i just broke something in the shifter now i cant get it into reverse! the shift knob turns now. it sounded like something plastic (shear pin) had broken while trying to put the car in reverse. i usually rotate the shift knob clockwise while putting it into reverse otherwise it is difficult to engage. nobody that has tried to drive the car has been able to get it in reverse. kinda like my own anti theft device. but anyway. does anyone know what broke? fixxes? thanks!!!
