Do You Check Transmission Fluid While Car Running?
Introduction
Checking transmission fluid is an important part of maintaining your vehicle. It helps ensure that your transmission is operating properly and efficiently. But when should you check it? And does it matter if your car is running or not?
When to Check Transmission Fluid
The best time to check transmission fluid is when the engine is running and the transmission is in park. This is because the fluid circulates through the transmission when the engine is running, and checking it in park will give you the most accurate reading.
However, you can also check transmission fluid when the engine is not running. Just be aware that the reading may not be as accurate.
How to Check Transmission Fluid
To check transmission fluid, you will need:
- A clean rag
- A flashlight
Once you have these items, follow these steps:
- Locate the transmission dipstick. It is usually located on the side of the transmission or near the engine.
- Pull out the dipstick and wipe it clean with the rag.
- Reinsert the dipstick all the way into the transmission.
- Pull out the dipstick again and check the fluid level. It should be between the “full” and “add” marks on the dipstick.
- If the fluid level is low, add some transmission fluid through the dipstick tube.
Checking Transmission Fluid While Car Running
As mentioned earlier, it is best to check transmission fluid when the engine is running. This is because the fluid circulates through the transmission when the engine is running, and checking it in park will give you the most accurate reading.
However, if you need to check the transmission fluid while the car is not running, you can do so. Just be aware that the reading may not be as accurate.
To check transmission fluid while the car is not running, follow these steps:
- Park the car on a level surface.
- Turn off the engine.
- Wait a few minutes for the fluid to settle.
- Check the transmission fluid level using the steps outlined above.
Conclusion
Checking transmission fluid is an important part of maintaining your vehicle. It is best to check it when the engine is running and the transmission is in park. However, you can also check it when the engine is not running, but be aware that the reading may not be as accurate.
