It wont go into reverse! I dont know why. I went over a pretty bad speed bump and after that it would not go into reverse. Anybody have any ideas on what it is? Ive heard that it could be the "neutral switch" wich is located somewhere under the shifter.

Yes,safety neutral switch is what you need to look at under the car,if its soaked in water and or corroded,then you need to either clean it up and seal it or replace it,if its too damaged.

Ok do you think its located in the shifter console like people say or maybe under the car?

The safety neutral switch is under the car...
