The transmission control module (TCM) is a fundamental part of the automobile since it is in charge of regulating gear changes in a computerized way.
Thus, it is not only a mechanical part but also fulfills a technological function by communicating with other important parts of the vehicle and carrying information to improve, for example, the efficiency in the transition of changes, fuel economy, and power when accelerating.
Thus, a properly functioning TCM will be enabling the regulated and optimal driving of your vehicle.
That said, it will be important to know some warnings and alerts about the Ford transmission control so that you can act in time in the event of a problem. And it will always be convenient to have knowledge about your vehicle and its operation, as it can get you out of trouble at times when a fault needs to be fixed immediately, with the need to reset the system and the computer completely.
But then, the question is: can the Ford transmission control module be reset? The answer is yes, and it can be done manually. Here’s everything you need to know. Read on.
How To Reset Transmission Control Module Ford
A problem or defect in the transmission module can be common in some cases -even more so in models such as the Ford Focus, Ford Fusion Assembly, and Ford Fiesta (which have already been recalled)-, so learning how to fix it can be very helpful.
Likewise, a professional mechanic can give you a solution, although the labor is not cheap since the work is time-consuming. At the same time, if you need to change an imported part, the cost will increase.
For these reasons today we bring you a guide so you can reset the Ford transmission control yourself. With this technique, you will be able to reset the computer operation manually. Let’s get to it:
Start your vehicle. As a first step, you should take the key and start your car (without starting the engine). Then turn the key to position 2, or secondary operating position/gear.
Once you have done the previous step, you will see how your dashboard lights up. Next, press the accelerator and keep the car in constant gear. Wait 10 to 15 seconds.
Wait a few minutes and put the vehicle in parking mode or lock position (P), in order to prevent it from moving. To do this, turn off your car by applying the service brake and placing the lever in position P.
Now just wait a few minutes and start the vehicle again. Remember not to start the engine, only the ignition. Again wait about 20 seconds to turn the car off again.
Now comes the final step to getting the module reset. Turn the key and turn off the vehicle one last time. Turn your car back on and switch it to S mode – this will help you to reach a higher speed and you will be able to hear the sound of the engine perfectly.
Check that everything works perfectly and, if you followed all the steps mentioned above, you will see that your Ford transmission control module has been reset correctly. The car will be able to notify you of the reset indicating that the transmission is complete.
You can now start your car and start driving at different speeds until the entire system is gradually reset. After setting different speeds and turning off your vehicle, your Ford’s transmission will enter the relearning stage.
The good news is that you will only need a few seconds for this to happen, without requiring another extra step to reset the module, as the computer will stay reset and working.
How To Detect If The Ford Transmission Control Module Is Malfunctioning?
What happens when the transmission module fails and is there a way to detect it? When there are problems in the TCM the signals that the computer processes, and that come from the engine, will not be performed correctly. In addition, it is possible that signs of speed control, shift and gear failures, transmission overheating or acceleration problems may appear.
Observing a decrease in fuel, difficulty shifting at high speeds or a light on your dashboard may also be a sign that something is wrong with the transmission control. If you notice any of these issues with your vehicle it is likely that the module has been damaged and requires immediate intervention.
Also, be aware of the following warning signs:
- You notice inconvenience when shifting to higher speeds.
- You notice very little acceleration when you start the car.
- Your car gets stuck in different gears.
- You have trouble slowing down.
- You have difficulty shifting or have trouble moving the shifter.
- Your computer indicates some alerts or shows something out of the ordinary.
- When you start your car, accelerate or leave the car in gear, you hear a strange noise.
- You smell burning oil as if something was overheated.
- Your car shuts off when you put it in reverse or won’t let you put it in reverse.
- You have problems starting it because it does not move forward.
Finally, to reset the Ford transmission control module you will only need 30 minutes, although if you prefer to go slowly and step by step to avoid any inconvenience, it may take you more time.
Likewise, if you have doubts or think you may make a mistake when you want to reset the module, it is always best to go to a mechanic who will evaluate the car and give you the correct diagnosis of what is happening.
Be sure to repair the problem as soon as possible, since it is risky to drive a car with a damaged transmission. In addition, try to perform annual tests to check the general condition of your car, avoiding future problems in the gear control module and other important parts.
