Will a bad knock sensor prevent an engine from shifting?
A bad knock sensor would illuminate the check engine light and allow the engine to ping (spark knock). The engine doesn't shift, the transmission shifts.

What problem could the knock sensor cause on your car?
If the knock sensor failed the CEL (Check Engine Light) would be illuminated and the engine may "ping" or "spark knock" under load. Serious "spark knock" can damage the engine if allowed to continue.

Will burning regular gasoline in a 3800 series ii supercharged engine cause the check engine soon light to go on?
Yes it will cause your engine to detinate or knock, especially in warm conditions Higher octane gas has a higher flash point, it won't explode from heat and pressure as lower grades can.

You need to test/replace the knock sensor. ireplaced it already.
Can higher octane gas reduce engine knock or reduce NOx emissions?
It will decrease engine knocking or pinging associated with detonation problems, and will posssibly burn more efficiently. It can, but if a higher octane fuel reduces or gets rid of engine knock and/or ping, I would recommend taking your vehicle to a mechanic for diagnosis. Moreso, if you have a Check Engine Light on even. It's possible that you have some carbon build up in your fuel system that is causing the knock and ping. As far as the Nitrous Oxide Emissions being reduced from higher octane fuel, I have no idea. But most owner's manuals outline which octane to use, and wouldn't recommend swaying from their recommendation.

Not necessarily.
Transmission warning light?
The transmission warning light indicates that you have a late model vehicle, usually if the trans light is on your ck engine light is on too. On late model cars the trans has a brain box, it monitors a number of things and it now determines when the trans needs to shift to another gear. The brain box also looks at live readings from the trans and compares them to a group of set parameters, when the perimeters are out of spec. the check trans light comes on. Another thing to think about is that the engine brain box and the trans brain box talk to each other and compare notes
