Car is acting up after replacing neutral switch.
 

When I bought this vehicle. It would only start in neutral. So i bought a switch. Brought it to the mechanic to have them replace it. They replaced it however it's causing the following issue. When it goes into park it thinks it's in reverse, or it'll think it's in drive etc. They can't figure out why this is happening. They ordered a new switch and same thing, they put the old switch back in same thing. They say the bracket looks fine, cleaned it out, let it all sit and took time with it.

Any ideas?
