
  • The 2.5i is listed for model years 2002-2005, while the 2.5 Turbo enters the specifications at 2004, meaning both engine variants overlap across the 2004-2005 model years within the same manual transmission fluid specifications.
  • The capacity and interval specifications are identical between the USA and CAN market versions for each respective engine variant, with no regional differentiation in the manual transmission fluid data.
