Additional Notes

  • The Lexus SC 430 (Z40, EU) automatic transmission carries a dry fill capacity of 8.9 liters, a figure that reflects the total fluid volume required when the transmission is fully drained and reassembled, such as after an overhaul or complete unit replacement.
  • The service fill capacity is 1.8 liters across all SC 430 model year ranges covered, representing the much smaller volume exchanged during a routine fluid service where residual fluid remains in the torque converter and passages.
  • The gap between the 8.9-liter dry fill and the 1.8-liter service fill illustrates how a standard drain-and-fill procedure replaces only a fraction of the total fluid volume in the transmission.
  • For the 2001-2005 SC 430 under normal use conditions, the specification calls for a fluid check at 45,000 km or 36 months, with no separate change interval listed for normal use.
  • Under severe use conditions across the 2001-2005 SC 430 ranges, a fluid change is specified at 90,000 km or 72 months, in addition to the same 45,000 km / 36-month check interval shared with normal use.
  • The 2005-2010 SC 430 under normal use conditions carries a revised check interval of 60,000 km or 48 months, which is longer than the 45,000 km / 36-month check interval applied to earlier model year ranges under the same use condition.
  • Under severe use conditions, the 2005-2010 SC 430 retains the 45,000 km / 36-month check interval and the 90,000 km / 72-month change interval, aligning with the severe-use schedule applied to all earlier SC 430 ranges.
