Hey folks I own a 2002 P5 with just under 120000 miles on it. I have loved the car but the last few months have been a little rough for it. It is an automatic transmission and recently when I park I cannot shift past neutral from drive. I leave my foot on the break and everything but it will not go past neutral it is like there is something stopping it. I would love some help on what the problem is and if I can do it on my own.
