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.

Common throttle body faults
Typical symptoms of throttle body problems in Opel cars:
- worn track in the throttle position sensor – fluctuating revs, jerking on light throttle,
- carbon deposits on the throttle plate – rough idle, engine stalling when coming to a stop,
- in electronic throttle bodies: failed motor or gear drive – limp mode, reduced power, engine warning light.
When measurements or fault codes confirm the problem and cleaning has no effect, the throttle body is replaced with one carrying the same number. After replacement, many cars need an adaptation in the engine control unit.
