Is it my Transmission Control Module or My ECM?
This is a Transmission control module

Transmission problems can be caused by a number of things. One of those things can be a vehicle’s Engine Control Module (ECM) . It’s important to understand though that if you are having troubles with your transmission, it’s not recommended that you blame it on your vehicle’s computer right away. You should always try to perform an ECM reset first before ruling out its a bad ECM.

Like with most vehicle problems, you need to start with the most simple issues that could cause your transmission to act up. A simple check to make sure your transmission fluid levels are okay could save you a lot of headaches.

Other problems that can cause your transmission to act up can usually be identified with a few diagnostic tests. If you have a problem like low pressure in your transmission case or a bad transmission oil pressure sensor switch, this could tell your engine’s computer to turn on the check engine light.

More testing!

Diagnostic tests may also turn up a sticky valve problem, bad transmission speed sensor or a bad transmission control solenoid. These are all problems that may have nothing to do with your ECM. That’s why it’s important to check other problems before you go changing your vehicle’s computer.

To find out if you have any of the above transmission problems or any other transmission problems, you might want to consult your dealership or a transmission specialist. The tests alone can be pretty easy to perform, but finding out exactly what the test is telling you may take a professional to help.

You may also want to take into account that if the diagnostic test offers you up a bigger problem then just your vehicle’s ECM not working correctly, you may end up at a dealership or transmission shop anyway, so why not go to one to begin with? Let’s face it, how many DIYers really have the equipment like a hoist in their garage to do major transmission work?

Whatever the case may be, if you feel like your transmission is acting up, be it an ECM problem or one of the many other transmission problems that can come about, waiting for a rainy day to get them fixed is not a good idea. Problems like these won’t go away and will only compound themselves in time. Eventually, you will end up stranded somewhere with a vehicle that doesn’t run.
