How to check transmission fluid without dipstick

How to check transmission fluid without dipstick: The dipstick helps show the oil level, lets you know the amount of oil added, and detects abnormalities.

If you have a car with a transmission, you probably already know how to use a dipstick. But new cars do not have this tool. Many new users ask how to check transmission fluid without any dipstick.

So, let’s find out through the article below to answer!

Why should you check your transmission fluid level?

The reason to check the transmission fluid level is to make sure that the car is running smoothly. They are based on the fluid coordination of moving parts.


As with any vehicle component, checking the transmission fluid level is routine maintenance. As such, it is essential for your car.

If you examine the transmission fluid, you will discover the common problems that you encounter. One of the most common cases is the transmission fluid leak or damage. They are found for a long time of use and operation of the vehicle.


The cause of low transmission fluid levels is that the driveline is poorly lubricated and therefore works less efficiently.


Automated cars work on the hydraulic principle. They need oil pressure to function properly.


Also, the pump sucks air out of the transmission fluid if they are low. As such, the clutch components will fail unexpectedly.


However, a high level of transmission fluid is not a great sign. If it is at a high level, air bubbles will form.


At that point, the fluid needs to work to compress this air bubble, reducing the line pressure to a smaller level. It’s dangerous, leading to a fiery clutch.


As such, it is crucial to check the fluid level regularly. You need to review it every one or two months.

How to check transmission fluid without a dipstick?

As mentioned above, your modern car may not have a dipstick, so how do you check the fluid level?

Here are some suggestions for you when you want to maintain your car.

1. Please check if your car has dipstick or not

Some manufacturers have improved the dipstick by using level sensors. However, you can check the position of the dipstick if the manufacturer does not mention it. They can install them in different places of the car.

Dipsticks may be under a hood of your car. So you need to check this location first.

The dipstick feature has a T-shaped handle that will help you find it more accessible.

The next step is for you if you can’t find a rod or the design doesn’t include one.

2. Check your manual to see if your vehicle has a sealed transmission

All cars come with a manual, so take advantage of it. You need to read them to find out if your car is an automatic transmission with a dipstick or a sealed transmission.

If your car has a sealed transmission, you should take the vehicle to a repair center. Here, professional repairmen will help you.

3. Check Transmission Fluid Temperature

You should check the drain plugs and fill plugs. This test requires you to be under the cars and the temperature must be suitable.

So the fluid temperature is between 185 and 194 degrees with an idle time of 600 to 800 rpm.

It would help if you used a scan tool or even a regular kitchen thermometer to check the temperature of the liquid.

4. Supply a large amount of air to fill the plug

Specifically, the process to perform this step is as follows:

  • You need to clean up and not let the fenders get stuck with bolts. Also, there, find the plug and perform the disconnection.
  • Next you need to find the position of the fill hole along with the fill adapter mount. So it would be better if you connect this fill adapter to the vacuum regulator.
  • At the same time, the next thing to do is adjust the regulator and liquid draw tank and make sure the air is at 100psi.

5. Test the drain plug

You will need a wrench on the inspection plug and now you can loosen it.

You will also need to place some sort of drain pan under the inspection plug once the inspection plug has been loosened enough to be removed by hand.

Be sure to wear some type of work glove to avoid getting burned by the inspection plug in the fluid, once the inspection plug is removed.

If fluid begins to drain from the inspection plug opening, it is too full.

Wait until it stops draining then reinstall the inspection plug now that the fluid is at the proper level if the fluid draining was dark brown or black then it needs to be changed.

If no fluid comes out when the inspection plug is removed, remove the fill plug insert along that funnel in the fill plug opening and slowly add fluid once fluid begins to drain from the fill plug opening. inspection, stop adding fluid and reinstall the inspection plug and fill. plug.

Now the fluid is at the proper level if the fluid draining was dark brown or black then it needs to be changed.

Signs of low transmission fluid

1. Noise

If you hear an abnormal sound, it may indicate a low transmission fluid level. However, it is very difficult for you to discover them on your own.

At this point, you need a mechanic or technician to help you inspect it more closely in order to find this problem as soon as possible.

At the same time, each vehicle with a different engine model will have different noises. Your car is excellent if you don’t hear even the slightest noise.

2. It has a strange smell

The burning smell you smell may be because the fluid is at a high temperature in your car. Transmission fluid not only keeps many parts of the transmission properly lubricated, it also prevents the transmission from misfiring by providing necessary cooling measures.

