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 to recognise a faulty alternator
- the battery charging warning light is on,
- the battery goes flat even though you drive,
- the lights dim at low revs,
- the electronics work intermittently.
If the battery is very worn, have it tested together with the alternator, as a weak battery puts extra load on the charging system.
