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 does number 22611AA990 mean on Subaru engine control units?
Engine control unit 22611AA990 is a used electronic module that manages engine operation. It is intended for Subaru, and it is matched by the numbers in the listing, not by the car make alone. The listing does not state the car model or year, so we do not give them in the description and match the part by its numbers. The listing also gives the markings G6. They help tell the control unit versions apart, but the full part number is what decides compatibility.
Control unit numbers and markings
The numbers as written in the listing and as a single string, the way catalogues list them:
- 22611AA990, car manufacturer's original number.
Matching by number is more reliable than matching by car model. Compare all the numbers and ask us if any of them does not match.
Symptoms of a faulty engine control unit
- the car loses power or goes into limp mode,
- the engine jerks when accelerating,
- starting is blocked by the immobiliser after the electronics have been replaced or repaired,

Before buying a control unit, read the fault codes with a diagnostic tester and check the power supply, the earth connections and the connector. Damaged sensors, wiring or fuses can cause similar symptoms, and in that case replacing the control unit will not help.
