Step by Step Resetting Transmission Control Module

1: Turning Key Position

The first step of resetting the transmission control module is to go through the key position. You have to turn the key position and settle it to 2.

Check the dash lights of your car. Make sure that the dash lights are visible. When they are visible, you are ready for the next step.

But in the first step, you don’t need to push the accelerator and start the car. Please don’t do it in the beginning. After setting the key position, be careful.

Keep your ears open. You will listen to sounds. There will be two clicks. And after that, the dash lights will get turned on. Even in this position, do not turn the engine on.

2: Pressing the Gas Pedal

Now that you are done with the key position and the dash lights, you have to move to the next step. Here, you will go through the gas pedal.

Make your move and press the gas pedal. Make sure you are pressing it down. It would help if you pushed the accelerator pedal to the floor because it will help activate the kick-down switch.

In this position, activating the kick-down switch is all you need. Don’t remove the force from the gas pedal. Keep pushing it downwards.

3: Keep Waiting

Now, if you are here to reset the transmission control module for your Chevy, you have to be a little patient. You cannot expect faster changes.

However, you only need 10 minutes in this step. We have said before, don’t remove force from the gas pedal.

In this step, all you need to do is wait. 10-12 seconds will be enough for the gas pedal to start working for the resetting process. Push it and wait!

4: Turning the Key Off

After you are done pushing the accelerator pedal for about 10-12 seconds, you have to go ahead and move to the key again. But don’t release the pedal.

Remember that you have to do this whole step keeping your feet on the pedal. Do you remember you had turned the keys to 2 before? Yes, and now, you have to go through them again and put them back to their previous position.

All you need to do is turn them the key off. With your hands, turn the key to zero. You might have a habit of turning the key to zero and removing the key.

But in this case, you cannot do the same thing. You cannot remove the key. After turning the key back to its previous situation, you have to keep the key there.

Please do not remove it. However, this method of not removing the key doesn’t go with every model.

So, check your model and know if it is required to remove the key or not. Nevertheless, in most of the Chevy models, the key is not removed.

5: Releasing Gas Pedal

When you have already turned the key back to zero, you can remove the force from the gas pedal.

Some people often get careless and remove the pedal even before turning the key off. But we don’t want you to repeat the same mistake!

So, make sure you have kept your feet on the pedal throughout the previous step. And only remove the force from the gas pedal when you are done turning the key back to zero.

6: Wait Again

We understand you don’t want to wait. But doing it will help you in making the reset process easier. After you remove your feet from the gas pedal, you have to give your Chevy some rest.

Your engine needs to rest for about 2-2.5 minutes. Ensure that you have kept the key to the left in the ignition where the OFF position is. Don’t move the key. Take some time and then move into the next part.

7: Ready, Steady, Go

So, you are almost done with the process. You have already done the Engine Control Unit process along with the Transmission Control Unit process.

All you have to do now is drive! The TCU process, along with the ECU, will work cooperatively. They will try to learn your driving method. They will monitor the driving pattern you have and cope with that.

When you’re done with the TCu and ECU programming, you have to take your car to a drive. The drive can be 15 minutes to 20 minutes.

You have to remember that you are teaching your engine how you drive. So, do not try to go for a race. You don’t race your car every time, do you?

If not, then make sure you go for decent speed. The speed you usually run your car will be the speed in this case too.

Make sure that the transmission you are selecting is normal and smooth. In this way, you can easily shift your transmission and have something new in your car!
