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 32481111802 – does it fit your Toyota Auris?
This is a used, working Aisin automated manual transmission control unit with part numbers 32481111802 and 8953012252. It fits: Toyota Auris (MMT gearbox). Before buying, compare the numbers with the label on the control unit in your car.
Automated Manual Transmission Control Unit Aisin 32481111802 – Toyota Auris
An automated manual gearbox (MMT) is a manual gearbox in which the clutch and gear changes are operated by actuators. The control unit (TCU) decides when to disengage the clutch and change gear and controls the actuators – the driver has no clutch pedal. This unit fits: Toyota Auris.
Part numbers to compare
- 32481111802 – control unit manufacturer number (Aisin), on the label: 324811-11802
- 8953012252 – Toyota part number, on the label: 89530-12252
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:
- inability to engage a gear or pull away,
- a gearbox or clutch fault message,
- jerky gear changes,
- no communication with the control unit in the diagnostic tool.
Before replacing it, check the battery and power supply – automated manual gearboxes are sensitive to low voltage – as well as the earth connections and connectors, and read the fault codes. After replacement, the gearbox usually needs an adaptation (including clutch bite point learning) with a diagnostic tool.
