Can Transmission Fluid Cause Check Engine Light?

Transmission fluid can sometimes result in the opening of the check engine light. The transmission fluid is essential for lubricating the system’s components.

Extreme friction may happen in the absence of adequate lubrication, which may cause damage to the transmission’s components. Consequently, the check engine light can come on. If necessary, check the fluid levels and add some.

Similarly, overfilled transmission fuel can cause foaming, resulting in system damage in one way or another. It can lead to overheating or hard shifting, leading to switching the check engine light.

Contaminated or old transmission fuel can cause a loss of hydraulic power, leading to a lack of pressure needed for transmission to stay in gear.  

What Does Low Or Bad Transmission Fluid Cause?

Your automobile won’t produce as much hydraulic pressure when your transmission fluid is low, which can cause gear slippage. A common symptom of gear slippage is improper acceleration. If your transmission fluid level is low, your car may run at high RPMs while traveling slowly.

Once contaminated, your fluid’s cooling capacity will be reduced, leading to an overheated transmission. Once your transmission overheats, it might impact your car’s other components, like its engine’s cooling system. A transmission that is too hot might harm your vehicle permanently and irreversibly.

What Are The Signs And Solutions To The Transmission Fluid Problems?

Transmission Fluid

One can detect transmission fluid problems through various indicators, and the issues are as follows:

  • Your vehicle may have a burning smell.
  • Fluid may leak from the gaps between the different car parts.
  • Slippage of gears could be a real indicator of something wrong with your vehicle.
  • Unnecessary movements while driving. 
  • Always keep a check on engine lights.

Solutions To Transmission Fluid Problems

If you observe your car facing any of the issues mentioned above, unhesitantly go to a mechanic and get your vehicle checked.

Transmission fluid issues can also be treated with the right products at home. Still, most of them need professional assistance as our life depends on our vehicles, and it is extremely dangerous to drive unsafe cars. 

Can A Transmission Fluid Change Cause A Check Engine Light?

The sensors on your car are there for a reason. Therefore, you shouldn’t ignore them when your check engine light flashes; transmission is one of several potential causes.

Even while it might not appear that anything is wrong, those sensors can identify problems long before you even feel them. It is safe to say that transmission fluid change causes a check engine light, which should not be ignored if you want a healthy life for yourself and your vehicle.

Can A Transmission Leak Cause The Check Engine Light To Come On?

Yes, if there is an issue with the transmission fluid or if it’s leaking, the check engine light will notify us.

Leaking fluid has many negative effects on the vehicle, such as breakdown, pan gasket damage, axle leaks, and many more! All of these transmission damages can cause the check engine light to come.

How Often Should You Check The Transmission Fluid?

It is recommended to check one’s transmission fluid after 15-30 days. Checking in daily intervals can help the owner to keep everything in check. It is very easy to check for transmission fluid issues as one can effortlessly do it at a gas station once you are done with the gas fill.

When Should You Change The Transmission Fluid?

It depends from car to car; some manual says to change it after 30 months, some say more or less. But do keep this in mind: check all the signs of transmission fluid damage to avoid any last-minute hazards.


Will a warning light come on if the transmission fluid is low?

A warning light on the dashboard will turn on when the transmission fluid level drops. The warning light shows that the fluid is heating up more than usual, and the fluid has to be examined.

What is the most common reason for the ‘check engine light?

The onboard diagnostic system uses the “check engine” light to alert you of problems. However, that something might be any number of other things, great or tiny. It might turn on due to a minor issue, such as a gas cap that is loose or broken. It might also indicate a serious engine breakdown. One of the most common reasons could be an oxygen sensor malfunction. 

Can ‘check engine light mean transmission problems?

Your check engine light may turn on as a result of transmission issues. The engine control module (ECM), the primary computer in your car, communicates with system sensors to ensure everything is operating as it should.

The ECM will activate the check engine light if the transmission sensors signal a malfunction. Thank you for reading:)


Check engine lights can also be caused by transmission fluid problems. The components of the transmission may be damaged if there is an imbalanced amount of transmission fluid. Furthermore, speed and overall performance may also be adversely affected. If it is not too late, replacing the transmission fluid is the best course of action.
