How much transmission fluid does a GX470 use?
The GX470’s automatic transmission typically requires about 11 to 12 quarts of ATF for a pan drop with a new filter, and roughly 12 to 14 quarts if you’re performing a full system drain and fill or flush. Exact amounts can vary by model year and service method.
GX470 transmission basics
The Lexus GX470, produced from 2003 to 2009, uses a 5-speed automatic transmission (A750E) paired with the 4.7-liter 2UZ-FE V8. Transmission fluid capacity isn’t a single fixed number; it depends on whether you’re draining only the pan, replacing the filter, or performing a full system flush that also moves fluid through the torque converter and cooler lines. For accurate service, consult the specific year’s service data or the owner’s manual.
Fluid capacity by service type
Below are typical capacities you’ll encounter during common GX470 transmission services. The figures assume standard factory fluid and recommended filters; actual amounts can vary slightly by year and exact transmission configuration. The numbers include the fluid needed to fill the system after servicing.
- Pan drain with filter replacement (simple service): about 11 to 12 quarts (10.5 to 11.5 liters).
- Full system drain and fill or flush (includes torque converter and cooler lines): about 12 to 14 quarts (11.4 to 13.2 liters).
When planning a transmission service, the method you choose affects the total fluid required. Some shops perform a torque-converter drain and a more aggressive flush, which can push the total toward the upper end of the range. Always verify the exact capacity for your model year in the service manual or with a Lexus/Toyota dealership.
Notes on accuracy and variations
Capacities can vary slightly by year, transmission revision, or if your GX470 has any factory upgrades or aftermarket components. If you’re performing service yourself, it’s prudent to have extra ATF on hand (a quart or two above the expected total) to account for valve-body differences and to ensure the system reaches the proper full level when hot.
Summary
For routine maintenance on a GX470, plan for about 11–12 quarts of ATF for a pan drop with a new filter, and 12–14 quarts for a full system drain and fill or flush. Always confirm the exact specification for your vehicle’s year and transmission configuration in the official service data or with a dealer.
Additional tip
Check the transmission fluid level with the engine warmed up and running, in Park, with the transmission at operating temperature, and the level measured on the dipstick per the service manual instructions to ensure accurate results after a fill.
