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.

When this is the unit
Here are the situations in which customers look for it:
- the ABS warning light does not go out after starting,
- the tester shows a brake module fault,
- the pump does not switch on or is noisy,

Fault code read-out first. Then the wheel sensors, wiring and fuses. When the fault is in the unit, look for a replacement. After fitting, bleed the brakes. Ask about any coding.
