Crank position sensor or trans going out or shift selector

I noticed my truck do this about a month ago. It was shifting gears while I pulled out of a parking lot and it like stalled. Rpm redline but i dont move. Like the clutch got pushed in on a standard but i have auto. It's happened a couple other times. It did it on a hard acceleration from a stop up a hill. It seems to only happen in a lower gear 2 3 area.

Now my gear shifter sometimes doesn't seat all the way into drive and ill tap it up and you hear it go in but this is going down the road. Like it drives fine but it isnt in all the way like its out of sync.

When I put it into 3rd it goes to 4th. 2nd to 1st and 1st goes well.

It threw the crank code like a week ago. 0636? If I remember right. I just remember it was a cps code. Cleared and re read. Nothing. Hasn't come back.

I just about always have 2 trans codes. One for incorrect gear ratio and shift solenoid A.

And sometimes a po1000. Saying it didn't get to do a system scan or something.

It's done this like a total of 3 or 4 times. And the last couple have been closer together. Just trying to figure out what I'm gonna be saving up for.
