When to Change Car Automatic Transmission Fluid
Introduction
Automatic transmission fluid (ATF) is a vital fluid in your car’s transmission. It lubricates the moving parts, helps to cool the transmission, and prevents wear and tear. Over time, ATF can become contaminated with metal shavings, dirt, and other debris. This can cause the transmission to slip, shudder, or even fail.
How Often Should You Change ATF?
The frequency with which you need to change ATF depends on several factors, including the type of transmission you have, your driving habits, and the climate you live in.
* Conventional ATF: Most conventional ATFs should be changed every 30,000 to 60,000 miles.
* Synthetic ATF: Synthetic ATFs are more durable and can typically last longer than conventional ATFs. Some synthetic ATFs are designed to last up to 100,000 miles or more.
* Severe driving conditions: If you drive in stop-and-go traffic, tow heavy loads, or live in a hot climate, you may need to change ATF more often.
Signs That It’s Time to Change ATF
There are several signs that indicate it’s time to change ATF, including:
* Slipping gears: If your transmission slips gears, it could be a sign that the ATF is low or contaminated.
* Shuddering: If your transmission shudders when you shift gears, it could be a sign that the ATF is old or dirty.
* Leaking ATF: If you see ATF leaking from your transmission, it’s important to have it checked by a mechanic.
* Dark or burnt ATF: If your ATF is dark or burnt, it’s a sign that it’s time to change it.
How to Change ATF
Changing ATF is a relatively simple process that can be done at home with the right tools and materials.
1. Gather your materials. You will need:
* New ATF (check your owner’s manual for the correct type and amount)
* A new ATF filter
* A drain pan
* A funnel
* A wrench
2. Locate the transmission pan. The transmission pan is usually located on the bottom of the transmission. It is held in place by bolts.
3. Drain the old ATF. Place the drain pan under the transmission pan and remove the bolts. Allow the old ATF to drain into the pan.
4. Replace the ATF filter. Remove the old ATF filter and replace it with a new one.
5. Reinstall the transmission pan. Once the new ATF filter is in place, reinstall the transmission pan and tighten the bolts.
6. Add new ATF. Use the funnel to add new ATF to the transmission. Add the amount specified in your owner’s manual.
7. Check the ATF level. Start the engine and let it run for a few minutes. Then, check the ATF level using the dipstick. The ATF level should be between the “full” and “add” marks on the dipstick.
Conclusion
Changing ATF is an important part of maintaining your car’s transmission. By following the guidelines in this article, you can help to extend the life of your transmission and keep your car running smoothly.
