Change or Flush Car Automatic Transmission Fluid in an Avalon
Introduction
The automatic transmission in your Avalon is a complex and vital part of your vehicle. It is responsible for transferring power from the engine to the wheels, and it also helps to keep the engine running smoothly. The transmission fluid is a special type of oil that helps to lubricate the transmission and protect it from wear and tear. Over time, the transmission fluid can become contaminated with metal shavings, dirt, and other debris. This can lead to problems with the transmission, such as slipping, shuddering, or even complete failure.
It is important to have the transmission fluid changed or flushed on a regular basis to help keep the transmission in good condition. The frequency with which you need to service the transmission will vary depending on your driving habits and the type of transmission in your Avalon. However, most experts recommend having the transmission fluid changed or flushed every 30,000 to 60,000 miles.
What are the Signs that Transmission Fluid Needs to be Changed?
There are several signs that may indicate that your transmission fluid needs to be changed. These include:
- Slipping gears
- Shuddering when shifting gears
- Difficulty shifting gears
- Leaking transmission fluid
- Dark or burnt-smelling transmission fluid
How to Change the Transmission Fluid
Changing the transmission fluid is a relatively simple process that can be done at home with a few basic tools. Here are the steps on how to do it:
- Gather your materials. You will need:
- New transmission fluid (check your owner’s manual for the correct type and amount)
- Transmission filter (if applicable)
- Drain pan
- Funnel
- Wrench or socket set
- Park your Avalon on a level surface and engage the parking brake.
- Locate the transmission fluid drain plug. It is usually located on the bottom of the transmission pan.
- Place the drain pan under the drain plug and loosen the plug with a wrench or socket.
- Allow the transmission fluid to drain completely into the drain pan.
- Replace the drain plug and tighten it to the specified torque.
- Locate the transmission fluid filter. It is usually located on the side of the transmission pan.
- Remove the filter and replace it with a new one.
- Reinstall the transmission pan and tighten the bolts to the specified torque.
- Add new transmission fluid to the transmission through the dipstick tube. Use a funnel to prevent spills.
- Check the transmission fluid level and add more fluid as needed.
- Start the engine and allow it to idle for a few minutes.
- Shift through all of the gears and check for any leaks.
How to Flush the Transmission Fluid
Flushing the transmission fluid is a more thorough process than simply changing the fluid. It involves using a special machine to circulate new fluid through the transmission to remove contaminants. Flushing the transmission fluid is more expensive than changing the fluid, but it can be more effective in removing contaminants and extending the life of the transmission.
To flush the transmission fluid, you will need to take your Avalon to a mechanic. The mechanic will use a special machine to connect to the transmission and circulate new fluid through the system. The flushing process usually takes about an hour.
Conclusion
Changing or flushing the transmission fluid in your Avalon is an important part of maintaining your vehicle. By following the steps outlined above, you can help to keep your transmission in good condition and extend its life.
