Lexus IS, XE10 (USA / CAN)

Additional Notes

• The Lexus IS 300 XE10 automatic transmission carries a dry fill capacity of 8 liters for the 2001-2002 model year across both USA and CAN markets. Dry fill represents the total fluid volume required when filling a completely empty transmission, such as after a full rebuild or replacement, and accounts for fluid held in the torque converter and all internal passages.
• From the 2002-2003 model year onward, the dry fill capacity increased slightly to 8.2 liters across both markets, a figure that held through the 2003-2005 range. This small increase reflects a change in the transmission unit used in those later model years.
• The service fill capacity, which represents only the volume displaced during a routine drain-and-refill procedure, dropped from 2.4 liters in the 2001-2002 specification to 2.0 liters from 2002-2003 onward. The gap between the dry fill and service fill figures illustrates how much fluid remains trapped in the torque converter and valve body during a standard service, making a single drain-and-refill an incomplete fluid exchange relative to total system volume.
• For the Canadian market IS 300, the fluid check interval is set at 16,000 km across all model years from 2001-2005, with a change interval of 96,000 km under normal use conditions. Both intervals apply uniformly regardless of the capacity revision introduced at the 2002-2003 model year boundary.
• The USA market IS 300 for 2001-2002 under normal use conditions specifies only a check interval of 30,000 miles or 24 months, with no corresponding change interval listed for that condition. Under severe use conditions for the same 2001-2002 model year, a change interval of 60,000 miles or 48 months is added alongside the same 30,000-mile or 24-month check interval.
• The USA market 2002-2003 IS 300 follows the same pattern, with normal use carrying only a check interval of 30,000 miles or 24 months, while severe use adds a change interval of 60,000 miles or 48 months. The capacity revision to 8.2 liters dry fill and 2.0 liters service fill applies equally to both use conditions in that model year range.
• For the USA market 2003-2005 IS 300 under normal use, the check interval remains at 30,000 miles but the time component extends to 36 months, up from 24 months in the 2001-2003 specifications. No change interval is listed for normal use in the 2003-2005 USA configuration.
• The dual-format interval structure used in USA specifications, expressing service intervals in both mileage and calendar months, reflects a time-based trigger that activates when the mileage threshold has not been reached within the allotted period. The Canadian specifications express intervals in kilometers only, without a parallel time-based component.
