Transmission Control Module (TCM) & Main Control Valve Body
The transmission control module (TCM) and main control valve body is a combination of hydraulic and electronic control units. Both these modules are installed in the transmission, in the fluid pan.
This technical principle has the following advantages:
- Minimum tolerances (TCM is mated to solenoids).
- Better coordination of gear shifts.
- Increased refinement.
- Optimized shift quality.
- Good reliability, since the number of plug connections and interfaces is reduced.
