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.

How do you read the differences between ATE numbers 10.0220-0401.4 and 10.0915-2808.3?
A used, working, original ABS pump and control module unit for an Alfa Romeo. We do not state the model - selection is by part numbers. The ATE pair comes with the part number (OEM) 51983920.
Alfa Romeo: ABS 51983920 with the ATE pair 10.0220 and 10.0915
In this listing we give three numbers: the part number (OEM) 51983920 and two ATE numbers - 10.0220-0401.4 and 10.0915-2808.3. The ABS unit is used, in working order and original, assigned to the Alfa Romeo make. We do not state the model, because selection by part numbers is the only criterion here. The easiest way to compare them with your own is to write them out in a small table side by side.
Breakdown of numbers to compare
- 51983920 - part number (OEM): 51983920
- 10022004014 - ATE number: 10.0220-0401.4
- 10091528083 - ATE number: 10.0915-2808.3
Both ATE numbers begin with 10, but their middle groups of digits differ: 0220-0401 and 0915-2808. This is where it is easiest to make a mistake. Other listings for Alfa Romeo ABS units may be built the same way, but with different groups. We do not say which number refers to the pump and which to the control module.
Symptoms that point to the ABS unit
One of the following situations is often the reason for the search:
- the ABS warning light stays on while driving,
- the tester signals a hydraulic module fault,
- the pump is noisy or does not start at all,
- the ABS switches off a few minutes after starting.
Take it calmly: read the fault codes, check the wheel sensors and their connectors, measure the battery voltage. After replacing the unit, the brake system has to be bled, and sometimes the module needs programming or coding - settle this with the workshop.
