## When to Change Car Automatic Transmission Fluid

Automatic transmission fluid (ATF) is a vital part of your car’s transmission system. It lubricates the moving parts of the transmission, helps to cool the system, and transmits power from the engine to the wheels. Over time, ATF can break down and become contaminated with metal shavings, dirt, and other debris. This can lead to transmission problems, such as slipping gears, shuddering, and difficulty shifting.

There is no definitive answer to the question of how often you should change your ATF. However, most manufacturers recommend changing it every 30,000 to 60,000 miles. If you drive in stop-and-go traffic or tow heavy loads, you may need to change your ATF more frequently.

Here are some signs that you may need to change your ATF:

Slipping gears: This is one of the most common symptoms of low or dirty ATF. If your car is slipping gears, it is important to have the ATF checked and changed as soon as possible.
Shuddering: Shuddering is another common symptom of low or dirty ATF. This can occur when you accelerate or decelerate, or when you shift gears.
Difficulty shifting: If you are having difficulty shifting gears, it may be a sign that your ATF is low or dirty.
Leaking ATF: If you notice a leak in your transmission, it is important to have it checked out by a mechanic as soon as possible. A leak can lead to low ATF levels and transmission problems.

If you are experiencing any of these symptoms, it is important to have your ATF checked and changed as soon as possible. Changing your ATF is a relatively simple and inexpensive procedure that can help to prevent transmission problems and extend the life of your car.

## How to Check Your ATF Level

Checking your ATF level is a simple process that you can do yourself. Here are the steps:

1. Park your car on a level surface.
2. Turn off the engine and allow it to cool down.
3. Open the hood and locate the transmission dipstick. The dipstick is usually located near the front of the engine, and it will have a red or orange handle.
4. Pull out the dipstick and wipe it clean with a rag.
5. Reinsert the dipstick all the way into the transmission.
6. Pull the dipstick out again and check the ATF level. The ATF level should be between the “min” and “max” marks on the dipstick.

If the ATF level is low, you will need to add more ATF. Be sure to use the type of ATF that is recommended by your car’s manufacturer.

## How to Change Your ATF

Changing your ATF is a relatively simple procedure that you can do yourself with a few basic tools. Here are the steps:

1. Gather your materials. You will need the following:
New ATF (use the type that is recommended by your car’s manufacturer)
A funnel
A wrench
A drain pan
Rags
2. Park your car on a level surface and turn off the engine.
3. Locate the transmission drain plug. The drain plug is usually located on the bottom of the transmission pan.
4. Place the drain pan under the drain plug.
5. Use the wrench to loosen the drain plug. Be careful not to drop the drain plug into the pan.
6. Allow the ATF to drain out of the transmission. This may take a few minutes.
7. Once the ATF has drained out, tighten the drain plug.
8. Locate the transmission fill plug. The fill plug is usually located on the side of the transmission pan.
9. Insert the funnel into the fill plug.
10. Add new ATF to the transmission. Add enough ATF until the level reaches the “max” mark on the dipstick.
11. Remove the funnel and tighten the fill plug.
12. Start the engine and check for leaks.

If you are not comfortable changing your ATF yourself, you can have it done by a mechanic.

## Benefits of Changing Your ATF

Changing your ATF can provide a number of benefits, including:

Improved transmission performance: New ATF will help to lubricate the moving parts of the transmission and reduce friction. This can lead to smoother shifting and improved performance.
Extended transmission life: Changing your ATF regularly can help to extend the life of your transmission by preventing wear and tear.
Reduced repair costs: Changing your ATF can help to prevent transmission problems, which can save you money on repairs in the long run.

## Conclusion

Changing your car’s ATF is a simple and inexpensive procedure that can help to prevent transmission problems and extend the life of your car. If you are experiencing any of the symptoms of low or dirty ATF, it is important to have your ATF checked and changed as soon as possible.
