My Crown Vic is a 2008 police interceptor model. I haven't ruled out a parking brake malfunction. That would probably be the easiest fix. A friend of a friend said his 90s model crown vic had a reverse lockout solenoid known to cause bizarre problems. I'm just getting up and having coffee. I haven't called my mechanic or the business associate who sold me the car yet. That can wait til after my third cup of coffee. Here's hoping that I don't need a new transmission. Big expenses don't come easy for a small one car taxi company.
