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.

What information lets you safely match the ABS unit P04721453AC?
A used, working ABS unit with pump and control unit for a Chrysler: P04721453AC, ATE 25.0206-1155.4 and 25.0926-4353.3, and an additional reference, 00402775E000.
ABS unit P04721453AC for Chrysler - ATE numbers and markings
Let us look at the system from the hydraulics side. Fluid from the master cylinder goes to the valve block, and from there to the individual wheels. When the control unit detects locking, it cuts off the supply to that wheel and releases some of the fluid into a chamber, from which the return pump sends it back into the circuit. This movement can be heard as a characteristic buzzing and felt on the pedal as pulsation. The unit on offer comprises the pump and control unit from a Chrysler-brand vehicle; we do not state the model, because the numbers decide.
The set of numbers for this unit
- P04721453AC - OEM part number: P04721453AC
- 25020611554 - ATE number: 25.0206-1155.4
- 00402775E000 - additional reference given in the listing: 00402775E000
- 25092643533 - ATE number: 25.0926-4353.3
The additional reference 00402775E000 is supporting in nature. A similarity between part of its notation and other numbers does not mean compatibility, so always compare the full set.
When the ABS stops working
It is worth taking a look at the ABS unit if you have:
- an ABS warning light after the engine starts,
- an entry for a hydraulic module or electronics fault,
- no ABS intervention on a wet or slippery surface,
- no communication with the control unit.
Start with the wheel sensors and the power supply, as these are the most common and cheapest causes. Fitting the unit requires bleeding the system, and in some vehicles also programming the control unit.
