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.

Questions and answers
| Is the part new? |
|---|
| The instrument cluster is used, and the glass and housing may show signs of use (scratches). Ask about the condition before buying. It comes with a 6-month warranty. |
| Can I fit an instrument cluster from a different engine version? |
| We do not assume so. Clusters differ in rev counter range, warning lights and software, so compare the numbers and the engine version. |
| Why does the number have several spellings? |
| The same number may be written on the label with spaces, dashes or as one string. We give both forms to make it easier to find. |
