2005 Volvo V70 wagon Stuck in park, then won't go back to park position to allow me to turn the car off. I had someone clean the debree out of the gear shifting area and it was fixed for 12 hours, now I just need to figure out the name of the part that tells the car it is in park or not, ..... Shiftlock... sensor, I don't know

A link to buy would be awesome

Also, can I override it?
