5.3 ls with 700r4
If you went 4l60e it has a VSS already bolts right up with stock 5.3L dished flex plate. Then all you would need is the CC box that's mounted on the fire wall in the trucks. And wire it up and that's it.
The only down side to a 4l60e is it requires an electric speedo. Or run a cable X box which is $$ for a mech one or even more $$ for mech speedo tail housings.

You just run the vss output from the LS pcm to the speedo output coming out of the DRAC module behind the glovebox.
This lets you ditch the drac and everything is fully controlled by the LS pcm.
I wasn't trying to sound like a ***** and make you change your mind just because it's an older tranny. But when you start trying to tie everything in and you want it to work factory flawless you can't go wrong with going the newer route. But I also understand having some coin tied up in your older tranny. But since it is built it should be an easy sale.

Tell whoever is building your harness you need a output signal wire from the pcm speedo output left with the wiring you have to tie into inside the cab.
Behind the glovebox you can get tach, speedo, check engine, brake switch signals, hvac request if you are keeping operational ac, and ignition to power your swap harness.
Tell them you want all of the wiring that needs to be run inside the cab to go through the factory firewall location below the puke bottle it will be neat and clean that way and you can hit all of the needed connections behind the glovebox

There is a single large connector behind the glovebox that contains all the needed wiring connections you need to tie into.
