Turning Key Position

The first thing is to go through the key position. This is the first thing when resetting the transmission control model. Turn the key position until it settles to 2. Inspect the dash lights of your vehicle and make sure that they’re visible. If they’re visible, then you can proceed to the next step.

Note that in this first step, you don’t need to push the accelerator or start the vehicle. Be careful after settling the key position. That having been said, keep your ears open and listen to sounds. There should be two clicks and after that, the dash lights will be turned on. Even at this point, be sure not to turn the engine on.

Pressing the Gas Pedal

Once you’re done with the key position and the dash lights, you can move to the next step. This one is all about the gas pedal.

Now make your move and press the gas pedal. Check that you’re pressing it down. It’s also likely to help if you push the accelerator pedal to the floor as this will help activate the kick-down switch.

Note that activating the kick-down switch is all you need at this point. Don’t detach the force from the gas pedal. Keep on pushing downwards. Read on for the next step.

Well, if you want to reset the transmission control module for your Chevy, you’ll need to be a little patient. Don’t just expect quick transmissions.

Nevertheless, this point should cost you just 10 minutes. And as we’ve stated, don’t remove the force from the gas pedal.

Note that the point here is to wait. Within this time frame, 10-12 seconds should be enough for the gas pedal to start working towards resetting the process. Just push and wait.

Turning the Key Off

Once you’re done pushing the gas or rather the accelerator pedal for around 10-12 seconds, you will have to go ahead and move the key again. Be sure not to release the pedal. In fact, you will have to do this entire process keeping your feet on the pedal. Hope you remember you had earlier turned the keys to 2, now you will have to go through them again and set them back to their previous position.

You will just need to turn the key off (to zero), which can be done with your hands. We understand that you might have a tendency of turning the key to zero and removing it.

 But in this case, do not remove it (though this method of not removing the key is not always implemented in every model. Therefore, you should check your model and determine if the key should be removed or not. Otherwise, in most cases dealing with Chevy models, the key is not removed.

Releasing Gas Pedal

After turning the key back to zero, you can stop pushing the gas/accelerator pedal. Some people tend to get careless and release the pedal even before turning the key off/to zero. But trust us, you don’t want to repeat the same mistake.

Thus be sure to keep your feet on the gas pedal throughout the previous step, and only stop pressing it when you’re satisfied the key is turned back to zero.

Well, some of us don’t do too well when it comes to waiting. But doing it will help make the whole reset process easier. After taking your feet off the gas pedal, give your Chevy some rest. 

The engine needs to reset for around 2-3 minutes. At this point, check that you’ve kept the key left in the ignition (in the OFF position). Still, do not remove the key, take some time and then proceed to the next part.


Now you’re almost practically done with the process. You’re already dealt with the Engine Control Unit process as well as the Transmission Control Unit Process. The only thing remaining is to drive. The stated ECU and TCU process will work cooperatively to adapt your driving technique. They will definitely monitor the new driving pattern and cope with that.

After finishing the TCU and ECU programming, you will need to subject your vehicle to a drive. The drive should last anywhere between 15 and 20 minutes. You realize that you’re actually teaching the engine how to drive. So, no need to go for a race. But if that’s not the case, be sure to go for a decent speed. The speed at which you usually drive your car should be the same in this case.

The other thing is to make sure the transmission you are considering is normal and smooth. This way you will be able to shift your transmission and experience something new in your Chevy model.
