Changed the front rotors, pads, rear pads and drums, bled everything, but now i can’t get the trans out of park? Why? If i d/c the battery, it’ll shift and i can drive it . Brakes are hard when engine not running, maybe too spongy when running. What gives? Anybody know?

Sounds like unrelated problems, though both involve parts of the brake system.
The transmission has a shifter interlock which requires the brake pedal to be depressed before shifting out of park. There is usually an override to the interlock. Next time it fails to shift I would try the override, if so equipped. Also, from what I've read this failure may also affect the brake lights so check to make sure they are working.
The fact the pedla is spongy means either there is still air in the system or the master cylinder is failing. If the master cylinder got dry while changing or bleeding the brakes, ther emay be air in the ABS unit. This truck has rear ABS brakes with 4 wheel ABS optional.
