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.

Transmission Control Unit A2C1924660101 – does it fit your Hyundai?
This is a used, working Continental transmission control unit with part numbers A2C1924660101, 954402DSR0 and SIM2K-305. The car model is not specified – the unit is matched by its numbers. Before buying, compare the numbers with the label on the control unit in your car.
Transmission Control Unit Continental A2C1924660101 – Hyundai
The transmission control unit (TCU) manages the gearbox: based on sensor signals it decides on gear changes and controls the gearbox actuators. This unit comes from a Hyundai; the car model is not specified, so it is matched by its numbers.
Part numbers to compare
- A2C1924660101 – control unit manufacturer number (Continental)
- 954402DSR0 – Hyundai part number, on the label: 95440-2DSR0
- SIM2K-305 – additional marking
The same numbers should appear on the control unit in your car. The car model alone is not enough – control units differ in software version and configuration.
Signs of a faulty transmission control unit
When the transmission control unit starts to fail, the most common signs are:
- gearbox limp mode,
- incorrect gear changes,
- a gearbox warning light or message,
- no communication with the control unit in the diagnostic tool.
Before replacing it, check the power supply, earth connections and connectors, and read the fault codes – other gearbox components can cause similar symptoms. After replacement, coding or adaptation with a diagnostic tool may be required.
