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 this part does
In many models the module communicates with other control units over the bus, so after replacement it may need coding or matching to the car. CAS (Car Access System) in BMW combines car access with engine starting, so after replacement the keys usually have to be programmed.
How to choose the part
For this model we offer several parts that differ in their numbers. The number on the label decides, not the model name alone.
When to replace the part
- the battery drains overnight for no obvious reason,
- door signalling works incorrectly,
- the interior lighting does not switch off,
- nothing happens when settings are changed.
It is worth reading the fault codes first, because many body faults come from switches or wiring rather than the module itself.
