I did my own machining and added the speedometer drive to my 4l60E tail shaft.
One of the few inexpensive conversions I could do myself.
For a 4L60E can't you just use a 700R4 tail housing to get a speedo gear? Or is there an early/late case difference?

And 4L80E was used in some 1990ish diesel pickups that had a stand alone controller. Yet I never see anybody do it that way. Is it because the controllers are hard to find or don't interchange with later transmissions or why?
