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.

Throttle Body RF7J136B0C – Mazda 6 (GG)
In a diesel engine the RF7J136B0C throttle body does not control power – it closes the intake when the engine is switched off to reduce shaking, and in many engines it also assists exhaust gas recirculation (EGR) control. According to the product data, it fits: Mazda 6 (GG); engines: 2.0; production years: 2005–2007.
Part numbers to compare
- RF7J136B0C – also printed as RF7J 136B0 C
The same number – RF7J136B0C – should appear on the label of the throttle body in your car. The model name alone (Mazda 6 (GG)) is not enough – throttle bodies with other numbers were also fitted to these cars.
Symptoms of a worn or faulty throttle body
Typical symptoms of throttle body problems in Mazda cars:
- soot from the EGR system on the flap – sticking flap, fault codes stored in the engine control unit,
- failed motor or position sensor – engine warning light, limp mode,
- flap not closing fully – the engine may shake when switched off.
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.
