Didn't Ford say that there were new dies for the sheet metal (belt lines are subtly changed) and new (North American) suppliers for a lot of the parts?
While I don't work for Ford, I do work for a mfg company and have designed for competitors.
In between design stop and volume production is a bunch of small new product introduction batches where tooling and jigs are finalized and assembly documentation created. Usually done some where other than the volume plant. Which fits with these 2 Rangers.
Depending on what is being concentrated on/what is ready, trucking a 1/2 finished RoW Ranger from Mexico might meet the needs. And RoW Ranger would be as likely to have manual as not.
On other have the Getrag MT-82 from the Mustang bolts to the 2.3EB and has reasonable ratio spread. (no double OD, so you would probably be looking at 3.31 axles*, but we can fix that later).
*CAFE comes before performance.
