A transmission control module is an electronic mechanism in a vehicle’s transmission that primarily collects data and processes signals to calculate the best time to change gears. Essentially, it helps facilitate effective and consistent gear shifts. If this component becomes worn down or damaged and you do not resolve the issue, the wiring in your transmission could incur permanent damage, and the safety of your vehicle will be reduced. As such, it is crucial to recognize the symptoms of a bad transmission control module so you can identify and rectify the issue immediately. Below, we will address some of the tell-tale signs that something isn’t quite right with your transmission control module.
Stalling
A common sign that there is something wrong with your transmission control module is when a vehicle stalls between gear changes. If your transmission control module experiences damage as a result of overuse, heat fluctuation, or simply old age, it may not be able to properly determine when to change gears. As a result, stalling will likely occur.
Inability To Change Gears
Another common symptom of a bad transmission control module is an inability to change gears. Rather than simply stalling between gear changes, a severely damaged or ineffective transmission control module may prevent your vehicle from changing gears altogether.
For example, your transmission could get stuck in neutral, you could find yourself unable to downshift when coming to a stop, or your vehicle may not be able to upshift when accelerating. These issues are all a potential indication that there is something wrong with your vehicle's transmission control module.
Gear Slipping
If your vehicle often experiences gear slippage, there could be something wrong with your transmission control module. Gear slipping refers to when your vehicle randomly switches into a different gear without any warning or reason. Due to the obvious dangers that such unforeseen gear changes can pose, it’s important to get your vehicle’s transmission inspected as soon as possible when you experience gear slipping.
Reduced Fuel Economy
If you start to notice that you have to fill up on gas more frequently, your vehicle may be trying to tell you that something is wrong. Often, reductions in fuel economy signal an issue under the hood, such as a faulty transmission control module that reduces the efficiency of engine shifts.
