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.

What the alternator does
Inside the alternator the alternating current is rectified and the regulator controls the charging voltage. This keeps the battery charged and gives the electrical consumers a stable supply. Fitting is best left to a workshop that will measure the charging voltage after the replacement.
Symptoms of 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.
Remember that a loose belt, corroded battery terminals or a bad earth can mimic an alternator fault.
