There’s no way door locks are on the same circuit as AT solenoids. But it sounds like it could happen at the same time due to a compromised harness or wire. Unless you’re solid with electrical you need to give this to someone who is. I don’t believe it’s the ECU like another comment said. When a car cools it contracts and the gap between wires becomes greater creating an “open” or vice versa when it becomes hot the wires or other items expand and can “short”. If it was a short you’d likely have a blown fuse somewhere. You need a wiring diagram and to chase the door lock circuit. Likely something will present itself visually. Check wiring harnesses near spots that vibrate since they can run through.

The ball joint is the ball joint. It’s not a nickname for anything. It’s on your control arm. Often times it’s easier to replace the whole control arm instead of pressing out the ball joint.
