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.

The listing does not state the car model or year, so we do not give them in the description and match the part by its numbers.
Part numbers for S110130050A
The numbers as written in the listing and as a single string, the way catalogues list them:
- S110130050A, control unit manufacturer's number,

The ending of a number often indicates a different version of the control unit, so compare every character. If you are in doubt, write to us before buying.
What can point to an engine control unit failure
- the diagnostic tester cannot connect to the control unit,
- the car loses power or goes into limp mode,
- fuel consumption rises for no obvious reason,
- 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.
