The transmission is a vital component of your Toyota Avalon, and it requires proper maintenance to function correctly. One of the most important maintenance tasks is ensuring that the transmission has the correct amount of fluid. If the fluid level is too low, the transmission can overheat and suffer damage. Conversely, if the fluid level is too high, it can cause the transmission to slip and lose power.
Toyota Avalon Transmission Fluid Capacity
| Generation (Years) | Transmission Type(s) | Capacity (Quarts) |
|---|---|---|
| 1st Gen (1995-1999) | 4-Speed Automatic | 6 – 7 |
| 2nd Gen (2000-2004) | 4-Speed Automatic & 5-Speed Automatic | 6 – 7 (4-speed) 9 – 10 (5-speed) |
| 3rd Gen (2005-2012) | 5-Speed Automatic & 6-Speed Automatic | 6 – 7 (5-speed) 9 – 10 (6-speed) |
| 4th Gen (2013-2018) | 6-Speed Automatic | 9 – 10 |
| 5th Gen (2019-Present) | 8-speed Automatic | 9 – 10 |
Important Notes:
- Variations: Within a generation, there may be slight differences depending on the specific model year and optional packages.
- Fluid Type: Always confirm the correct fluid type required for your specific Avalon. Using the wrong fluid can cause serious damage.
- Drain & Fill vs. Flush: The listed capacity is an approximation for a drain and fill. A complete transmission flush may require more fluid.
- Owner’s Manual Supremacy: Always consult your Avalon’s owner’s manual for the most accurate and up-to-date information.
Checking the Transmission Fluid Level
To check the transmission fluid level, you will need to locate the transmission dipstick. The dipstick is usually located near the front of the engine, and it is typically marked with a red or orange handle. Once you have found the dipstick, pull it out and wipe it clean with a rag. Then reinsert the dipstick into the transmission and pull it out again.
The transmission fluid level should be between the two marks on the dipstick. If the fluid level is below the lower mark, you will need to add fluid. If the fluid level is above the upper mark, you will need to drain some fluid.
Adding Transmission Fluid
To add transmission fluid, you will need a funnel and a quart of the correct type of fluid. You can find the correct type of fluid in your owner’s manual. Once you have the funnel and fluid, follow these steps:
- Locate the transmission fluid filler tube. The filler tube is usually located near the top of the transmission, and it is typically marked with a blue or green cap.
- Insert the funnel into the filler tube.
- Pour the transmission fluid into the funnel.
- Once you have added the correct amount of fluid, replace the cap on the filler tube.
Draining Transmission Fluid
To drain transmission fluid, you will need a drain pan and a wrench. Once you have the drain pan and wrench, follow these steps:
- Locate the transmission fluid drain plug. The drain plug is usually located at the bottom of the transmission, and it is typically marked with a 17mm bolt.
- Place the drain pan under the drain plug.
- Use the wrench to loosen the drain plug.
- Allow the transmission fluid to drain into the pan.
- Once the transmission fluid has drained, replace the drain plug.
Changing the Transmission Fluid
It is recommended that you change the transmission fluid every 30,000 to 60,000 miles. However, you may need to change the fluid more often if you drive in severe conditions, such as stop-and-go traffic or towing heavy loads.
To change the transmission fluid, you will need a new transmission filter, a new transmission fluid pan gasket, and 4 to 5 quarts of the correct type of fluid. You can find the correct type of fluid in your owner’s manual. Once you have the necessary parts and fluids, follow these steps:
- Remove the transmission fluid pan. The transmission fluid pan is usually held in place by bolts.
- Replace the transmission filter. The transmission filter is usually located inside the transmission fluid pan.
- Replace the transmission fluid pan gasket. The transmission fluid pan gasket is a thin rubber gasket that seals the transmission fluid pan to the transmission.
- Reinstall the transmission fluid pan.
- Add the correct amount of transmission fluid.
Conclusion
Checking, adding, draining, and changing the transmission fluid are all essential maintenance tasks that can help extend the life of your Toyota Avalon transmission. By following the steps outlined in this blog post, you can ensure that your transmission has the correct amount of fluid and is functioning correctly. Regular maintenance of the transmission fluid can prevent potential issues and ensure smooth operation of your Toyota Avalon, providing you with peace of mind and a reliable driving experience.
