Do You Leave Your Car Running to Check Transmission Fluid?

The Answer: No

Never leave your car running to check the transmission fluid. This is because the transmission fluid level can change when the car is running. The fluid level will be lower when the car is running because the fluid is being circulated through the transmission. When you check the fluid level with the car running, you will get an inaccurate reading.

Why It’s Important

It is important to check the transmission fluid level regularly to ensure that your transmission is operating properly. If the fluid level is too low, the transmission may not be able to function properly and could eventually fail. If the fluid level is too high, the transmission could overheat and also fail.

How to Check the Transmission Fluid Level

To check the transmission fluid level, follow these steps:

1. Park your car on a level surface.
2. Turn off the engine.
3. Open the hood.
4. Locate the transmission fluid dipstick. It is usually located near the back of the engine.
5. Pull out the dipstick and wipe it clean with a rag.
6. Reinsert the dipstick into the transmission.
7. Pull out the dipstick again and check the fluid level.

The fluid level should be between the “full” and “add” marks on the dipstick. If the fluid level is low, add fluid to the transmission until the level reaches the “full” mark.

Conclusion

Always remember to turn off the engine before checking the transmission fluid level. Checking the fluid level with the car running can lead to an inaccurate reading and could result in transmission damage.
