How much transmission fluid does a GX470 take?

The GX470’s automatic transmission typically requires about 12 quarts (roughly 11–12 liters) for a standard drain-and-fill, and around 14–15 quarts (13–14 liters) for a full fluid replacement or flush.

The GX470 uses a 5-speed automatic transmission paired with the 4.7L V8 engine. Total capacity varies with service method (drain-and-fill vs. complete replacement) and whether the torque converter is included in the exchange. For the exact amount for your specific year and VIN, consult the owner's manual or a Lexus/Toyota service representative.

Capacity considerations and service notes

In practice, plan for roughly 12 quarts for a routine drain-and-fill and about 14–15 quarts for a full fluid change. Exact figures can differ by model year and whether the torque converter is included in the exchange, so checking the official specifications for your vehicle is advisable.

Recommended transmission fluid

Use the ATF specified by Lexus for the GX470. Most sources align with Toyota/Lexus ATF WS (World Standard); Dexron VI-compatible ATFs are commonly accepted as well. Always verify the correct fluid type for your specific year and VIN with the owner's manual or a dealership to ensure optimal shifting and longevity.

Maintenance tips

When servicing, consider replacing the transmission filter if equipped and using a new pan drain plug washer if required. After the service, recheck the level at the correct operating temperature and perform a test drive to confirm smooth shifting and proper fluid level.

Summary: For a GX470, expect about 12 quarts for a drain-and-fill and roughly 14–15 quarts for a full flush, with the exact amount depending on year, VIN, and whether the torque converter is included. Use the recommended ATF (typically Lexus/Toyota ATF WS or a Dexron VI‑compatible fluid) and verify per official specifications.

How many quarts of transmission fluid do I need for a drain and fill?

For a standard transmission fluid drain and fill, you'll typically need 3 to 5 quarts, but you should always measure the amount you drained and refill with the same amount to start, then check the level using the dipstick after running the engine. The exact amount varies by vehicle, and it's crucial to check the owner's manual or look up specifications for your specific make and model, as a drain and fill will not replace all the old fluid. 
How to determine the right amount

• Drain the old fluid: Let the old fluid drain completely. 
• Measure the drained fluid: Measure how much fluid was drained. This is your starting point for refilling. 
• Refill with the measured amount: Put the same amount of new, correct transmission fluid back into the transmission. Using a funnel can help with this process. 
• Start the engine: Start the vehicle and let it run for a few minutes, shifting through all the gears (Park, Reverse, Neutral, Drive) while holding the brake. This circulates the new fluid. 
• Check the level: Turn the engine off and check the fluid level with the dipstick. Add more fluid in small increments if the level is low, or drain a small amount if it's too high. 
• Re-check: Repeat the process of running the engine and checking the dipstick until the fluid level is correct according to the dipstick's hash marks for a "hot" reading. 

Important considerations

• A drain and fill is different from a full transmission flush, which requires significantly more fluid (10-12 quarts or more) because it aims to replace all the fluid, including what's in the torque converter. 
• You should always use the specific type of transmission fluid recommended by your vehicle's manufacturer to avoid damage. 
• Some vehicles, like certain Land Rovers, do not have a dipstick and require a fluid extractor to add new fluid. Consult your owner's manual to be certain.
