Additional Notes

  • The Subaru Tribeca (B9) (EU) automatic transmission holds 9.8 liters across all model year ranges covered in the specifications, from 2006 through 2014.
  • A 9.8-liter capacity is consistent with a full transmission overhaul or dry fill figure, accounting for fluid held in the torque converter, valve body, and transmission pan combined.
  • For the 2006-2008 model years under normal use conditions, both a check interval and a change interval are specified, with the check set at 30,000 km or 24 months and the fluid change due at 60,000 km or 48 months.
  • Starting with the 2008-2011 range, the normal use specification no longer carries a dedicated change interval, listing only a check at 48,000 km or 30 months.
  • The 2008-2011 severe use condition introduces a fluid change interval of 24,000 km or 15 months, which is half the distance of the 60,000 km change interval listed for the earlier 2006-2008 normal use schedule.
  • The 2011-2014 specifications mirror the 2008-2011 structure exactly, with normal use carrying a check at 48,000 km or 30 months and severe use requiring a fluid change at 24,000 km or 15 months.
  • The severe use change interval of 24,000 km or 15 months applies to both the 2008-2011 and 2011-2014 ranges, indicating a consistent threshold for demanding operating conditions across those generations.
  • The shift from a combined check-and-change schedule in 2006-2008 to a check-only normal use schedule from 2008 onward represents a structural difference in how service intervals are expressed across the model's production span.
