My old 4-speed 4R75W from 2007 was treated as "replace with factory rebuilt" as well by the service-policy company. I'd honestly rather have a warranted rebuilt from a shop specializing in transmissions than roll the dice on a local wrenchape who may or may not be good at transmission rebuilds and may or may not have a clean place to put transmissions together.
