How much transmission fluid does a 2013 Lexus GX 460 hold?
The 2013 Lexus GX 460’s automatic transmission holds about 11.5 to 12 quarts of ATF in total. A standard pan drain and refill typically replaces about 7 to 9 quarts, depending on how much fluid remains in the torque converter and cooler lines. Use the Toyota/Lexus ATF WS fluid specification for maintenance.
Capacity overview
Understanding the numbers helps when planning a transmission service on the GX 460. The figures below refer to common service scenarios and may vary slightly by vehicle and service history.
- Total transmission fluid capacity: Approximately 11.5–12 quarts (about 10.9–11.4 liters) when performing a full drain that includes the torque converter and cooler lines.
- Pan drain and refill capacity (no torque converter drain): Roughly 7–9 quarts (about 6.6–8.5 liters).
- With filter replacement: The full-capacity figures assume replacement of the transmission filter; if the filter is not replaced, initial fill may be slightly less.
In practice, technicians often plan for around a dozen quarts to complete a thorough service with a new filter, plus a buffer for minor spills or top-offs after road testing.
Fluid type and service tips
Use Toyota/Lexus ATF WS (World Standard) fluid as recommended. Do not mix ATFs unless explicitly approved by Lexus. If you’re doing the service yourself, ensure the engine is warm, drain the pan, replace the filter and gasket, reinstall the pan, and refill gradually to the specified level. For models with sealed transmissions or uncertain dipstick readings, rely on the service procedure outlined in the owner’s manual or consult a dealership or qualified mechanic.
Summary
For a 2013 GX 460, plan for about 11.5–12 quarts of ATF for a full transmission service that includes the torque converter, and about 7–9 quarts for a simple pan drain and refill. Use ATF WS and follow the official service procedure. Always verify with the vehicle’s manual or a Lexus service technician to account for any model-specific variations.
