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.

Voyager (1996-2001): which ABS unit to choose if you have P04721427AE?
A used, working, genuine ABS unit for a Chrysler Voyager (1996-2001). Numbers: P04721427AE and four ATE numbers - details below.
ABS unit Chrysler Voyager (1996-2001) - P04721427AE
Let us start with the principle of operation. In an ABS each wheel has a sensor that sends a speed signal to the control unit. When one wheel slows down more sharply than the others, the control unit goes through three phases: it holds the pressure, reduces it, and then increases it again. The valves do this, while the return pump supports the whole process by moving the fluid. Our listing is for a unit from a Chrysler Voyager (1996-2001) with one OEM number and as many as four ATE numbers, which means the comparison has to be made with particular care.
Five numbers to check
- P04721427AE - OEM part number: P04721427AE
- 10051181861 - ATE number: 10.0511-8186.1
- 25020404504 - ATE number: 25.0204-0450.4
- 25020404513 - ATE number: 25.0204-0451.3
- 25094601793 - ATE number: 25.0946-0179.3
Two ATE numbers - 25.0204-0450.4 and 25.0204-0451.3 - differ only in the last digits and are given as separate references. We do not assign them roles; when ordering, compare them in full.
Signs that the problem lies in the ABS
The ABS unit is worth checking when the car has:
- an ABS warning light that comes on while driving or stays on after start-up,
- a module or valve fault in the fault memory,
- no ABS action under hard braking.
First check the wheel speed sensors, connectors and supply voltage, as these can also switch the warning light on. After fitting the unit, bleed the brakes and follow any recommendations for configuring the module, if the car requires them.
What to know before ordering
| Why are there so many numbers in the description? |
|---|
| Each of them describes a different aspect of identifying the unit. The more markings that match, the lower the risk of ordering the wrong version. |
| Which production years does the listing refer to? |
| The unit comes from a Chrysler Voyager (1996-2001). The numbers are what decide, though, not the year of manufacture. |
| Does a missing number rule out compatibility? |
| Not necessarily - not all the markings may be visible on the part. Write to us if you can see only some of them. |
| Is this part in working order? |
| Yes, used, genuine and working. The warranty period is given in the product features table. |
