The automatic transmission control unit (often designated as TCU or TCM) is a crucial electronic component responsible for smooth and trouble-free gear shifting. Its failure, most often caused by overheating, short circuits, or water damage, results in jerking, an inability to shift gears, or the vehicle entering limp mode. Purchasing a new module at an authorized dealership is a massive expense, which is why replacing it with a fully functional, used original is the most reasonable solution.

What may point to a faulty ABS unit
An ABS unit is usually checked when:
- the ABS warning light stays on even though the sensors are fine,
- the control unit stores an internal fault,
- there is no communication with the module in diagnostics,
- ABS switches off under hard braking.
First read the fault codes with a tester, then check the wheel sensors, wiring, fuses and battery. After replacing the unit, the brake system needs bleeding. On some cars the module also needs to be configured.
