What Is a Transmission Control Module or TCM
The vehicle’s transmission system allows transferring the force and power from the engine to the wheels using mechanical elements. With sufficient power, the wheels will move the car in the desired direction and speed. However, the performance and energy optimization of the moving vehicle is controlled by an electronic component known as the TCM or Transmission Control Module.
The Transmission Control Module is an integral part of the vehicle’s electronic system, with which they have correctly used power and speed.
This electronic module receives information from the vehicle’s onboard computer and regulates the precise moment to change gear or speed.
Using other parameters that indicate the moment’s demand, either conditioned by the terrain type, speed, load, or weight carried. In other words, it takes into account the driving conditions.
The transmission control module warns of faults. Depending on the type of vehicle, it can limit the vehicle’s speed or block the system to prevent further damage. It is essential to visit a specialized workshop. The accelerator pedal, turbine, throttle position, and transmission fluid temperature sensor work with the TCM.
Steps to Resetting Transmission Control Module
Here are the steps on how to reset transmission control module chevy:
Step 1. Turning Key Position
Before resetting the transmission control module, it is necessary to check the key position. To begin with, you must change the key position to 2. Check that the dashboard lights are on.
However, stepping on the accelerator and starting the car in the first step is not necessary. Be careful when setting the ‘KEY’ position to the correct number.
Keep an attentive ear; there will be two clicks. At the same time, the dashboard lights will illuminate. You should not start the engine yet.
Step 2. Press the gas pedal
Once you have finished the previous step, you must step on the accelerator pedal. Make sure you press it down.
Depress the accelerator pedal to activate the kick-down switch. Keep depressing the pedal and continue to the next step.
Step 3. Keep Waiting
You must be patient if you have come here to reset your Chevy’s transmission control module.
All you need to do during this period is to stay for about 15 seconds depressing the pedal, which will be enough for the accelerator pedal to start working for the complete reset procedure.
Step 4. Turning the Key Off
After putting your foot on the accelerator pedal for about 10-12 seconds, you need to go ahead and return to the key. However, do not let go of the pedal.
It would be best to do all this “resetting” by keeping your foot on the pedal. Remember before you had the keys turned to 2? You must go through it and return it to its previous position.
All you have to do is turn them off. With your hands, turn the key to zero. After turning the key to its previous position, you must keep it.
Step 5. Releasing Gas Pedal
Once you have turned the key to the home position, you can release the accelerator pedal. Ensure you have kept your foot on the pedal throughout the previous step.
And only release the accelerator pedal when you have finished turning the key to the zero position.
Step 6. Wait Again
We realize that you do not want to wait. However, the restart process takes a little time. You must rest your Chevy after taking your foot off the accelerator.
Your engine should be off for approximately 5 minutes. Check that the ignition key is in the off position. Do not change the key. Take your time!
Step 7. Ready
You are practically done with the procedure. You have done the Engine Control Unit (ECU) and the Transmission Control Unit (TCM).
All you need to do now is drive! When done with the TCU and ECU programming, you should take your car for a drive. The drive should take about 20 minutes. The TCU process, along with the ECU, will undoubtedly work cooperatively.
They will try to learn your driving technique. They will certainly check your driving pattern and take care of that.
Signs and Symptoms of a Bad Transmission Control Module
How do I know if my transmission control module (TCM) is wrong? There are several symptoms that your transmission control module is malfunctioning that is usually ignored.
If you have seen any of these symptoms, your Chevy’s TCM may be damaged:
- Unpredictable shifting
- Difficulties Shifting into Higher Gears
- Downshifting problems
- Delayed shifting
- Poor fuel economy
- The transmission does not shift gears when stationary.
- The transmission does not upshift when accelerating.
- The car is stuck in neutral or first gear.
- Not shifting gears
- Check Engine Light
Where Is Transmission Control Module Located
The transmission control module is usually located at the rear of the transmission case, precisely under the cover. It is located below the engine control module.
On some models, it can also be found under the hood near the battery or the interior center console.
4l60e Transmission Control Module Location
The latest generation 4l60-E transmission has three cast aluminum alloy parts: hood, main body, and rear cover. GM reduced the package to 21.9″ long, equivalent to a 15.4″ manual transmission.
The input shaft has 30 slots. The automatic transmission usually has its cooling inlet on the right side with a square oil reservoir.
The key distinction of the 4L60E automatic transmission (1997-2006) from the early 4L60E (1992-1997) or 4L60 (1990-1992) or 700R4 (1982- 1989) is the “six hex bolts” of the rear output or rear cover.
The 4L60E transmission module can be found in the back of almost all GM vehicles, including C/K Truck, Sonoma, Chevy Silverado, Jimmy, Tahoe, Yukon, Astro, Safari, Suburban, Silverado, Blazer, Bravada, Firebird, Camaro, Corvette.
What makes a TCM go bad?
Damage to the transmission control module is usually caused by the following:
- Voltage overload
- Short circuits in the circuits
- Shortcircuit in the actuator or solenoid circuits
- Shortcircuit caused by water in the circuitry
- Vibration and thermal stress.
Will a bad TCM throw a code?
Yes, an ODB-II scanner will throw some error codes specific to a faulty Transmission Control Module (TCM), including legends such as P0613, p0700 transmission control system, P0706, ETC.

