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
- air comes out only at the windscreen or only at the footwell,
- the temperature knob changes nothing in the cabin,
- some LEDs on the panel are dark,
- pressing a button gives a click but nothing happens.
Remember that in some cars the panel must be matched or adapted after replacement - check this for your model.
