Mechanic told me I needed new NSS for no-start issue. Can the NSS be bypassed?

No, you cannot bypass it. It controls a lot more than just the starter circuit. It tells the computer what gear it is in so the computer can make decisions.

Where is the neutral safety switch on a 2001 chevrolet impala located? I was told inside the transmission. That the transmission needs to come out to replace it. I'm about 99% sure thats incorrect. So "Help".

The park / neutral position switch is located INSIDE of your vehicle's transaxle and it will require a lot of labor hours to replace.
