How to Reset Transmission Control Module Chevy Silverado 1500/2500 in 06 Steps
You would usually need to reset the transmission control module of your Chevy Silverado when you just replaced it with a new one.
This method involves resetting and teaching your car TCM to function efficiently and effectively.
In the subsequent list, we shall briefly list and explain steps to follow to reset the TCM of your Chevy vehicle:
So, how do you reset a transmission control module?
Follow these steps to reset the TCM.
Step 01: Insert Key and Turn to Position 2
The first step in resetting your Chevy Silverado’s transmission control module is to first slide your key in the ignition and set it to position 2.
In this first step, you do not need to start your vehicle.
Ensure that the dashboard light is lit up.
Also, ensure that your key is indeed positioned to 2.
To do this, listen to the click as you turn the key.
The second click is position 2.
If there are any error lights, they will appear here.
Step 02: Step on the Accelerator Pedal
It is also known as the gas pedal. Place a foot on the pedal and gently press down.
Make sure that you have pressed the pedal down.
Keep your leg on the depressed pedal to activate the kick-down switch, and don’t lift your leg till about 15 to 30 seconds.
Step 03: Turn Off the Key Without Lifting Your Leg From a Pedal
After pressing your key on the pedal for about 15-30 seconds, go ahead and turn off the key.
Do this without lifting your leg from the accelerator pedal.
Once you have shifted the key back to position 0, you have completed step 3 of this reset and are ready for step 4.
Step 04: Release the Acceleration Pedal.
Remember to turn your key to position zero before performing this step.
Failure to do this will mean you will have to start this procedure again to work effectively.
Now, if you wonder whether to remove your foot from the pedal slowly or hurriedly do so, there are no worries here.
There is no specific way to remove your foot here, so feel free to pick any method as long as the key is turned to position zero before taking your foot off the pedal.
That being done, we can move to the next step.
This step will require your patience.
Step 05: Wait Patiently
It’s time to test your patience. The waiting period allows your Chevy Silverado to rest and simplify the procedure.
The rest period will usually take 3-5 minutes.
Any longer could mean that there is a physical fault on the TCM.
Make sure to take note of the waiting period.
It is important to emphasize that your car key is left in the ignition hole and put in position zero during this step.
If you have mistakenly removed the key during this process, you can just carefully insert the key and start this process.
You may experience some delay, but that is okay.
Step 06: Drive and Calibrate
The last step to reset the TCM of your Chevy Silverado is to drive the vehicle.
Don’t get scared about the calibration.
Calibration is just a way of your vehicle telling its system and sensors to re-adjust and reset to work efficiently.
At this stage, we can say that your Chevy Silverado re-learns how you drive and control the vehicle.
The drive is expected to last between 10-15 minutes for the car to learn your driving method completely.
Take your time to drive slowly and allow your car to adapt carefully.
Compare this process to teaching a child how to walk.
However, you don’t need to take months to teach your car how to drive properly.
Just take it easy.
We also recommend keeping to a specific speed and avoiding acceleration during this final stage.
If there is no physical damage to your Chevy Silverado TCM, this method should easily solve the issue.
You can start driving your car as nothing happened.
What Causes the Vehicle’s TCM to Have Problems?
Many things could damage the transmission control module of your Chevy Silverado.
Firstly, excessive vibration can reduce the lifespan and, therefore, damage your TCM.
TCM is usually bolted on the vehicle chassis, and too much vibration will put excessive stress on the bolt, later leading to damage.
Many design analysts and engineers have argued that this vibration could lead to fatigue in the TCM.
Secondly, water getting into the transmission control module could lead to short and eventual damage to the TCM.
Where there is water damage to your TCM, you may need to replace the TCM of your Chevy Silverado.
Next, Voltage overload could cause damage to your TCM.
This occurs when more voltage than the TCM is designed to carry is let into the device.
This will usually cause burnout or circuit burnout.
A repair could be done, but you will be required to replace the TCM in most cases.
Finally, when a short solenoid occurs.
This is the opposite of Overload.
This occurred when a lower voltage than the TCM was designed to damage the solenoid found in the TCM.
