How many quarts of transmission fluid does a 2005 Toyota Avalon take?
About 11 quarts for a standard drain-and-fill; roughly 12 quarts if performing a full transmission flush.
For context, the 2005 Avalon uses a conventional four-speed automatic transmission. ATF capacity can vary slightly depending on the exact transmission variant, whether the filter is replaced, and the service method used. This article outlines typical capacities and best maintenance practices.
Understanding the capacity figures
The numbers below reflect common service guidelines cited by Toyota manuals and automotive technicians. They are intended as practical references for planning maintenance and ordering fluid.
Variations that affect the numbers
Actual capacity can vary by transmission variant, whether the filter is replaced, and whether you perform a pan-only drain or a full flush that circulates through the cooler and torque converter. Always confirm with the owner's manual or a Toyota service bulletin for your exact VIN.
ATF capacity by service type
Before listing the typical capacities, note that actual amounts depend on whether you drain and fill only the pan or perform a complete flush that circulates through the cooler and torque converter. The following figures are approximate ranges used by technicians.
- Drain and fill (pan drop with filter replacement): about 11 quarts
- Full transmission flush (including cooler lines and torque converter where applicable): around 12 quarts
In practice, you may not pour the entire listed capacity at once. The level should be checked warm on a hot engine and corrected to the full mark on the ATF dipstick as you add fluid.
Service steps if you’re performing the maintenance yourself
Below is a typical sequence used by home mechanics and some shops. The goal is to replace the fluid safely and avoid overfilling, which can cause foaming and leaks.
- Warm up the transmission by driving short distances, then let it cool before draining.
- Raise and support the vehicle securely; place a drain pan beneath the transmission pan.
- Remove the transmission pan bolts, drain old ATF, and inspect the pan and magnet for debris.
- Replace the transmission filter (if equipped) and reseal the pan with a new gasket.
- Reinstall the pan and refill with the recommended ATF to the initial level, usually a little under the full capacity to start.
- Run the engine, move through each gear with the brake held, and recheck the level hot; top off as needed to the correct mark.
- Check for leaks and take a short road test if safe; recheck level after cooling down.
Always refer to the owner’s manual or a Toyota dealer for the exact capacities for your VIN and transmission variant, and use the correct ATF specification (Toyota WS or equivalent) as recommended by Toyota.
Summary
In short, plan on about 11 quarts for a drain-and-fill, and roughly 12 quarts for a full flush on a 2005 Toyota Avalon with the common 4-speed automatic. Actual volumes can vary slightly, so verify with the service manual or a trusted mechanic and always check the level with the dipstick after warming the transmission.
How many quarts of transmission fluid do I need for a drain and fill?
You will need approximately 3-6 quarts of transmission fluid for a drain and fill, but the exact amount depends on your vehicle, so it's best to measure how much you drain out and replace that amount. Always check your owner's manual for the correct type and amount of fluid for your specific make and model.
Before you begin
- Check your owner's manual to find the specific type of transmission fluid your vehicle requires.
- You can also get this information from an auto parts store, such as AutoZone.
- Purchase enough fluid for the job, plus a little extra in case of spills or to have on hand for future top-offs.
During the procedure
- Drain the old fluid: Place a catch pan under the transmission's drain plug and remove the plug to let the old fluid drain out.
- Measure the drained fluid: Measure the amount of fluid you collected in the pan. This will be the amount you need to add back into the transmission.
- Refill the transmission: Pour the new, correct type of fluid into the transmission through the fill tube. Start with the amount you just measured.
- Check the level: After refilling, start the engine and let it run for a few minutes. Check the dipstick to see if the fluid level is correct. You may need to add a little more or less to reach the "full" mark.