The cause of this problem was the low fluid level. In other words, it’s a sign that the fluid is leaking or contaminated and needs to be changed. At that time, you should take the car to the nearest workshop or repair center.

If you let this go on for too long, the transmission will gradually erode and become damaged. More Dangerous makes it challenging to use the vehicle, even causing damage to the vehicle.

3. Transmission fluid leak

Transmission fluid leak is probably one of the easiest ways to determine that your transmission needs attention. Automatic transmission fluid is vital to your vehicle’s ability to shift gears, so even a small leak while driving can quickly become a major problem.

Automatic transmission oil is bright red, clear, and scented when everything is working properly.

When you test your automatic transmission oil, make sure it doesn’t have dark colors or a burning smell. If so, you will need to take the car to a mechanic to have it replaced.

Unlike gasoline engine, the transmission does not consume or burn oil during use, so if you notice your transmission oil running low, then it must have leaked somewhere.

If you suspect your transmission has an oil leak, locate it and fix it immediately.

4. Number Swipe

In a good working transmission, the car will either run in the gear you choose, or the computer will assign a rev range until you or the system start to shift.

However, a gearbox failure that causes the gears to slip can be caused by low fluid levels,

and the car may change gear abnormally while driving (with manual transmission) and push the gear stick to 0.

This is the worst and potentially the most dangerous. When you’re holding down the accelerator to keep the car from losing control, the last thing you want is a transmission that’s not sending power to the wheels.

Don’t wonder if this is a problem because if it is, take itTake the vehicle in for service and remind the mechanic to double check the transmission.

What are the most common causes of transmission failures?

The most common causes of transmission failure. By knowing the most common causes of transmission failure, you can take steps to prevent it from happening to your vehicle. The most common causes of transmission failure are worn gears, fluid leaks, and overheating.

Worn gears are the most common cause of transmission failure. When the gears wear out, they can no longer mesh properly with each other, causing the transmission to slip. This can cause a loss of power and eventually the transmission will fail completely.

Fluid leaks are another common cause of transmission failure. When transmission fluid leaks, it can cause gears to slip and eventually fail. Overheating is another common cause of transmission failure. When the transmission overheats, the fluid can break down and cause the gears to slip.

If you think your transmission might be failing, it’s important to have it checked out by a qualified mechanic as soon as possible. Transmission failure can be expensive to repair, so it’s best to catch it early before it does more damage.

How to Check Transmission Fluid Without a Dipstick

If your car does not have a dipstick, you can check the transmission fluid level by removing the fill plug. The fill plug is usually located on the side or bottom of the transmission. Once you have located the fill plug, use a ratchet and socket to remove it.


Once the fill plug is removed, you should see a stream of transmission fluid coming out. If the stream is steady and consistent, that means the fluid level is full. If the flow is intermittent or no fluid comes out, that means the fluid level is low and you will need to add more.

Transmission Fluid Addition

If your transmission fluid is low, you will need to add more. The best way to do this is by using a funnel to pour the fluid into the fill hole. Once you have added the desired amount of fluid, replace the fill plug and tighten it with a ratchet and socket.


It is important to regularly check the transmission fluid level to prevent transmission failure. If you notice your fluid level is low, add more as soon as possible.


By following these steps, you can easily check your transmission fluid level without a dipstick. Regular maintenance will help keep your transmission in good working order and prevent costly repairs in the future.

Checking Transmission Fluid Levels

If you’re going to check your transmission fluid level at home, it’s a good idea to warm up the car before doing so. If the car is checked while the engine is cold, it could give an inaccurate reading when you use the dipstick. After driving for about 10 minutes, park on a level surface and let it run.

Shift up and give the transmission a chance to spend a few seconds in each gear range. Then put the car back in park and set the parking brake.

Open the hood and locate the transmission dipstick. Your owner’s manual is a good place to look for instructions if you can’t find them. Typically on a rear wheel drive car, the dipstick will be closer to the passenger side, near the engine. Front wheel drive cars will have the dipstick on the driver’s side, closer to the transmission.

Pull out the dipstick, wipe it with a clean rag or paper towel, and then reattach it to the transmission filler tube. Pull the dipstick out of the tube and check the fluid level against the marks near the end of the dipstick. Liquid can be added if necessary.

Every vehicle is different, something you’ll want to keep in mind. Recently some manufacturers have decided to remove the dipstick and replace it with a sealed unit, which requires electronic testing or a computer scan. If you don’t want to check your transmission fluid levels at home or if your car has one of these sealed units, our service team will be happy to do it for you.
