The E8x 28I uses a GM sourced AT, and that particular piece is made in France. It has nothing to do with the ZF units that are mated to N54s.
PS 19/21 is just nomenclature, they are the same transmission. The HP26 is the higher torque version that got tossed into the 35D. We’ve looked into a swap but the bellhousings don’t match up IIRC.
