Before you can reset your transmission control module, it’s important to know what it is and how it affects your car overall. First, it is responsible for collecting data and processes the signals being sent to your transmission to regulate the transmission’s shifting gears. It works with many parts of the car, which also relies on its functionality. These parts of your car include the engine, brake pedal position sensor, transmission fluid temp sensor, turbine sensor, and throttle position sensor. Without it, you wouldn’t be able to switch gears effectively and consistently, which can cause accidents if not taken care of.
Spotting the problem beforehand can help you determine if it’s time to learn how to do the transmission control module reset. Before changing it to a new one, try resetting it first to help you save money while making it brand new.
The Signs & Causes of a Bad Transmission Control Module
There are several reasons why a transmission control module could go bad. It can be caused by any of the following:
- A voltage overload
- Vibration or thermal stress
- Shortcircuit in the circuits
- Shortcircuit in the actuator or solenoid circuits
- Shortcircuit caused by water in the circuits
You can spot the problems before it gets worse by looking out for the following signs:
- Difficulty in downshifting when slowing down or coming to a stop
- Difficulty in upshifting when accelerating or manually trying to upshift
- Difficulty in shifting or you can’t shift to neutral
- The transmission shifts to neutral or another gear on its own
- There’s a delay when trying to switch gears
If you are experiencing any of the problems above and it seems to not go away after a few days, there may be a problem with the transmission control module. This is where resetting may help.
Resetting the Transmission Control Module by Yourself
First, you need to turn the key position to two. Check the dashboard headlights if it’s on. If it is, go to the next step which is to step on the gas pedal, then the accelerator pedal. Doing so will activate the kick-down switch. Do not take the pressure off the gas pedal and wait for 10 seconds for the full reset process to be finished. Next, turn the key to the home position, but don’t release the pedal just yet. Remember this because it is an important step.
Once the key is turned to the home position, you can release the gas pedal. But ensure that you don’t take the key off the ignition as well. Give the engine some little time to rest. About 2 to 3 minutes is enough. Lastly, go for a 15-minute ride to familiarize your engine with how you drive.
