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.

Will ABS pump 3451676977801 fit your BMW?
Used ABS pump with control unit, number 3451676977801, inspected before sale. Matched by the numbers on the block and sticker.
BMW ABS pump: numbers 3451676977801 and 3452676977901
ABS module 3451676977801 is used and has been inspected before sale. It is intended for BMW cars, but whether it fits is decided by comparing the numbers with the original part in your car. The listing does not state the car model or year, so we do not give them here and match the part by its numbers.
Part number 3451676977801 and related numbers
You will find the numbers on the labels, while catalogues list them as a single string:
- 3451 6769778 01 (catalogue format: 3451676977801), BMW number of the ABS pump (hydraulic part),
- 3452 6769779 01 (catalogue format: 3452676977901), BMW control unit number.
Matching by number is more reliable than matching by car model. Compare all the numbers and ask us if any of them does not match.
Symptoms of a faulty ABS pump or control unit
- the ABS stops working, although basic braking usually remains functional,
- valve or pump motor faults are stored in the control unit memory,
- the ABS switches itself off shortly after the engine is started,
- on a slippery surface the wheels lock up noticeably sooner than they used to.
ABS faults should not be ignored, because without anti-lock protection the car brakes less well on wet or slippery roads. Diagnosis and fitting are best left to a garage with a suitable scanner.
Questions and answers
| Are the make and model of the car enough to choose the part? |
|---|
| No. A single model comes with different versions of the module, depending on the engine, year of manufacture and drivetrain. The most reliable reference is the number on the original pump. |
| Are the pump and the control unit sold separately? |
| In this listing they are a single module: a hydraulic block with the pump and valves, with the control unit attached to it. |
| Can I send a photo for a compatibility check? |
| Yes. Contact us and send a photo of the numbers on your original pump, and we will help you check whether this module will fit. |
| Is this a new part? |
| No. We sell used original modules, each one inspected before sale. You will find the warranty period in the product features table. |
Not certain this is the right module? Send us the numbers from the label on your pump and we will help you compare them.
