What to do when the gear is stuck in park on a Honda 2001
My 1998 Honda Accord LX was getting stuck intermittently in Park. I found that the switch that turns on the brake light when you press the bake pedal was going out. This switch is $32.00 at any Honda dealer and most importantly YOU can change it yourself. Ironically, that same switch activates the gear shifter pin that lets you take it in and out of gear.
