GM Vehicle Care: Automatic Transmission Fluid
What is Automatic Transmission Fluid?
Automatic transmission fluid (ATF) is a specialized fluid used in automatic transmissions to lubricate, cool, and clean the transmission components. It is a highly engineered fluid that contains a variety of additives to perform these functions.
Why is ATF Important?
ATF is essential for the proper operation of an automatic transmission. It helps to:
* Lubricate the transmission components, reducing friction and wear
* Cool the transmission components, preventing overheating
* Clean the transmission components, removing metal shavings and other debris
* Prevent corrosion, rust, and foaming in the transmission
When Should I Change My ATF?
The recommended interval for changing ATF varies depending on the make and model of your GM vehicle. However, most manufacturers recommend changing the ATF every 30,000 to 50,000 miles. If you tow heavy loads or drive in severe conditions, you may need to change your ATF more frequently.
What Type of ATF Should I Use?
It is important to use the correct type of ATF for your GM vehicle. Using the wrong type of ATF can damage your transmission. The type of ATF recommended for your vehicle will be listed in your owner’s manual.
How to Change ATF
Changing ATF is a relatively simple procedure that can be done at home with the right tools and materials. However, if you are not comfortable working on your vehicle, you can have it done by a qualified mechanic.
To change ATF, you will need:
* New ATF
* A new ATF filter
* A drain pan
* A funnel
* A wrench
* A screwdriver
1. Park your vehicle on a level surface and engage the parking brake.
2. Locate the transmission drain plug and place the drain pan beneath it.
3. Use the wrench to loosen the drain plug and allow the ATF to drain into the pan.
4. Once the ATF has stopped draining, remove the drain plug and replace it with the new one.
5. Locate the transmission filter and remove it.
6. Install the new filter in place of the old one.
7. Use the funnel to add new ATF to the transmission.
8. Check the ATF level and add more as needed until it reaches the full mark.
9. Start your vehicle and let it idle for a few minutes.
10. Shift the transmission through all the gears and then check the ATF level again. Add more ATF as needed until it reaches the full mark.
Tips for Maintaining Your ATF
Here are a few tips for maintaining your ATF and keeping your transmission running smoothly:
* Check the ATF level regularly and add more as needed.
* Change the ATF according to the recommended interval.
* Use the correct type of ATF for your vehicle.
* Avoid towing heavy loads or driving in severe conditions if possible.
* If you notice any leaks or problems with your transmission, have it inspected by a qualified mechanic as soon as possible.
By following these tips, you can help to extend the life of your transmission and keep your GM vehicle running smoothly for years to come.
