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.

Possible signs of a fault
Drivers usually report:
- an ABS warning light visible immediately after the engine starts,
- a stored fault for one of the valves,
- ABS not working, along with ASR or ESP.
The first step should be reading the faults with a diagnostic tool and checking the wheel speed sensors, wiring, connector, fuses and battery. Once the unit is fitted, bleed the brakes and – if the car requires it – code the control module.
