Your vehicle's transmission control module works alongside the engine and the transmission to keep you moving forward. When you're driving, this is the part responsible for calculating the right time and place to change the current gear to make your driving experience smooth.
Aside from this primary responsibility, this control module also sends OBD2 codes to your car's computer if it detects any malfunction or other issues with your transmission. These codes appear as the check engine light on your dash, alerting you that something is not right.
Without a properly working transmission control module, your car would be unable to change gears when needed, leading to severe mechanical issues that require expensive repairs. Proper shift timing helps to improve the overall efficiency of your vehicle.
