A new neutral safety switch was just installed in our 2008 Pontiac G6. Why would that have an affect on the mechanism which puts the car in reverse, drive, and park? The console arm is now extremely tight and harder to move, when trying to place the car in gear. It was not like that before. The repair shop indicated it should loosen up with use, but it doesn't make sense, as to why the install of the new switch would have thus type of affect.
Any help is appreciated.
