Lock up converter question

I have no correct answer for you.
Try looking up Mopar Action Magazine archives on line.
I remember several articles about locking converters, how they work and how to disable them.
Thanks but I’m not looking how to disable, but to understand if I know how they work and can keep it (lock up) without computer control. Most hot rod type info is how to disable the lock up which the more I learn is a horrible idea for a plain Jane passenger type vehicle.
