I have a 2006 2500 Dodge Ram diesel and I can't get out of park. Already replaced the line from the shifter to the tranny and still can't get it to change gears. someone told me there is a brake sensor that allows you to change the gears where is it located

this is a sad problem on a nice and valuable truck- if it is a 2 wheel drive, it can be towed from the rear- fortunately- unfortunately, you are trying to fix something that is best done by an expert- it will be more cost effective to take the truck to a good mechanic- it might be as little as $100- why go through all that? If this was an old pickup, sure, fix it yourself- but it is a nice, new truck! just an old guru's opinion
