I'm starting to have trouble starting my car when its in park. When I move the gearshift down to neurtral it then starts fine, so I know I either have a problem with bad shift linkage bushings or a bad switch. Does anyone know where the switch is? Is it outside on the transmission or inside under the center console?

Thanks.
