The TCM is a computer that controls the transmission. It is responsible for shifting gears and also controls things like engine speed and vehicle speed.
If your car is having trouble shifting gears, it could be a sign that your TCM is failing. A faulty TCM can also lead to poor fuel efficiency as your car struggles to shift gears properly. The process to reset a Mitsubishi TCM can be done at home with a few tools. In this article, we will show you how to reset your TCM in a few simple steps.
How to Reset a Mitsubishi Transmission Control Module – Step-by-Step Instructions

How to Reset a Mitsubishi Transmission Control Module – Reasons Why You Might Need to Do This
If you own a Mitsubishi vehicle with an automatic transmission, you may be wondering how to reset the transmission control module (TCM). There are a few reasons why you might need to do this, and we’ll go over them all in this article.
First, let’s talk about what TCM actually is. The TCM is a computer that controls the transmission. It is responsible for shifting gears and also controls things like engine speed and vehicle speed. If there is a problem with the TCM, it can cause all kinds of problems with the transmission.
One of the reasons you may need to reset the TCM is if the transmission fluid has been changed. When you change the transmission fluid, the TCM must be reset so it can learn the properties of the new fluid. Otherwise, the transmission may not shift correctly or at all.
Another reason you may need to reset the TCM is if the transmission was rebuilt or replaced. In this case, it will be necessary to reset the TCM so that it can learn the properties of the new transmission. Otherwise, the transmission may not shift correctly or may not shift at all.
What Are the Signs of a Bad TCM
There are several signs that can indicate a problem with your TCM, which include:
- Trouble shifting gears: if your car has trouble shifting gears, it could be a sign that your TCM is failing.
- Getting stuck in a gear: if your car gets stuck in a gear and won’t shift, it’s a sure sign that something is wrong with your TCM.
- Poor fuel efficiency: a faulty TCM can also lead to poor fuel efficiency as your car has difficulty shifting gears properly.
What Causes a Used TCM to Fail
As anyone who has owned a car knows, transmission problems are some of the most frustrating and costly problems that can arise. A transmission control module, or TCM, is an electronic device that controls the transmission in your vehicle. In order for your car to function properly, it is important to know how to reset a Mitsubishi transmission control module when necessary.
There are a number of different things that can cause a used TCM to fail. One of the most common causes is simply wear and tear. Over time, TCM components can wear out and stop functioning properly. Another common cause of TCM failure is electrical problems. If there is a problem with your vehicle’s electrical system, the TCM can fail.
FAQs
How do I reset my Mitsubishi CVT transmission?
To reset your Mitsubishi CVT transmission, you will need to follow the steps described in the Special Function section of the MUT-III SE scan tool. First, you will need to hold down the accelerator and brake pedals in the applied position. Next, you will need to execute the “Reset Calibration Value” function. Once this is complete, your CVT transmission will reset and should operate correctly.
How much does it cost to reprogram a transmission control module?
The cost to reprogram a transmission control module (TCM) can range from $75 to over $250. In most cases, your local dealer will be able to handle the reprogramming for you. However, if you have a preferred local repair shop that you trust, they should also be able to do the job.
The TCM is an important piece of equipment on your vehicle, as it helps control the shifting. If it becomes damaged or needs to be replaced, it’s important to get it done as soon as possible so your car can continue to run smoothly.
If you are unsure whether or not your TCM needs to be reprogrammed, the best course of action is to consult with a professional. They will be able to diagnose the problem and tell you what needs to be done to fix it.
How do you check a transmission control module?
The first step is to locate the transmission control module. It can often be found under the cover at the rear of the transmission case, just below the position of the engine control module. Sometimes it is located under the center console inside or even under the hood near the battery or inner fender panel.
Once you have found the transmission control module, you should check its connectors and wiring for signs of damage or wear. If everything looks in good condition, you can test the module using a multimeter to check the voltage. If the module is receiving power, it is probably functioning properly. However, if no power is reaching the module, it will need to be replaced.
Do transmission control modules need to be programmed?
Yes, transmission control modules must be programmed. This is because the module must be able to communicate with the vehicle’s computer to function properly. If the module is not programmed, it will not be able to communicate with the computer and the vehicle will not start or run.
To Conclude
In conclusion, if you are having problems with your automatic transmission, it could be a sign that your TCM is failing. A faulty TCM can lead to poor fuel efficiency and difficulty shifting gears. The process to reset a Mitsubishi TCM is relatively easy and can be done at home with a few tools.
