It could be either. The most common reason is that the shift interlock is stuck. look under your truck and disconnect linkage from the trans using a screwdriver. if you can move the lever on the trans the problem is the shift interlock. The interlock works of the brake switch, which is on the brack pedal rod. when you push the brake it cuts power to the btsi solenoid which unlocks the gear shift. usually the brake switch goes bad keeping the solenoid on. Try un hooking the battery and turning the key all the way on and see if it comes out of park.
