My shifter is stuck in park transmission shop said tranny is fine need answers

Turn your key 1 click, Before run position, do not turn ignition on. See if shifter will move. The brake switch has to work in order to release normally. If you can get it into neutral you can start the truck and tank it to someone to test it, unless you know how to test the brake light circuit.

repair brk lights and shift lock will work. poss brk light switch is bad
