What Is a Transmission Control Module or TCM?
The transmission system mechanically transfers engine power to the wheels. With enough power, the wheels will drive the car. TCMs, or Transmission Control Modules, optimize vehicle performance and energy use.
The transmission control module helps the vehicle utilize power and speed correctly. This electronic module controls gear and speed changes based on vehicle computer data.
Using other characteristics to indicate demand, such as terrain type, speed, load, or weight. It considers driving circumstances.
Transmission control modules report problems. Depending on the vehicle, it might limit speed or block the system to prevent harm. A specialist workshop is necessary. The TCM controls the accelerator pedal, turbine, throttle position, and transmission fluid temperature sensor.
How To Reset 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 are 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 hood, main body, and rear cover of the newest 4l60-E transmission are cast aluminum alloy. GM decreased the package to 21.9′′, which is 15.4′′ manual transmission length. 30 slots are on the input shaft. The automatic transmission has a square oil reservoir and a right-side cooling inlet.
The “six hex bolts” of the rear output or rear cover distinguish the 1997-2006 4L60E automatic transmission from the early 4L60E (1992-1997), 4L60 (1990-1992), and 700R4 (1982-1989).
C/K Truck, Sonoma, Chevy Silverado, Jimmy, Tahoe, Yukon, Astro, Safari, Suburban, Silverado, Blazer, Bravada, Firebird, Camaro, and Corvette all have the 4L60E transmission module in the back.
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 controls 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.
