I'd be satisfied with the ability to force an earlier shift, and lock-up, on the 4R100 auto on our 2000 F-250 7.3L. As it is, it does not shift to OD, nor converter lock-up, until about 40 mph even when there is virtually no load. If I had a manual, I'd be short-shifting around town while running empty.

There at least used to be (likely still are) products on the market that can allow the driver to dictate TC lockup. Maybe Banks Trans Command, something like that? Can't speak to their cost or quality but they do exist.
When I had my 2002 7.3L I always had a feeling that the stock 4R100 left some performance on the table and if I'd have kept it a built trans would've definitely been in the plans.
