How would you check a neutral safety switch to see if it is bad?

The condition that will MOST-Likely cause hydraulic binding when foreign oil enters the wrong circuit is:

On an unmodified engine, intake manifold vacuum above 15" can indicate a mechanical problem.

A(n) ____________________ will tell if the transmission is experiencing internal leakage, has a problem with a vacuum modulator, or requires adjustment to linkages.

While having a discussion, Technician A says that when the vehicle will not move in forward or reverse ranges, the cause could be no hydraulic pressure. Technician B says that it could be a mechanical problem. Who is correct?
