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.

I have an old ABS unit in front of me - how do I check whether this is the one?
The answer is short: by the numbers. We offer a used, working, original ABS pump and control module unit for an Alfa Romeo with numbers 0265225193, 46840337 and 0265950086. We do not state the model - selection by part numbers.
Alfa Romeo - ABS unit 0265225193: questions and answers when comparing an old part
- I have a faulty ABS unit from an Alfa Romeo in the workshop. Where do I start?
- By copying the numbers from your part. Our unit is used, working and original, and the listing shows three numbers: two Bosch and one part number (OEM).
- And the car model?
- We do not state the model - selection by part numbers. That is why any discussion of compatibility always ends with the list below.
What is on the list and how to read it
- 0265225193 - Bosch number: 0265225193 (written with spaces: 0 265 225 193)
- 46840337 - part number (OEM): 46840337
- 0265950086 - Bosch number: 0265950086 (written with spaces: 0 265 950 086)
If you see the same strings of digits on your part, only separated by spaces, it is the same number. We do not decide which of the numbers belongs to the pump and which to the control module - what matters is that the whole set matches.
What customers come to us with when they need a unit like this
The most common fault descriptions are these:
- the ABS warning light comes on right after the engine is started,
- the diagnostic tool does not connect to the ABS module,
- the pump can be heard running at moments when it should not switch on,
- the brakes work, but the anti-lock system is switched off.
Before you order, it is worth reading the fault codes and inspecting the wheel sensors and connectors. After the part is replaced the brakes must be bled, and the workshop may need a tester for any coding.
A chat at the counter: the most common questions
| Which of the three numbers is the most important? |
|---|
| None is more important than the others. First check 0265225193 and 0265950086, then the additional number 46840337 - a match on the whole set is the most reliable. |
| My number has spaces and yours does not. Is that a difference? |
| No. Spaces are just a way of writing it. Remove them and compare the digits alone. |
| Is the unit in working order? |
| Yes, it is a used, working, original unit. We give the warranty period in the product features table. |
| What if I only have one of these numbers? |
| Get in touch, give us that number and describe what you have in front of you. We will check it against the listing before you buy. |
