Q: The truck won't shift out of park so thinking that it's the park shift interlock solenoid? Is that a good possibility that's what

Hi there. First thing to check would be, whether the brake lights are functioning at the time it won’t shift out of park. There is a possibility, there is a poor connection at the fuse. It could be, a faulty brake light switch not supplying power to the shift interlock solenoid. There may be, a poor connection or wiring concern. It could be, a faulty shift interlock solenoid. I recommend having your vehicle’s shifting issue be diagnosed and repaired by a certified technician, such as one from YourMechanic.
