Funny that I never heard of the TranzX system before.
From what it looks like in the video it's (very) similar to what Shift4Me does, except that it uses a torque sensor.
First of all, concerning your question: a buzzer signal is highly recommended. It's needed to warn you when the shifting is being done, because you need to take the load off the chain for just a second.
The 40€ type control unit looks neat. The plus/minus and A buttons will probably just short one of the colored wires. So that would be very easy to control the Arduino. The plus/minus code is already there, you'll just have to write a little extra code to control the auto/manual behaviour.
Maybe somebody here can help you on how the display is controlled...
Good luck and keep up posted on your build!
