Do You Add Transmission Fluid While the Car is Running?

The Answer: Yes and No

Adding transmission fluid to your car is a relatively simple task that can be done in a few minutes. However, there is some debate about whether or not you should add transmission fluid while the car is running. Some people believe that it is necessary to add transmission fluid while the car is running in order to get an accurate reading of the fluid level. Others believe that it is not necessary and that adding transmission fluid while the car is running can actually cause damage to the transmission.

So, what is the correct answer?

The answer is that it depends on the type of transmission you have. Most modern cars have a sealed transmission, which means that the transmission fluid is not supposed to be changed. If you have a sealed transmission, you should not add transmission fluid while the car is running. Adding transmission fluid while the car is running can actually cause damage to the transmission.

However, if you have an older car with a non-sealed transmission, you may need to add transmission fluid while the car is running. This is because the transmission fluid in a non-sealed transmission can leak out over time. If you notice that your car is leaking transmission fluid, you should add transmission fluid while the car is running. This will help to prevent damage to the transmission.

Here are some tips for adding transmission fluid to your car:

1. Park your car on a level surface.
2. Turn off the engine.
3. Locate the transmission fluid dipstick.
4. Pull out the dipstick and wipe it clean with a rag.
5. Reinsert the dipstick and pull it out again.
6. Check the fluid level on the dipstick.
7. If the fluid level is low, add transmission fluid until the level is at the “Full” mark on the dipstick.
8. Reinsert the dipstick and tighten it.

Adding transmission fluid to your car is a relatively simple task that can be done in a few minutes. However, it is important to know the type of transmission you have before you add transmission fluid. If you have a sealed transmission, you should not add transmission fluid while the car is running. Adding transmission fluid while the car is running can actually cause damage to the transmission. If you have an older car with a non-sealed transmission, you may need to add transmission fluid while the car is running.
