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 can you check whether numbers 0265216531 and 0273004337 match your part?
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. Compare the three numbers in the listing with what you have to hand.
Alfa Romeo: ABS unit Bosch 0265216531 / 0273004337 - number comparison
This listing is based on three numbers: two Bosch numbers (0265216531 and 0273004337) and one part number (OEM) 46479194. It is a used, working and original unit for an Alfa Romeo. We do not state the model - selection by part numbers. The surest method is simple: write down the numbers from your part and hold them up against the list below, one under the other.
Three numbers to hold up against your part
- 0265216531 - Bosch number: 0265216531
- 46479194 - part number (OEM): 46479194
- 0273004337 - Bosch number: 0273004337
Similarly built ABS unit listings for Alfa Romeo usually differ in the endings of the numbers, not in the beginnings. Here, what counts are the last three digits of both Bosch numbers: 531 and 337. A match on the start of a number is not enough - compare the whole string. We do not assign the numbers the role of pump or control module.
Situations in which a unit like this is sought
One of these situations usually prompts a comparison of numbers:
- the ABS warning light comes on and stays on,
- diagnostics show a hydraulic module or control module fault,
- the ABS pump shows no sign of working when the ignition is switched on,
- the ABS system switches off while basic braking works.
Before you order the part, carefully rule out simpler causes: read the fault codes, inspect the wheel sensors and their wiring, check the fuses and the condition of the battery. After replacement the brake system needs bleeding, and sometimes also adaptation with a tester - ask your workshop about this.
Most common questions about the numbers
| Do I have to match all three numbers at once? |
|---|
| The more numbers match, the more reliable the selection. Start with Bosch 0265216531 and 0273004337, then check 46479194. |
| Why do you not state the car model? |
| Because selection is by part numbers. The model is not confirmed here, so we do not name it. |
| How are the Bosch numbers written in the list? |
| As a string of digits without spaces. On your part they may appear split into groups of several digits - it is the same number. |
| I have similar but not identical numbers. What next? |
| Get in touch and give them in full. We will check whether any of our listings has exactly that set. |
