Does Car Need to Be On to Check Transmission Fluid?

Introduction

Checking your transmission fluid is an important part of maintaining your car. It helps to ensure that your transmission is functioning properly and that you are not at risk of a breakdown. But do you need to have your car on to check the transmission fluid? The answer is yes, in most cases.

Why Do You Need to Check Transmission Fluid When the Car Is On?

There are a few reasons why you need to check your transmission fluid when the car is on.

1. To Get an Accurate Reading: When the car is off, the transmission fluid is not circulating. This means that you will not get an accurate reading of the fluid level or condition.
2. To Check for Leaks: If you check your transmission fluid when the car is off, you will not be able to see if there are any leaks. Leaks can cause your transmission to lose fluid and become damaged.
3. To Check for Contamination: If you check your transmission fluid when the car is on, you can see if there is any contamination. Contamination can come from a variety of sources, including coolant, water, and debris. Contamination can damage your transmission.

How to Check Transmission Fluid When the Car Is On

Checking your transmission fluid when the car is on is a simple process.

1. Park the car on a level surface: This will ensure that you get an accurate reading of the fluid level.
2. Put the car in park: This will prevent the transmission from engaging and moving the car.
3. Open the hood: Locate the transmission dipstick. It is usually located near the back of the engine.
4. Pull out the dipstick: Wipe the dipstick clean with a rag.
5. Reinsert the dipstick: Push the dipstick all the way back into the transmission.
6. Pull out the dipstick again: Check the fluid level on the dipstick. The fluid should be between the “full” and “add” marks.
7. Check the fluid color: The fluid should be red or pink. If the fluid is brown or black, it may be time to change it.

What to Do If Your Transmission Fluid Is Low or Contaminated

If you check your transmission fluid and it is low or contaminated, you will need to take action.

• If the fluid is low, add more fluid: You can purchase transmission fluid at most auto parts stores.
• If the fluid is contaminated, you will need to change it: You can change the transmission fluid yourself or you can take your car to a mechanic.

Conclusion

Checking your transmission fluid is an important part of maintaining your car. It is a simple process that can help you avoid costly repairs.
