Here are the steps on how to add transmission fluid. This guide will walk you through adding fluid, checking for leaks, and more.

Your vehicle’s transmission system is a complex network of parts that work together to provide smooth and precise gear changes as you drive. One of the most vital components of transmission is the fluid.

Transmission fluid helps to keep all of the components in the transmission cool and lubricated, making it a key player in keeping your car running smoothly. 

Over time, transmission fluid can break down and become contaminated, leading to shifting problems and transmission failure. Adding fresh transmission fluid is an easy way to keep your transmission in good working order.

If you need to add transmission fluid, don’t worry! It’s a quick and easy process that most people can do themselves. Just follow the steps below, and you’ll be adding fluid to your transmission in no time.

How To Check Transmission Fluid

How To Check Transmission Fluid

By simply following these steps, you will be able to check the transmission fluid level in your car.

What You’ll Need:

  • A funnel (if levels are low)
  • Fresh transmission fluid (check your owner’s manual to find out what type of fluid your car uses)
  • A clean, lint-free cloth
  • latex gloves (optional)

Steps to Follow

1. Locate the Dipstick

The first thing you need to do is find the dipstick. In most cases, it will be located near the back of the engine on the driver’s side. However, on some models, it may be located on the passenger side.

It should look like a long thin rod with a handle on the end. If you’re unsure where to find it, consult your owner’s manual or look for a label under the hood that says “transmission fluid.”

2. Check the Level 

Once you’ve found it, pull it out and wipe it off with a clean, lint-free cloth and reinsert it. Then, remove it again and check the level. The fluid should be at or near the “full” line on the dipstick. If it’s not, then you’ll need to add more. If the vehicle isn’t parked on level ground, the reading may not be accurate, so keep that in mind.

3. Fluid Condition

When you check the fluid level, take a look at the color and condition of the fluid as well. Transmission fluid is typically red, pink, or brown, and it should be clear or have just a slight tint to it. If it’s murky or smells burnt, then it needs to be changed. Another way to check the condition of the fluid is to see if it’s foamy or has a gritty texture. If so, then it’s time for a change.

What is Low Fluid?

If the level of your transmission fluid is low, it can cause shifting problems and eventually lead to transmission failure. The most common cause of low fluid is simply leaking in the system. A small leak can result in a big drop in fluid level over time, so it’s important to check for leaks and have them fixed as soon as possible.

Another common cause of low fluid is “transmission fluid cooler line leaks.” This happens when the lines that carry transmission fluid to and from the cooler (a device used to keep the fluid cool) develop small cracks or holes and begin to leak.

To add transmission fluid, you will need a funnel and some fresh fluid. The type of fluid you’ll need depends on your vehicle, so be sure to check your owner’s manual or look for a label under the hood that specifies what type to use. You can usually find this information on the dipstick as well.

1. Place the funnel in the transmission check tube

Once you’ve made sure the vehicle is parked on level ground, locate the transmission check tube. The check tube is a small opening that allows you to check and add fluid to the transmission without having to remove any panels or covers. The exact location will vary depending on the make and model of your vehicle, but it’s usually located near the back of the engine on the driver’s side.

2. Add the fluid in small amounts

Slowly pour fresh fluid into the check tube until the level reaches the “full” line on the dipstick. If you don’t have a funnel handy, you can use a clean plastic bottle with a small opening (like a water bottle) to add the fluid. Just be careful not to spill any!

3. Recheck the level with the dipstick after each pour

Once you’ve added fluid, reinsert the dipstick and pull it out again to check the level. Make sure it’s at or near the “full” line. If not, add a little more until it reaches that point. Remember to clean the dipstick off with a clean cloth each time you check the level.

Frequently Asked Questions 

What happens if you drive on low transmission fluid?

If the level of your transmission fluid is low, it can cause shifting problems and eventually lead to transmission failure. The most common cause of low fluid is simply leaking in the system.

A small leak can result in a big drop in fluid level over time, so it’s important to check for leaks and have them fixed as soon as possible. Common symptoms of low fluid levels are hard shifting, slipping gears, and delayed engagement.

How long should I let my car run after adding transmission fluid?

You should let your car run for a few minutes after adding transmission fluid so that the new fluid can circulate through the system. However, you don’t need to let it run for more than a minute or two in most cases.

What happens if you overfill transmission fluid?

If you overfill your transmission fluid, it can cause damage to the seals and gaskets. This can lead to leaks and other problems. It’s important to only add enough fluid to reach the “full” line on the dipstick. Often, it’s best to err on the side of adding less rather than more.

How often should you change your transmission fluid?

The frequency with which you should change your transmission fluid depends on the make and model of your vehicle, as well as your driving habits. In general, though, most experts recommend changing it every 30,000 miles or so. You can check your owner’s manual for specific recommendations.

How long can a car run without transmission fluid?

A car can run for a short time without transmission fluid, which will eventually cause the transmission to overheat and fail. It’s important to keep an eye on the level of your transmission fluid and add more if it starts to get low.

Factors such as driving habits, climate, and vehicle type will affect how long a car can run without transmission fluid. In general, though, most experts agree that it’s best to err on the side of caution and add more fluid sooner rather than later.

Conclusion

Adding transmission fluid is a pretty simple task that anyone can do. Just be sure to check your owner’s manual or look for a label under the hood to find out what type of fluid to use, and be careful not to overfill it.

If you feel like you don’t have enough knowledge to do it yourself, take it to a mechanic, and they can do it for you. Thanks for reading!
