My Check Engine Light Is On-Is It My Transmission?

My Check Engine Light Is On-Is It My Transmission?


Some Check Engine Problems Can Seem Like Transmission Problems,


You’re driving down the road, when all of a sudden a light on the dash starts flashing. And now the car barely accelerates; the transmission seems to be starting in high gear and it won’t shift. Oh, no! You’re going to need a new transmission!


 If My Check Engine Light Is On, Will I Need A New Transmission?


No, probably not. Those conditions usually indicate a computer system problem, not a transmission failure.


The fact is, nearly every system in today’s cars is controlled by computer, and most of those computers are networked together, sharing information as you drive. That level of control makes for really efficient operation and performance.


But it also creates a problem: That integration between the control systems means that a problem in one system can affect every other system around the car.


What does that mean to you? It means that your “transmission” problem could actually be caused by a faulty brake light switch, a loose wire on an engine load sensor, a faulty vehicle speed sensor, or dozens of other sensors or switches that might not seem to have anything to do with the transmission at first glance.


 Will You See If The Check Engine Light Has To Do With The Transmission?


How do you know whether you’re dealing with a transmission problem or a problem in one of the many related systems? You can’t. Without special equipment, education, and experience, no one can.

Q) Why is my check engine light on?


A) The check engine light, service engine soon light, overdrive light flashing, and on some Honda’s The D4 or D5 light flashing. These are various ways that automobile manufacturers have enabled their vehicles to signal that one of its computer systems has detected a fault. If you see any of these lights come on. You should have a competent repair facility scan the system for trouble codes. At Transmission Clinics we offer this service free of charge. Give us a call and we’ll get you in.

In many cases, you may have a minor problem that needs your attention. Don’t wait until it becomes serious.



Q) How long does an external diagnostic take?


A) The time it takes to do an external diagnostic varies. Depending on the make and model of car. Also depending on the customer concern. At Transmission clinics we generally ask that you set aside anywhere from 2 to 4 hours to allow us to complete an external diagnostic procedure.



Q) What does an external diagnostic accomplish?


A) The goal of the external diagnostic procedure is to determine whether or not the transmission has a serious internal problem or some other less serious external problem. The same applies to manual transmissions and manual clutch systems.

The priority here is to properly diagnose the customer concern/drivability issue.



Q) Should I get a transmission flush?


A) Although regular transmission maintenance is important. Transmission Clinics does not recommend transmission flushes. Automatic transmissions have an internal filter. This filter over time collects debris. If the fluid is changed without changing the transmission filter, which is what happens with a transmission flush.

This debris is left inside the transmission, and will immediately contaminate the new transmission fluid. If you think it’s time for a transmission fluid and filter change, give us a call and we can discuss it.
