Do You Check the Transmission with the Car Running?

The transmission is a vital part of your car, and it’s important to keep it in good working order. One of the best ways to do this is to check the transmission fluid regularly. But should you check the transmission with the car running?

Checking the Transmission Fluid with the Car Running

There are two schools of thought on this issue. Some mechanics believe that you should check the transmission fluid with the car running, while others believe that you should check it with the car off.

Those who believe that you should check the transmission fluid with the car running argue that this is the best way to get an accurate reading. When the car is running, the transmission is circulating fluid, and this will give you a better idea of the fluid’s condition.

Those who believe that you should check the transmission fluid with the car off argue that this is a safer option. When the car is running, the transmission fluid is hot, and you could burn yourself if you’re not careful. Additionally, if you’re not familiar with how to check the transmission fluid, you could damage the transmission if you do it wrong.

Which Method Is Right for You?

Ultimately, the decision of whether to check the transmission fluid with the car running or off is up to you. If you’re confident in your ability to do it safely, then checking the fluid with the car running may be the best option. However, if you’re not comfortable doing this, then it’s better to err on the side of caution and check the fluid with the car off.

Here are some additional tips for checking the transmission fluid:

• Park the car on a level surface.
• Put the car in park.
• Open the hood and locate the transmission dipstick.
• Pull out the dipstick and wipe it clean.
• Reinsert the dipstick into the transmission and pull it out again.
• Check the fluid level on the dipstick. The fluid should be between the “full” and “low” marks.
• If the fluid is low, add more fluid until it reaches the “full” mark.
• Reinsert the dipstick and tighten it.

Checking the Transmission Fluid Regularly

It’s important to check the transmission fluid regularly, regardless of whether you check it with the car running or off. The frequency with which you should check the fluid will vary depending on your car’s make and model. Consult your owner’s manual for specific recommendations.

By checking the transmission fluid regularly, you can help keep your transmission in good working order and avoid costly repairs down the road.
