Lexus GS, XL10 (EU)

Additional Notes

• The Lexus GS-F (2015-2019) carries the largest automatic transmission dry fill capacity across all listed variants at 11.2 liters, reflecting the greater fluid volume demanded by the high-displacement V8 drivetrain. Service fill for the same variant is 3.7 liters, which represents only the fluid replaced during a routine drain-and-fill without disassembly of the torque converter.
• The GS 350 across both its 2012-2015 and 2015-2019 model year ranges shares an identical set of capacity figures: 10 liters dry fill, 1.6 liters service fill, 4.9 liters for the torque converter, and 3.8 liters for the transmission valve body. The service fill of 1.6 liters is notably low relative to the dry fill, indicating that a standard drain recovers a small proportion of total system fluid.
• The GS 250 (2012-2015) has the smallest service fill capacity of all listed variants at 1.4 liters, paired with a dry fill of 7.5 liters. The wide gap between these two figures underscores how much fluid remains trapped in the torque converter and valve body during a conventional service drain.
• The GS 200t (2015-2017) and GS 300 (2017-2019) share the same capacity values across all four fill categories: 8.7 liters dry fill, 3.2 liters service fill, 6.5 liters torque converter, and 4.0 liters transmission valve body. Both variants use the same transmission unit, which accounts for the identical specifications.
• Torque converter capacity figures vary considerably across the lineup. The GS 250 lists 4.0 liters, the GS 200t and GS 300 list 6.5 liters, the GS 350 lists 4.9 liters, and the GS-F lists 6.7 liters. Torque converter capacity is a separate sub-volume within the total dry fill and is relevant primarily during a full transmission overhaul or converter replacement.
• Under normal use conditions, all listed variants share the same check interval: 48 months or 60,000 km, whichever comes first. No fluid change interval is specified for normal use, meaning the schedule calls only for a fluid condition check at that point.
• Under severe use conditions, all variants require a fluid check at 36 months or 45,000 km, followed by a change at 72 months or 90,000 km. The addition of a mandatory change interval under severe conditions, absent from the normal use schedule, reflects the accelerated fluid degradation associated with more demanding operating environments.
• The transmission valve body capacity for the GS-F is 4.7 liters, the highest among all listed variants. By comparison, the GS 250 lists 2.5 liters for the same component. Valve body capacity figures are relevant when the valve body assembly is removed and refilled independently during transmission servicing.
