I'm working on a friends car right now and dealing with the same problem coupled with the engine,ABS,and security light coming on. I removed the battery, charged it, and reinstalled the battery. This cured the problem for two starts and returned back to original problem. Cleaned all visible electrical connectionsand grounds. To shift out of park, remove the shifter boot and frame with a couple of screwdrivers from the console. Step on brake and reach into console and pull white lever up. Shifter should now shit into gear.
