Transmission failing to disengage

Transmission failing to disengage
Hey guys,
So I can't find the thread from a while back so I've got to ask the question again (sorry).
Necessary info: 2001 4x4 545RFE (auto) transmission
So the issue is, when I apply the brakes regardless of force (light, hard). The transmission some times fails to disengage automatically and will "wind up" persay. It always does in the end but it isn't nearly as responsive as it should be. I think someone had say it was an issue with the crankshaft positioning sensor, and it needed to be replaced. Can anyone help me out?

I will look into the speed sensor, I haven't gotten it out on the highway to test it at higher speeds recently (I just got the truck back). But I'm starting to think my abs system is acting up or my rotors are more warped (leaning towards rotors). Because it is braking weird now; this is a newer development.

Well the torque converter is what "disengages" an automatic transmission when you apply the brakes, it's why you can creep so much easier in an automatic as opposed to a manual. Without burning out your clutch, a manual is either on or off, and you will always move at idling speed at the very least (without bogging your engine down) when in gear. The torque converter takes the place of the clutch pad and pressure plate in an automatic, and is operated by fluid inside it. In some torque converters there is a clutch pad inside it that will engage whenever you are cruising steadily at a particular speed, so it could be that not releasing, or it could be a million other things.
Maybe take a video so we can see what you mean by "winding up".
