Won’t go into gear, I replaced two fuses to get dash lights out. And one fuse let me use the over ride to put it in gear. But that gets old for reverse and drive.
It could be bad ignition switch or brake light switch. My first guess would be bad brake light switch.
Check the brakes on the back even though that is not the best test. Because the brakes may still turn on, but the shifter may still not release if the brake light switch is defective.
