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.

- the diagnostic tester cannot connect to the control unit,
- the engine starts and immediately stalls,
- faults appear and disappear, usually once the engine has warmed up,
- the housing or connector of the control unit shows signs of water ingress or corrosion.
Similar symptoms also occur with faulty sensors, bad fuel or worn spark or glow plugs, so start with diagnostics and only then replace the electronics.
