How To Reprogram Your Dodge TCM?
To reprogram your Dodge TCM, insert the key into the ignition and turn it twice. Press the gas pedal down and hold it for 5-10 seconds. Now turn the key off, release the pedal, wait patiently for 5 minutes, then drive your car normally.
A TCM is a device or computer the engine uses to control an automatic transmission. The TCM uses sensors and data from the engine control unit (ECM) to determine the ideal time to shift gears. When this device malfunctions, your driving experience will certainly be affected. A bad transmission control can sometimes be a safety hazard.
Fortunately, a reset can fix several problems with the TCM. What does resetting transmission control module do? The module learns the user’s driving habits (adaptations) and then controls the shifting accordingly. Therefore, a reset erases these adaptations learned from previous uses and allows the computer to start afresh.
A dealer or authorized service center with proper transmission control module programming tools (scanner and software) will usually reset TCM for you. That is after servicing your car or replacing the tranny. However, as mentioned, you can also reset the system at home to fix issues affecting your transmission.
– Conditions To Fulfill Before Resetting TCM
To reset the module, Dodge instructs that the following conditions must be fulfilled:
- During the relearning procedure, you must apply the brakes
- The engine speed must be more than 500 RPM
- Ensure the throttle angle is less than 3 degrees
- The shift lever must stay in the park until you’re prompted to overdrive
- The shift must stay in the new overdrive until the completion of the DBRT
- The oil temperature needs to remain above 60 degrees and below 200 degrees
Let’s now get into the details so you can find out “how to reset transmission control module Dodge Ram 1500”. You won’t need any tools. Just grab your car key and sit in the driver’s seat.
1. Insert the Key Into Ignition and Turn It Twice
With your vehicle parked and the engine off, insert the key into the ignition and turn it twice (accessory mode). That will turn the dashboard lights on, but the engine won’t start.
You should hear a couple of clicks while you rotate your key. The engine must not start. Wait for at least 10 seconds before trying the next step.
2. Press Gas Pedal to the Floor and Turn off the Ignition
Push the accelerator pedal slowly until it reaches the end (to the floor). You’ll now hold it at that position for between 15 and 30 seconds. While still holding the accelerator, turn the key to the off position. Please don’t take it out of the ignition yet.
3. Release the Accelerator and Wait Patiently
With the ignition off, release the accelerator pedal. Now wait patiently, at least 5 minutes. During this time, you won’t touch any electronics in the car. Don’t open a door, either.
Just sit. After waiting 5 minutes, turn the engine on and drive your car normally for about 30 minutes. As you drive, your reset module will relearn your driving habits to continue giving you the smooth driving experience you want. You can repeat the procedure if you’re still experiencing transmission problems.
In most cases, there will be a significant difference after the reset unless something else is wrong. The procedure itself often takes about 7 minutes to complete. But as mentioned, you’ll need to relearn the module by driving your car for approximately half an hour. Generally, you should spend less than 40 minutes overall.
As mentioned, you can also reprogram your Dodge TCM by disconnecting the battery. Open the hood, locate the battery, and identify its negative terminal. Using a wrench or pliers, loosen the nuts holding the terminal and then remove it. Wait for at least 20 seconds before replacing the terminal. The battery reset forces force the engine control unit (ECU) to reset and, in the process, reset the TCM.
Disconnecting the battery can apply on other models in case you’re wondering how to reset transmission control module, Chrysler. The method is applicable if you also want to find out how to reset transmission control module, GMC.
How To Know if Your TCM Is Failing?
To know if your TCM is failing, observe the obvious symptoms, which include erratic gear shifting. The check engine warning light will often turn on whenever the module malfunctions. Other telltale signs are delayed shifting and getting stuck in one gear.
Before we dive into the details, let’s mention the common triggers of a TCM failure. One is general wear and tear due to continued use and aging. As you put more mileage on your car, various components will wear out and eventually fail.
Another notorious cause of TCM malfunctioning is excessive heat from the engine. As mentioned, the TCM is a computer. It includes electronics, which are vulnerable to heat damage. The module has a plastic and metallic encasing to protect it against heat, but the casing can fail.
A transmission control module may fail prematurely if its circuitry has soldering faults. Faulty wiring between the module and other controls in the vehicle can trigger the malfunction. Wiring issues can occur due to amperage overload or wear and tear. Last but not least, engine vibration can cause a TCM to fail.
Most of these triggers are things beyond your control. But, it’s essential to recognize the signs of a failing TCM early enough and act accordingly. Here are the details:
It can be annoying and risky if your car shifts when you didn’t intend it to. A faulty TCM could also cause the transmission to shift into gears you didn’t want. For instance, you may drive at high speed, and your vehicle abruptly shifts into a low gear or neutral without reason. That indicates that the module has a problem.
Check the Engine Light On
The Check engine light can turn on to indicate many problems in your engine. One of them includes a failing transmission control module. So, if the light turns on after you’ve experienced some transmission problems, it would be best to have your TCM checked.
Delayed gear shifting is another obvious symptom of a problematic TCM. You accelerate, and the engine is revved but delays shifting into gear. The problem means that your transmission is struggling to upshift or downshift.
As mentioned, the TCM determines the best time to change gears. If there are delays or struggles, the component is malfunctioning. You need to check it and act accordingly.
Stuck in the Same Gear
Unpredictable and delayed shifting problems are bad, but being stuck in the same gear is the worst. That can happen when your TCM fails due to several issues, including leaking transmission fluid within the system. You could get stuck in the first gear or neutral, meaning you can only drive slow or not move at all.
If resetting the TCM doesn’t fix the issues you’re experiencing, it may be time to replace the faulty part. The replacement cost ranges from $500 to $1000+, depending on the model of your vehicle. You can save on labor costs if you replace the part yourself.
