Steps to Resetting Transmission Control Module

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 by means of mechanical elements. With sufficient power, the wheels will move the vehicle 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 achieved the proper use of power and speed.

This electronic module receives information from the vehicle’s onboard computer and regulates at what precise moment to change gear or speed.

Using other parameters that indicate the demand of the moment, either conditioned by the type of terrain, speed, load, or weight carried. In other words, taking 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, it is not necessary to step on the accelerator and start the car in the first step. 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 with the previous step, now you just have to step on the accelerator pedal. Make sure you press it all the way down.

Depress the accelerator pedal all the way down to activate the kick-down switch. Keep depressing the pedal and continue to the next step.

Step 3. Keep Waiting

Now, if you have come here to reset your Chevy’s transmission control module, you need to be patient.

All you need to do during this time period is to stay for about 15 seconds depressing the pedal, which will be enough for the accelerator pedal to start working for the full 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.

Note that you have to do all this “resetting” by keeping your foot on the pedal. Remember before you had the keys turned to 2? Yes, now you have to 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 the key there.

Step 5. Releasing Gas Pedal

Once you have turned the key to the home position, you can release the accelerator pedal. Make sure 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 give your Chevy a rest 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 actually done the Engine Control Unit (ECU) process along with the Transmission Control Unit (TCM) process.

All you need to do now is drive! When done with the TCU as well as 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 certainly work cooperatively.

They will try to learn your driving technique. They will certainly check your driving pattern and take care of that as well.

What Causes a Transmission to Get Stuck in Gear

Signs and Symptoms of a Bad Transmission Control Module

How do I know if my transmission control module (TCM) is bad? there are a number of symptoms that your transmission control module is malfunctioning that is normally 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

4l60e Transmission Control Module Location

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 under the interior center console.

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, and Corvette.

Where is the transmission control module located?

The location of the transmission control module depends on the type of car it is in. In most cars, is often found at the rear of the transmission case, under the engine control module, or under or near the steering wheel.

What makes a TCM go bad?

Damage to the transmission control module is usually caused by:

  • Voltage overload
  • Short circuit in the circuits
  • Shortcircuit in the actuator or solenoid circuits
  • Shortcircuit caused by water in the circuitry
  • Vibration and/or thermal stress.

Will a bad TCM throw a code?

Yes, if you use an ODB-II scanner, it will throw some error codes specific to a faulty Transmission Control Module (TCM), including codes such as P0613, p0700 transmission control system, P0706, ETC.

How do I fix code p0700 – Article that might be useful if you see this type of error

How do you fix a Chevy P0700?

The P0700 code indicates that there is 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 that there is a problem with the TCS itself.

The most common cause of a P0700 code is a faulty transmission control module (TCM), but it can also be caused by a faulty transmission, a faulty shift solenoid, or a faulty speed sensor.

If the P0700 code is accompanied by other codes, it is important to diagnose and repair those codes first, as they may be the cause of 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 failure of the automatic transmission.

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 what their rates are for the job.

What does lost communication with TCM mean?

Diagnostic Trouble Code (DTC) U0101 shows that contact with the TCM has been lost. When the TCM does not accept or transmit a response via the CAN bus, this code is displayed. The TCM is the computer that controls the vehicle’s transmission.

U0101 code is usually caused by one of the following factors: The battery is almost empty. A faulty TCM. The TCM circuit is malfunctioning.

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 accelerator 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 at least 10 minutes before turning it back to the “off” position.

FAQs

Will disconnecting battery reset TCM?

Disconnecting the battery would not return the TCM to its default settings, and you would need to use a transmission scan method to do so. Simply 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 transmission adaptive 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 4l60e transmission?

To reset the 4l60e TCM, just follow the standard Chevy TCM steps: turn the key to the ON position, press the accelerator pedal for 10 seconds, turn off the engine, and 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 properly.

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 you program a transmission control module?

To reprogram a transmission control module, disconnect the battery terminals and let the system drain for 5-30 minutes. Reconnect the battery, and the TCM should be reset.

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.

Conclusion

Now that you understand exactly how to reset the transmission control module, you’ll definitely never get tired of the same gearbox! The method our experts have pointed out is tremendously easy. All you need to do is keep the warnings in your mind, as well as do your best.

It certainly won’t take you much more than 10 minutes to finish the method. After that, you can drive the car for 15 minutes, and it’s done! If none of this works, the best thing to do is to take the car to the mechanic for repair.

  3. Hi Liam, have a 2007 cobalt that only engages in reverse. No drive, intermediate or low. Engine just revs like it’s stuck in neutral. some forums suggest a new TCM No engine light on & no codes on the reader. I’m baffled. Fluid is good & no leaks. wondering if resetting TCM would fix? Any thoughts? Thanks

        • Hmm, I don’t think so, usually, the shudders come from fluid problems in the transmission of the vehicle, but my advice is to go to a trusted mechanic to have it checked out.

    • I have a 2006 HHR how do I know if it’s my transmission if I take off slow it doesn’t jerk if I take off fast it jerks when trying to change gear what do I need to do

  4. I have a 2000 Chevy monte Carlo ss .. 3.8l v6 .. When going to take off it does great .. But when shifting from 1st it has a pause before it goes into 2nd gear .. do you think this is a reset issue or do i have something major going on .. ?? .. Thank you in advance for your time ..

  5. Super quick and easy to follow instructions. I will tell you what happens, it did turn off my check engine light!! Hurray. That’s a plus at least that won’t stress me out anymore. I should have read this article before I bought an intake sensor for $50+

    • Follow up. This was a quick and easy fix for my Terrain. My gas mileage doubled! With no changes made to driving pattern or parts replaced. I don’t know what caused this but I can tell you what fixed it! Thanks author(s)! I am no mechanic, I’m just a girl. A little history on the Terrain, it had been parked for nearly two years and then drove and then drove minimally for the next two years that may have had something to do with it’s performance and pitfalls.

  6. I have an 2016 GMC 3500 that makes a rumbling sound coming from underneath the drivers sid footboard when I put it in reverse only. Do you think this would help? If not, what do you think some possible culprits are? Thanks

  7. Have a 2010 chevy impala wouldn’t change gears. So i changed strainer and Transmission fluid which was black also a little metal was in pan.Gears change now but its got a pause sometimes. Do you think this will work?

  8. On chevy’s I’ve had in the past the problem I’m having now would seem to be a stuck or out of adjustment kick down cable. My vehicle is a 1999 chevy express 1500 van with the 5.7 and when you don’t run it hard it shifts fine but when you floor it it seems like it would run enough RPMS to blow the engine before it would ever shift. I checked advance auto for a kick down cable and it doesn’t list one so does that mean that the kick down cable has been replaced by a transmission control module? Thanks, Bob

  9. I have changed 3 gearbox in my toyota feilder 121chancge 2 ECU, 2 DESHBOARD METER but I have same problem as before as the Gear change the car jerk
