Signs of a Bad Transmission Control Module

A transmission control module (TCM) is what helps the engine determine when and how to change gears for an ideal driving performance. It does this by taking data from different switches and sensors in your automobile.

So, if something goes wrong with that module, then other parts of the transmission could get damaged. Plus, your safety when driving around Egg Harbor, Atlantic City, and Vineland could be compromised.

That’s why it’s crucial to know what the signs of a bad transmission control module are:

  • Delays with shifting
  • Unpredictable shifting
  • Sluggish performance
  • Check engine light comes on
  • Bad fuel economy

We’ll go over these signs in more detail below, so that you know when to contact Boardwalk Acura for service.

  1. Delays with Shifting
  2. When you shift gears in a vehicle, you activate the clutch, then engage the gear. This happens almost instantly in a properly operating transmission. However, if there’s an issue with the transmission control module, then the gears won’t engage on time. This would result in a delay, almost as if your vehicle was in neutral.

  3. Unpredictable Shifting
  4. An automatic transmission shifts to higher gears when you travel fast and goes to lower gears as you slow down. If your vehicle randomly refuses to downshift, jumps to higher gears, or skips gears, then you’ll want to get the control module looked at as soon as possible.

  5. Sluggish Performance
  6. Signs of a Bad Transmission Control Module

    Adding on to the point above, your overall performance may be affected by a bad transmission control module. Because the gears could cycle too fast or too slowly, it could impact the momentum of your acceleration. This means that you’d lose speed rather than pick it up. Plus, whenever you approach a hill, you may find that shifting becomes even more difficult to do.

  7. Check Engine Light Appears
  8. The check engine light could appear on your dash for a number of reasons. However, if you’re experience shifting issues when the dashboard warning light comes on, then there’s likely a problem with some part of the transmission system.

  9. Bad Fuel Economy
  10. A final sign of a bad transmission control module is bad fuel economy. The combination of good shifting and timing is how you get good fuel economy. If the module messes with that timing, then the engine will need to work harder than normal. That extra effort would result in more fuel being consumed, which means you’d have to visit the gas station more often.
