Can't change the car shift gear into drive even when pressing the brake pedal. on 1994 Toyota Camry

When the special shift gear release button is pressed, the gear can be moved to drive. What needs to be replaced and how to do it. Thank you.

possibly a shift lock solenoid problem. ck for pwr 1st after brake pedal is depressed, if no pwr ck break light switch
what part am I checking for power and how do I do that?
TEH BRAKE LIGHT SWITCH UNDER THE DASH BY THE BRAKE PEDAL, USE A TEST LIGHT OR 1ST CK TO MAKE SURE BRAKE LIGHTS ARE WORKING
