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.

Common throttle body faults
When the throttle body in a Ford starts to fail, the most common signs are:
- soot from the EGR system on the flap – sticking flap, fault codes stored in the engine control unit,
- failed motor or position sensor – engine warning light, limp mode,
- flap not closing fully – the engine may shake when switched off.
When measurements or fault codes confirm the problem and cleaning has no effect, the throttle body is replaced with one carrying the same number. After replacement, many cars need an adaptation in the engine control unit.
