What Exactly is a Transmission Control Module?
The transmission control module is used in controlling electronic automatic transmissions.
It is responsible for calculating the right time and also a place to shift gears so your rides can be uneventful. It is a vital link between your car transmission system and your engine, without this feature, your automatic transmission vehicle will find it pretty difficult to change gears when required.
It makes use of sensors from vehicles and data provided by the engine control unit to give your vehicle optimum performance, fuel economy, and shift quality. I
It is a vital component of your vehicle and it comes in most modern vehicles.
How to Reset Your Transmission Control Module
The transmission control module issues can sometimes be expensive to fix and hence you can attempt doing the repairs yourself.
The number of parts that can go wrong with the transmission control module is fairly high but they are all essential to your vehicle’s properly-functioning well.
It is imperative the TCM works well as it is responsible for interpreting electrical signals from the sensors in other vehicle parts.
The following steps are how you can reset the TCM, you may need a software or a transmission scan to restore TCM to a default setup.
- Move your vehicle shifter to park
- Start your vehicle engine and let it warm up a bit to the normal temperature
- Turn the key in the ignition to the off position and then wait for 5 seconds
- Turn the key back to on position without starting the car
- Check for the A/T check light, it should at least come on for two seconds
- Turn key to the Off position and then to the ACC position
- Press and hold down the accelerator pedal to the floor
- Press the brake pedal, then move the shifter to D, and turn the key back to the on position without starting the car still
- Wait for about 3 seconds, then move the shifter to gear 2, release the gas and brake pedal, then move the shifter to first gear
- Press and hold the brake pedal, and press and release the gas pedal, after that, you should notice the A/T check light flashing on and off.
- Put the shifter in park, and turn it off, after a while has it turned on, this will reset the TCM.
4l60e Transmission Control Module Location
It is located on the rear of the transmission case, directly under its covers, it is just beneath the engine control module or may also be found at the center console inside as car, or near the battery depending on the vehicle type.
What makes a TCM go bad?
Voltage overload is one of the most common reasons why a TCM can go bad.
This happens when the circuit of either a solenoid or actuator has a short.
Another reason is corrosion that may manage to build up inside the TCM as a result of water, when water gets in, the circuits get shorted out and the TCM electrical component gets harmed.
When there are tiny cracks in the TCM boards due to thermal stress and vibrations.
All these and others we are unable to mention can make a TCM go bad.
How do I know if my transmission control module (TCM) is bad?
You will know your transmission control module is bad when you notice any of the combinations of the following.
- Slow acceleration, when it is quite slow to accelerate, know there is something wrong with your TCM
- Poor fuel economy
- Your transmission switches gears without a form warning
- Inability to shift gear
- Check engine light keeps coming on
- Stalling engine on gear shifting etc.
Will a bad TCM throw a code?
Yes, a bad TCM will throw some error code and some of these codes are the pcodes.
PO613, PO700, PO706, etc.
Does a TCM need to be programmed?
Yes, all vehicle TCM needs to be programmed for the specific VIN of the vehicle. You might be asking what will happen if it is not programmed for your vehicle
What happens is that you may most likely get a TCM that mismatch the VIN code of your vehicle and this will throw an error making your vehicle not start, let alone run.
How much does it cost to replace a TCM?
Replacing a TCM will cost between $500 to $900 and $450 to $700 for the parts.
The labor fee will cost around $50 to $200. You can even go online to order a new TCM yourself, then engage the services of a professional mechanic to have it replaced for you for a fee of course.
What does lost communication with TCM mean?
Lost communication with TCM means the modules that are meant to communicate with the TCM through the CAN bus/ controller area network are not communicating.
A problem with either the CAN bus, a bad TCM circuit, a faulty TCM, or a dead battery might be responsible for the loss in communication between that TCM and one or two modules.

How do I reset my Chevy ECM?
Simply disconnecting the negative terminal cable of the battery and letting it sit without power for at least 10 to 15 minutes should be right enough to reset the Chevy ECM.
Resetting a car ECU will help fix any problem that may be wrong with it as it will set the ECU right back to its default status.
You can start the process by sliding the negative cable off of the battery and setting it aside, putting on the headlight switch to enable all the power to drain from the ECU, waiting for 10 minutes before putting the headlight back off, and have the negative cable replaced. You are good to go.
Will disconnecting the battery reset TCM?
Nope, just simply disconnecting the battery will not solve all the problems faced by the TCM.
To reset the TCM you will need a transmission scanner or software to completely reset the TCM.
How long does it take to reprogram a transmission control module?
Armed with the right tool and right information, the reprogramming control module process will take anywhere between 30 minutes to an hour depending on the vehicle’s make and model.
What does a transmission control solenoid do?
The transmission contr solenoid is responsible for controlling transmission fluids by opening and closing when they receive an electrical signal within the transmission system.
They are electro-hydraulic valves and are in charge of how the transmission fluid flows throughout the transmission system.
