My 02 did same thing. On the passenger side of the transmission output is a sensor. That is the “speed sensor“ if you will. I found I had no base signal coming from the control module. Upon further inspection I had a mouse chew on top of transmission transfer case etc.

Check the main engine ground on the back of the block near the firewall. You should be able to see it from the underneath the truck, it is up near the top of the engine just below the oil pressure sensor. Otherwise you will probably have to remove the intake which is a pretty lengthy job. When this happened to me it gave all kinds of weird electrical issues on the dash and it wouldn't crank at all - just clicking like a low battery or a bad starter

Yes I checked all grounds and I could possibly find and those are good. Currently hunting down a used fuse box cause I’m too cheap to buy a brand new one for almost $500
