Your car's transmission fluid is essential to ensure smooth and reliable gear shifts.
Without it, your transmission could overheat or suffer from excessive wear and tear, leading to expensive repairs.
Regularly checking your transmission fluid is an essential part of vehicle maintenance, but did you know that it's best to check it when the engine is running?
In this article, we'll explore why checking your transmission fluid with the engine running is so important.
What is Transmission Fluid?
Transmission fluid is a specialized lubricant that helps your vehicle's transmission system run smoothly.
It provides a layer of protection between the transmission's moving parts, reducing friction and heat.
Transmission fluid also helps to transfer power from the engine to the wheels, allowing your vehicle to move forward.
Why Check Transmission Fluid with the Engine Running?
It's important to check your transmission fluid when the engine is running because this provides the most accurate reading.
When the engine is running, the transmission fluid is circulating throughout the transmission system.
If you check the transmission fluid level with the engine off, you may get an inaccurate reading.
This is because the fluid may have settled in the bottom of the transmission pan, making it appear as though there is too little fluid.
In reality, there may be enough fluid in the transmission, but it's not being circulated, so it's not visible on the dipstick.
Checking the transmission fluid with the engine running also allows you to check the fluid level and color at the same time.
If the fluid is low, it may indicate a leak in the system, which could cause damage to the transmission over time.
Additionally, if the fluid is discolored or has a burnt smell, it could be a sign of a more significant transmission issue, such as overheating or clutch wear.
How to Check Your Transmission Fluid?
Checking your transmission fluid is a straightforward process that you can do yourself.
Here's a step-by-step guide on how to check your transmission fluid with the engine running:
- Start your car's engine and let it idle for a few minutes to allow the transmission fluid to warm up.
- Locate the transmission dipstick, which is typically labeled and located near the transmission.
- Take out the dipstick and then wipe it clean with a cloth or paper towel.
- Insert the dipstick back into the transmission and pull it out again.
- Check the transmission fluid level and color. The transmission fluid should be between the two lines on the dipstick and have a clear, reddish color.
- If the transmission fluid level is low, add more transmission fluid to bring it up to the proper level.
- Also, if the transmission fluid becomes discolored or starts to smell burnt, it may also be time for a transmission fluid change.
What happens If Transmission Fluid is Low?
If the transmission fluid level is low, it can cause several issues with the transmission system.
These include:
- Overheating
- Slipping
- Wear and Tear
Overheating
Low fluid levels can cause the transmission to overheat, which can lead to damage to the internal components.
Slipping
Insufficient fluid levels can cause the transmission to slip or hesitate when shifting gears, which can cause erratic or delayed shifting.
Wear and Tear
Low fluid levels can cause increased friction and wear on the transmission components, which can lead to premature failure.
What happens If Transmission Fluid is High?
If the transmission fluid level is high then it can also cause several issues.
These include:
- Foaming
- Leaks
- Fluid Contamination
Foaming
Overfilled transmission fluid can cause foaming, which can lead to air bubbles forming in the fluid.
These bubbles can cause damage to the transmission components.
Leaks
If the fluid level is too high, it can cause leaks in the transmission system.
Fluid Contamination
Overfilling the transmission with fluid can cause the fluid to become contaminated with air, which can reduce the fluid's ability to lubricate the transmission components.
Therefore, it's essential to maintain the transmission fluid level within the recommended range to ensure proper operation and avoid transmission damage or failure.
Can Transmission Fluid be low Without a Leak?
Transmission fluid levels can decrease over time, even without a noticeable leak.
There are several reasons why the fluid level can decrease:
- Evaporation
- Normal Wear and Tear
- Transmission System Malfunction
Evaporation
Transmission fluid can evaporate over time, especially if the vehicle is driven in hot conditions.
Normal Wear and Tear
Over time, some transmission fluid will be used up by the transmission system to lubricate and cool the internal components.
This can cause the fluid level to gradually decrease.
Transmission System Malfunction
If there is a problem with the transmission system, such as a malfunctioning solenoid or a slipping transmission, it can cause the fluid to be used up more quickly.
It's essential to regularly check the transmission fluid level and maintain it within the recommended range to avoid damage to the transmission system.
If you notice that the fluid level is consistently low, it's important to have your vehicle inspected by a qualified mechanic to determine the cause of the problem.
What Things to Consider While Checking Transmission Fluid?
When checking the transmission fluid in your vehicle, there are several things you should consider:
- Vehicle's Owner's Manual
- Level and Color
- Condition
- Contamination
- Type of Fluid
Vehicle's Owner's Manual
Refer to your vehicle's owner's manual for specific instructions and recommendations for checking and maintaining the transmission fluid.
Level and Color
Check the fluid level on the transmission fluid dipstick and observe the color of the fluid. The fluid level should be within the recommended range, and the color should be a clear reddish-pink color.
If the fluid is brown or black or has a burnt smell, it may indicate that the fluid is contaminated or has deteriorated.
Condition
Check the condition of the transmission fluid. The fluid should be free of debris, particles, and metal shavings.
If you notice any of these, it may indicate that there is internal damage to the transmission system.
Contamination
Check for signs of fluid contamination, such as a milky or foamy appearance, which can indicate the presence of water or other fluids in the transmission fluid.
Contamination can cause damage to the transmission system and should be addressed immediately.
Type of Fluid
Make sure to use the recommended type of transmission fluid for your specific vehicle, as using the wrong type of fluid can cause damage to the transmission system.
By considering these factors, you can ensure that your transmission fluid is in good condition and that your transmission system is operating correctly.
How often Should Transmission Fluid be Checked?
The frequency of checking the transmission fluid in your vehicle depends on several factors, including the make and model of your vehicle, the age of the vehicle, and the type of driving conditions you encounter.
As a general rule, it's recommended to check the transmission fluid level at least once a month and before any long trips.
However, you should refer to your vehicle's owner's manual for specific recommendations for your vehicle.
Additionally, it's essential to follow the manufacturer's recommended maintenance schedule for your vehicle, which will typically include regular transmission fluid changes.
This schedule may vary depending on the make and model of your vehicle, but typically, it is recommended to change the transmission fluid every 30,000 to 60,000 miles or every 2 to 4 years.
Regularly checking and maintaining the transmission fluid in your vehicle can help to ensure that the transmission system operates smoothly and efficiently, providing you with smooth gear shifts and improved fuel economy.
If you notice any issues with your transmission system, such as slipping or delayed shifting, it's essential to have your vehicle inspected by a qualified mechanic.
Final Thought
In conclusion, checking your transmission fluid when the engine is running is essential for maintaining the health and longevity of your vehicle's transmission system.
By following the steps outlined above, you can ensure that your transmission fluid is at the correct level and in good condition, helping you avoid costly repairs down the road.
