My 1990 4 Cylinder 4Runner has a shift lock override button on the console at the front of the gear indicator near Park. I got this 4 Runner from my dad who owned it from new. As far as I know, he never had to press the override button to select a gear. He only had to press the button on the selector knob. Now the shift lever won't budge without depressing the over ride button.
Does anyone know how to correct this?
