A faulty transmission control module (TCM) most often causes limp mode with the gearbox stuck in one gear, harsh jolts when you select D or R, erratic gear changes, flashing PRND letters and a gearbox or engine warning light. However, the same symptoms are often caused by a low gearbox oil level, a weak battery, a poor earth or a faulty sensor. To test a transmission control module, start by checking the battery and reading the fault codes with a diagnostic tool that can talk to the gearbox control unit, then check the power supply, the connector, the oil and the live data. Below we explain the symptoms, the diagnostic steps and what the most common fault codes mean.

Signs of a faulty panel
- the panel does not respond to button presses,
- the airflow does not change direction or strength,
- the display shows wrong values or goes dark,
- settings are not saved after the ignition is switched off.
Inspect the connector at the back of the panel: burnt or green contacts cause symptoms similar to damaged electronics.
