A few automatic transmission questions and ideas

Do the latest automatic transmissions have any mechanical linkage between shifter lever and the transmission?
I'm guessing they don't though.

I was thinking what if I intercept the signals from selector lever to TCU (transmission control unit), and let it go into Neutral automatically when I'm coasting and put it back to Drive as soon as I accelerate. Of course there are many other cases to consider but you get the idea.

I looked into intercepting or overriding TCU but that seemed too difficult with modern ATs but faking the driver input seemed to be easier.
