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.

Symptoms of a faulty engine control unit
- the engine will not start although the starter motor works and there is fuel,
- the engine idles unevenly or stalls for no obvious reason,
- 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.
Before buying a control unit, read the fault codes with a diagnostic tester and check the power supply, the earth connections and the connector. Damaged sensors, wiring or fuses can cause similar symptoms, and in that case replacing the control unit will not help.
Questions and answers
| Are the make and model of the car enough to choose the part? |
|---|
| No. A single model comes with different versions of the control unit, depending on the engine, the software version and the equipment. The most reliable reference is the number on the original control unit. |
| Does a lit engine warning light always mean a faulty control unit? |
| No. Read the fault codes first, because the cause may be a sensor, the wiring or the power supply. |
| Is this an original control unit? |
| Yes, it is a used original engine control unit, not an aftermarket replacement. You can compare the numbers on the label with the original in your car. |
| Is this a new part? |
| No. We sell used original control units, each one inspected before sale. You will find the warranty period in the product features table. |
