Do You Check Transmission Fluid Level with Car Running?

No, you should not check the transmission fluid level with the car running.

Checking the transmission fluid level with the car running can be dangerous. The transmission fluid is hot and under pressure, and it can spray out if the dipstick is removed while the car is running. It is also important to note that the transmission fluid level can vary depending on the temperature of the fluid. As a result, it is best to check the transmission fluid level when the car is cold.

Here are the steps on how to check the transmission fluid level:

1. Park the car on a level surface.
2. Turn off the engine and allow the car to cool down for a few minutes.
3. Locate the transmission fluid dipstick. The dipstick is usually located on the side of the transmission or on the back of the engine.
4. Pull out the dipstick and wipe it clean with a rag.
5. Reinsert the dipstick into the transmission and push it all the way in.
6. Pull out the dipstick again and check the fluid level. The fluid level should be between the “full” and “add” marks on the dipstick.
7. If the fluid level is low, add more transmission fluid until the level is between the “full” and “add” marks.

It is important to check the transmission fluid level regularly, as low transmission fluid can cause the transmission to overheat and fail.

If you are not comfortable checking the transmission fluid level yourself, you can take your car to a mechanic for a transmission fluid change. A mechanic can also check the transmission fluid level for you.
