Additional Notes

  • The Toyota Hilux N140/N150/N160/N170 (EU) 2.5 D4-D 90 2WD automatic transmission carries a dry fill capacity of 10.1 liters, which represents the total fluid volume required when filling a completely drained or rebuilt unit, such as after a full overhaul or replacement.
  • The service fill capacity is 2 liters across all listed configurations, reflecting the smaller volume exchanged during a routine fluid change where residual fluid remains in the torque converter and passages.
  • The gap between the 10.1-liter dry fill and the 2-liter service fill is substantial, indicating that a standard drain-and-fill procedure replaces only a fraction of the total fluid volume held in the transmission system.
  • Under normal use conditions, the automatic transmission fluid check interval is set at 45,000 km or 36 months, with a change interval of 90,000 km or 72 months, for both the 2001-2003 and 2003-2005 production periods.
  • Under severe use conditions, the check interval shortens to 22,500 km or 18 months, and the change interval is reduced to 45,000 km or 36 months, exactly half the normal-use figures in both distance and time.
  • The 2001-2003 and 2003-2005 variants of the Hilux 2.5 D4-D 90 2WD share identical capacity and interval specifications across both normal and severe use conditions, indicating no revision to automatic transmission service requirements between those two production periods.
