Voltage overload is one of the most common reasons why a TCM can go bad.

This happens when the circuit of either a solenoid or actuator has a short.

Another reason is corrosion that may manage to build up inside the TCM as a result of water, when water gets in, the circuits get shorted out and the TCM electrical component gets harmed.

When there are tiny cracks in the TCM boards due to thermal stress and vibrations.

All these and others we are unable to mention can make a TCM go bad.

How do I know if my transmission control module (TCM) is bad?

You will know your transmission control module is bad when you notice any of the combinations of the following.

  • Your transmission switches gears without a form warning
  • Inability to shift gear
  • Check engine light keeps coming on
  • Stalling engine on gear shifting etc.
