5 Transmission-Related Problems That Can Trigger The Check Engine Light
When the check engine light comes on, it could be the result of a transmission issue. In some cases, the problem is easily resolved and does not require repair. If your light is on, here are some possibilities for what it could mean to your transmission.
Low Transmission Fluid
Your transmission fluid plays an important role in keeping the parts of the system lubricated. If the parts of the transmission are not properly lubricated, extreme friction can occur, which could result in damage. As a result, the check engine light can be triggered. Check the fluid levels and add some, if needed.
Solenoid Malfunction
The solenoid of your transmission is responsible for regulating how transmission fluid is dispersed throughout the transmission. Even with the proper level of fluid in your car, it can still experience a lot of friction because all of the components are not getting the amount of fluid that is needed. Your mechanic can determine if the solenoid is the culprit.
Cooler Lines Clogged
The transmission's cooler lines are responsible for helping to deliver fluids to keep the system cool. As you drive your car, the parts of the transmission start to heat up. If the parts are not being cooled, friction can occur and the transmission can start to overheat. When the transmission overheats, it can start to slip, causing the check engine light to engage. To resolve this issue, the cooler lines need to be unclogged and the filter should also be changed. There is also the possibility that the pump to the cooling lines is not functioning, which requires professional attention.
Transmission Control Module Failure
The transmission control module is responsible for controlling different aspects of your system, including when and how to shift gears. When it is not working properly, the check engine light comes on and you could have problems with shifting or your car might not start in the "park" gear. The only solution to this is to have your control module replaced.
Sensor Failure
The check engine light relies on a range of sensors to report the conditions of different components of your car. If a sensor is malfunctioning, it can trigger the check engine light even if there is nothing wrong. Replacing or tweaking the sensor might be necessary to resolve the light issue.
Even if you are not experiencing problems, it is important to have the check engine light checked out when it is engaged. You can also contact a local repair shop that specializes in transmission repair, such as American Transmission Center, if your transmission is to blame.
