Additional Notes

  • The INFINITI EX35 J50 in both AWD and rear-wheel configurations for 2008-2010 carries a total automatic transmission fluid capacity of 10.3 liters, a figure that reflects a full overhaul or dry fill rather than a routine service drain-and-fill, which typically recovers only a fraction of total system volume.
  • The 2012-2013 EX 3.7 and EX 3.7 AWD variants share an identical automatic transmission fluid capacity of 9.2 liters, a reduction of 1.1 liters compared to the 10.3-liter figure associated with the earlier EX35 configurations.
  • The AWD and non-AWD versions of the EX35 J50 for 2008-2009 and 2009-2010 carry the same 10.3-liter capacity, indicating the drivetrain layout does not alter the transmission fluid volume requirement for those model years.
  • A fluid check interval of every 15,000 miles or 12 months, whichever comes first, is specified under normal use conditions for all EX35 J50 configurations across 2008-2010. No equivalent check interval appears in the 2012-2013 EX 3.7 rows.
  • The 15,000-mile or 12-month check interval on the EX35 J50 applies specifically under normal use conditions. Normal use generally refers to everyday driving without the elevated thermal and mechanical stress associated with severe-duty classifications such as frequent towing, extreme temperatures, or stop-and-go urban cycles.
  • The 2009-2010 EX35 and EX35 AWD entries duplicate the same capacity and interval values seen in the 2008-2009 rows, reflecting a consistent specification across the early production span of the J50 platform with the 3.5-liter engine.
