How many quarts of transmission fluid does a 2004 Toyota Avalon take?
Approximately 11 quarts for a full system fill, with typical service needing about 9–10 quarts; the exact amount depends on the service method and the specific transmission model installed in the car.
The 2004 Avalon's automatic transmission capacity can vary slightly by model and production details, and fluid needs are influenced by whether you’re performing a pan-drop/filter change, a partial drain, or a full transmission flush. For the most precise figure, consult the owner’s manual or contact a Toyota service department with your VIN.
Capacity by service method
Below are common capacity figures for the 2004 Avalon when serviced using typical methods. These reflect common scenarios for the generation that year (V6 engine with an automatic transmission) and may vary by exact transmission code.
- Total system capacity (including torque converter): about 11–12 quarts.
- Pan-drop and filter-change capacity: about 9–10 quarts.
- Full transmission flush capacity (machine service): about 12 quarts.
Because some fluid remains in the torque converter and in other internal passages, the actual amount you end up using can vary by a pint or two from these figures. Always verify by checking the transmission fluid level after service, once the transmission reaches its proper operating temperature and the level is stabilized.
Factors that can affect the exact capacity
Key variables include the specific transmission model code used in your 2004 Avalon, engine combination, and production run. While many Avalons that year share a similar automatic transmission design, VIN-specific specifications can differ enough to change the precise fill amount. When in doubt, refer to the official Toyota maintenance data for your vehicle.
Practical guidance for service planning
If you’re planning a service, prepare fluids and tools with the understanding that a full fill will require roughly 11–12 quarts, while a standard pan drop and filter change will use about 9–10 quarts. If you’re performing a full flush, have around 12 quarts available to account for all steps and potential variations in fluid recovery.
Summary: For a 2004 Toyota Avalon, target around 11 quarts for a complete fill, with a general range of 9–12 quarts depending on the service method and transmission specifics. Verify exact capacity for your vehicle using the owner’s manual or a Toyota dealership.
Summary
In short, plan for roughly 11 quarts for a full system fill on a 2004 Avalon, with 9–10 quarts typical for a pan-drop/filter service and about 12 quarts for a full flush. Always confirm the exact figure for your VIN and ensure proper fill levels after service. Regular checks help ensure smooth shifting and transmission longevity.
How many quarts of transmission fluid does a Toyota Avalon take?
The Toyota Avalon's transmission fluid capacity varies by model year and transmission type. For a 2005-2006 model with a U151E transmission, the total fill is approximately 9.3 quarts. For a 2017 model with a U660E 6-speed transmission, the total fill is about 6.9 quarts, while a 2018-2022 hybrid model requires around 3.9 quarts.
| Year(s) | Transmission Type | Total Fill Capacity |
|---|---|---|
| 2005-2006 | U151E (5-speed) | ~9.3 quarts |
| 2017 | U660E (6-speed) | ~6.9 quarts |
| 2018-2022 (Hybrid) | Hybrid transmission | ~3.9 quarts |

- For drain-and-fill: The amount of fluid needed will be less than the total capacity because not all the fluid is drained, especially from the torque converter. For a typical drain and fill on a 2005-2006 model, you can expect to need around 3.7 to 4 quarts.
- For a full fluid exchange: The total capacity listed above is what is needed for a complete refill after the torque converter and all internal components have been drained.
- Fluid Type: Always use Toyota ATF WS fluid, or a high-quality equivalent, for your Avalon's transmission.
- Filling Process: For transmissions without a dipstick, add the new fluid through the fill plug until it begins to trickle out of the overflow plug, and check the final level once the transmission has reached a warm temperature (approximately 104−113104 minus 113104−113 °F).
How much transmission fluid does a 2004 Toyota Avalon take?
The 2004 Toyota Avalon's transmission fluid capacity is approximately 7.5 to 8 quarts for a full drain and fill, though an initial fill requires about 4.7 to 5 quarts. The correct fluid type for this model is Toyota WS (World Standard) or an equivalent that meets specifications like Dexron III.

Full drain and fill
- Capacity: Approximately 7.5 to 8 quarts
- Important: This includes the fluid in the torque converter, which is only drained during a full service
Initial fill
- Capacity: Approximately 4.7 to 5 quarts
- Important: This is the amount needed if you are not draining the torque converter
Fluid type
- Primary recommendation: Toyota WS (World Standard) automatic transmission fluid
- Alternative: An equivalent fluid meeting Dexron III specifications is also acceptable
What transmission fluid does a Toyota Avalon take?
The correct Toyota Avalon transmission fluid type depends on the model year, with newer models typically using Toyota WS (World Standard) fluid and older models often requiring Dexron III or other specified fluids. Always consult your owner's manual for the specific type, as using the incorrect fluid can damage the transmission. For example, the 2004 model may use Dexron VI, while a 2006 model may use WS fluid.
- For newer models: Look for fluids that meet the Toyota WS specification.
- For older models: Check your owner's manual, as it may specify fluids like Dexron III or Dexron VI.
- To be sure: Always refer to your vehicle's owner's manual to confirm the exact fluid type required for your specific year and model.
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.
