A faulty transmission control module can be a really tough problem. Imagine yourself driving down the highway, and all of a sudden your car couldn't shift into a higher gear. That's pretty dangerous, right? You have to stall on the side for a moment, or endure a sluggish roll home. Read this guide to know the dos and don'ts when finding a replacement before the problem gets worse.
- Find a transmission control module that's compatible to your vehicle. Aftermarket manufacturers of TCMs specify the car make that works well with their devices, so you have to check that one.
- Select a transmission control module that's already configured and ready to use because tuning can be difficult and time-consuming. However, if you like to input your specific parameters like RPM and speed, then a module that's programmable and user-friendly is the best one for you. Some devices even have data logging and fault diagnosis. These data are very handy especially if you need to repair your car.
- If you want to upgrade to a better module, make sure that the cables on your vehicle are fit with the TCM. Otherwise, you may have to purchase cables that are sold separately.
- Choose a TCM that has shock resistant and waterproof housing. It helps to maintain your module in good condition for a long period of time.
- Look for a TCM that comes with warranty. Remember that it contains electronic parts, and it can wear out easily if not maintained properly.
- DO NOT rebuild an already worn-out or broken TCM if you have no experience with the electronic parts. You will only risk the other parts connected to it, and endanger yourself.
- DO NOT purchase a transmission control module from a brand that you don't know. It's better to check their website first, or ask from people who might know any information.
