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.

Control unit variant
This listing is for a control unit in the following variant(s): VIRGIN. We describe the differences between the variants (locked, unlocked, Virgin, IMMO OFF, Plug and Play, clone, full set) on the ECU preparation options page. Before buying, send us the numbers from the label and we will confirm which variant is available for that number.
According to the listing, this is a control unit in the Virgin version, meaning it has been cleared of data from the previous vehicle and prepared for reprogramming. After fitting, it requires programming, coding or adaptation using suitable equipment.
When an engine control unit needs replacing
- the engine warning light comes on and does not go out,
- the diagnostic tester cannot connect to the control unit,
- control unit communication or power supply errors appear in the fault memory,
- the housing or connector of the control unit shows signs of water ingress or corrosion.
First check the battery, fuses and wiring, because a faulty control unit has to be distinguished from an ordinary fault in the electrical system. Fitting and configuration are best left to a garage with suitable equipment.
