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.

Which Bosch and OEM numbers make up this Alfa Romeo ABS unit?
A used, working, original ABS pump and control module unit from an Alfa Romeo vehicle. It is identified by three numbers: Bosch 0265225195 and 0265950087 and part number (OEM) 46840338. We do not state the model - selection by part numbers.
Alfa Romeo: ABS unit Bosch 0265225195 / 0265950087, OEM number 46840338
This listing is for a set made up of an ABS pump and control module, removed from an Alfa Romeo vehicle. The unit is used, working and original. We do not state the model - selection by part numbers. The whole unit is described by three numbers: two from the Bosch family (prefix 0265) and one part number (OEM). Because the unit combines a hydraulic part with electronics, you need all three entries for the comparison, not just a single number.
The number family and how it is written
- 0265225195 - Bosch number: 0 265 225 195
- 46840338 - part number (OEM): 46840338
- 0265950087 - Bosch number: 0 265 950 087
Bosch numbers with the 0265 prefix are written either with spaces or as a string of ten digits - it is the same identifier. We do not assign the numbers the role of pump or control module. Selection is by part numbers, so compare the numbers on your part with the whole list.
When a unit like this is needed
Typical circumstances in which an ABS unit is sought:
- the ABS warning light stays on after the engine starts,
- the tester shows a communication error with the ABS control module,
- a pump or pump power supply fault appears in the fault log,
- the ABS system is switched off while basic braking still works.
Before buying, it is worth ruling out simpler causes. Read the fault codes and check the wheel speed sensors, connectors and fuses. After the unit is replaced, the brake system needs bleeding, and the control module may need configuring by a mechanic with a suitable tester.
