The other night my truck got stuck in park. The shifter would not budge at all. Replaced the brake position sensor. As well as the transmission shift interlock solenoid. Now the truck shifts, but its shifting without pressing the brake pedal at all. Anyone have any insight to this?

Does your bake lights stay on all the time?
Now the lights are off. The left brake light has stopped completely. But the other side functions properly. Still shifting without foot on the brake.

It would indicate that you brake switch or bcm is out of adjustment or bad. You transmission is controlled electrically, not mechanically. So it's getting the signal that your foot is on the brake pedal and is being depressed, when it actually is not.