How do you fix a Chevy P0700?
The P0700 code indicates a problem with the transmission control system. The first step is to check the level and condition of the transmission fluid. If the fluid is low or dirty, it should be replaced.
The next step is to check for any loose or damaged wiring. If any wiring is found, it should be repaired or replaced. Finally, the transmission control module should be reset or, failing that, replaced.
How serious is a P0700?
P0700 is a diagnostic trouble code (DTC) that indicates that a problem has been detected in the transmission control system (TCS). The TCS is responsible for controlling the gears in the transmission, and the P0700 code indicates a problem with the TCS itself.
The most common cause of a P0700 code is a faulty transmission control module (TCM), but a defective transmission, a faulty shift solenoid, or a faulty speed sensor can also cause it.
If other codes accompany the P0700 code, it is essential to diagnose and repair them first, as they may cause the P0700 code.
Does a TCM need to be programmed?
If a new TCM is installed, it is necessary to program the transmission control module, and the programming must be done on the car’s computer.
Side Note: You should never attempt to service the vehicle if you have already installed a new transmission control module, as this could cause premature automatic transmission failure.
Reprogram Transmission Control Module
How do you reprogram a transmission control module? Reprogramming the TCM is a reasonably simple process, but it should be left to the professionals. If you try to do it yourself, you could end up causing more damage to your transmission.
The first step in reprogramming the TCM is to turn the car on. Once the vehicle is on, you will need to shift through the gears several times. You will need to change through the gears twice on an automatic transmission. If the information is manual, you must shift between gears and reverse three times. After moving several times, the TCM will automatically reset.
Once the TCM has reset, you must drive the car for at least 10 miles. This will allow the TCM to relearn your driving habits and adjust the shift points accordingly.
How much does it cost to replace a TCM?
The cost to replace a transmission control module will be in the $500 to $1000 range.
Also, expect part costs in the $400 to $700 range. But for all that, you can also order a new transmission control module (TCM) online and ask them for their rates for the job.
What does lost communication with TCM mean?
Diagnostic Trouble Code (DTC) U0101 shows that contact with the TCM has been lost. This code is displayed when the TCM does not accept or transmit a response via the CAN bus. The TCM is the computer that controls the vehicle’s transmission.

If your Chevy Silverado displays error code U0101, the transmission control module (TCM) cannot communicate with other vehicle control modules. This can be a severe problem, as it can prevent the transmission from shifting correctly or even cause the engine to stall.
How do you reset a Chevy TCM?
To reset the TCM, I turn the key to the ON position, step on the accelerator pedal for 10 seconds, turn off the engine, release the pedal, and wait 5 minutes for the engine to restart.
How do I reset my Chevy ECM?
Remove the negative battery cable nut with a socket wrench or wrench. Remove the battery cable and set it aside.
Turn the headlight switch to the “on” position to drain the remaining power from the ECM. Wait 10 minutes before turning it back to the “off” position.
How do you reset a transmission control module?
It is not uncommon for the transmission control module (TCM) to fail. When this occurs, it is often necessary to reset the TCM to get the transmission working correctly again. The TCM is responsible for controlling the transmission and its various functions.
When it fails, the transmission may not shift correctly or at all. To reset the TCM, it is necessary to disconnect power for more than five minutes. Once the power is reconnected, it will be required to reprogram the TCM. This can be done by a qualified mechanic or transmission specialist.
Will disconnecting the battery reset TCM?
Will disconnecting the battery reset the transmission? Disconnecting the battery would not return the TCM to its default settings, and you would need to use a transmission scan method. Disconnecting the battery terminals will not complete the phase or solve the gear shift issue.
How long does it take to reprogram a transmission control module?
Reprogramming a transmission control module usually takes 30 to 40 minutes. Programming is completed once the machine has finished loading. The data is passed to the PCM memory chip.
What does resetting the transmission control module do?
When the transmission control module is reset, the adaptive transmission memory is reset, i.e., the driving habits acquired during vehicle use are erased. Therefore, when the TCM is reset, the driving habits are relearned.
What does a transmission control solenoid do?
They regulate the flow of transmission fluid throughout the transmission and add or relieve transmission system pressure.
How to reset the 4l60e transmission?
To reset the 4l60e TCM, follow the standard Chevy TCM steps: turn the key to the ON position, press the accelerator pedal for 10 seconds, turn off the engine, release the accelerator pedal and wait 5 minutes.
What would cause a 4l60e transmission not to shift?
Shift failures on the 4L60E can often be due to a faulty throttle position sensor (TPS). Test the sensor to see if it is functioning correctly.
Is there a way to reset a transmission control module?
The TCM can be reset in several ways. One way is to disconnect the battery and reconnect it after a few minutes. This will reset the TCM, and the transmission will operate normally.
It is important to note that resetting the TCM should only be done as a last resort. If the TCM is not functioning properly, it should be replaced.
How do I test a TCM module?
One way to test the TCM module is to use a multimeter. First, disconnect the TCM module from the vehicle. Next, set the multimeter to the ohms setting and place the probes on the TCM module terminals. The TCM module should have continuity between the terminals. If there is no continuity, the TCM module is probably defective.
