I am in a immediate and desperate need of advice and possible problems/solutions. Put my 94 LS400 into park at a parking lot and heard what sounded like a small and quick scratch, but I did not hit anything. When I get back to my car, it will not shift into gear. Everything appears to be fine, no warning lights are on, and I can hold the button to shift into gear down. However, it won't let me shift no matter how hard I push and pull. Brake lights do not come on even though I'm on the brake pedal. Tried having a friend push and shake the car while I tried to shift into gear, but no luck. PLEASE HELP ASAP! What would cause brakes to quit responding, and what could I do to solve this problem. Thanks.
