[Mgs] Determine build date for an O/D transmission?

As an interface designer, I am puzzled by the “push for on” solution. It seems somehow inappropriate as well as unnecessarily complex.

Overdrive seems to me to be a function where a clear on/off toggle is the natural mode of engagement. Sometimes I want it on, sometimes off, and I want to know which mode it is in.

But then, I think the “start button” on modern cars is idiotic. So YMMV.

In the case of my CBB it's sitting on the shelf on the passenger side of the heater box.  It's all solid state, has never given me any trouble.   I bought the thing on line a few years ago but I don't remember the name of the seller.  I absolutely love the thing!

That has a warning light to say it has been locked out, rather than one to say it is engaged.
