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 select an ABS unit for an Alfa Romeo 156 by number 0265216401?
Start with the symptoms and the fault codes from the tester, and finish with the numbers 0265216401, 46513088 and 0273004136. The unit is used, working and original.
Alfa Romeo 156: ABS 0265216401 / 46513088 - from diagnosis to comparison
The title of the listing mentions the Alfa Romeo 156, and only that model do we regard as confirmed. The unit includes the ABS pump and control module. Condition: used, working, original. Below we describe the route from noticing the symptoms, through checking the basic components, to comparing the numbers. You will also come across the same Bosch number 0265216401 and OEM 46513088 in other listings, so what tells them apart is the third number: 0273004136.
The numbers - the end point of the check
- 0265216401 - Bosch number: 0265216401
- 46513088 - part number (OEM): 46513088
- 0273004136 - Bosch number: 0273004136
It is 0273004136 that sets this listing apart from the others with the pair 0265216401 and 46513088. If your part has a different third number, you are probably looking for a different variant. So check it separately, without relying on the first two.
At the start of the journey: signals from the car
With the Alfa Romeo 156, drivers usually reach for such a unit when:
- the ABS warning light is on despite the main brakes working properly,
- after the key is turned the pump can be heard running briefly, and then a fault appears,
- the fault remains after being cleared and comes back after a short drive,
- the tester does not connect to the ABS control module.
Go to a diagnostic specialist with a specific question: do the stored fault codes point to the module, or to the sensors or wiring? Do not replace the unit without such an answer. Once the decision is made, plan for bleeding the brakes after fitting and ask whether coding will be needed.
