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 role of the alternator in a car
While driving it is the alternator, not the battery, that powers the lights, injection, fans and electronics. The battery is mainly used for starting and as a backup supply. It is also a good idea to check the battery, as a weak battery can look like an alternator fault.
When the alternator needs replacing
- the charging voltage is too low or too high,
- the ribbed belt squeals,
- the lights are weak at idle,
- the on-board computer reports a charging system fault.
If the battery is very worn, have it tested together with the alternator, as a weak battery puts extra load on the charging system.
Matching by numbers
Compare the full number 2542851B with the number on your alternator. Different versions were fitted to the same models, so the number decides, not the model alone. Before buying, compare the numbers with the marking on your alternator, written with spaces and in full.
