Re: won't shift out of park
Along with the two correct answers RE the shift interlock, it is possible to remove the electrical plug w/wires leaging to the unit without dropping any panels. Go in there with a needle nose and maybe a small screwdriver to release the lock.
*I unplugged mine back around the 5,000 mile mark and never looked back. IIRC it's right under the steering column itself, can't miss it!
