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.

How this part works
The module is not universal - the same name covers different versions depending on equipment, year and the market where the car was sold.
Which car it is for
- Ford Focus - model
- 1.6 - engine according to the listing
What a fault looks like
- the interior lighting does not switch off,

It is worth reading the fault codes first, because many body faults come from switches or wiring rather than the module itself.
