As for a conventional automatic you can lock up the tc while its shifting, but the harmonics and stresses are a great way to break the input shaft.
I knew of guys at one time who use to rig up switches to lock the tc for performance. Sometimes you got away with it, other times it wore out the lock up clutch and with bigger engines it broke the engine.

In CVT there are positions where pulleys stop to "create" gears. Our brain is just to used to gears this is why engineers don't want to reinvent the wheel. They can program cvt to use different positions to kinda mimic gear shifting.
As I said right at the beginning I use this "smart switch" for low power low speed conditions only. This is why I posted it here where people are trying to squeeze extra mile from a gallon of fuel. Locking TC at low speeds will improve your gas mileage. Your auto transmission will be like manual. Auto transmission leads to higher fuel consumption because of slippage in TC.
