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.

What an engine control unit does
The module's electronics store fault codes that can be read with a diagnostic tool. They help to establish whether the sensors, the wiring or the control unit itself is to blame. Before buying, it is also worth knowing that the control unit communicates with the car's other modules over the CAN bus, which is why version compatibility matters.
Locked control unit
We offer this control unit in the locked variant only - an unlocked variant cannot be selected in this listing; if you would like us to prepare it, ask us before buying. A locked control unit keeps the previous car's data and immobiliser coding, so it is intended for garages that will unlock, program and match it to the vehicle themselves. The available methods, such as PIN / CAR PASS, Virgin, IMMO OFF, auto-programming or cloning, vary depending on the number, software and immobiliser. See our ECU preparation options and contact us before buying.
Fitment
Our range also includes other control units for this model and engine, with different numbers. Choose by the number on the module, not by the model alone. Before buying, compare all the numbers with the label on your control unit, both with spaces and as a single string.
Symptoms of a faulty control unit
- the engine will not start or cuts out,
- the engine warning light (check engine) is on,
- the control unit does not communicate with diagnostic equipment,
- the car goes into limp mode.
Compare all the numbers with the label on your control unit, as the same engine may have been fitted with several versions of the module.
