2ZR Compatible Transmission Help - Toyota Yaris Forums

That gets you most of the way there. There's also the issue of mounts and wiring compatibility. You'd need to get a subscription to Toyota's TechInfo system (a 2-day should be plenty) and download all the electrical wiring diagrams (EWDs) for both the donor and recipient cars to verify compatibility of the wire harnesses and ECU. The transmission itself should only have the backup light switch and the speed sensor (if it doesn't already use the ABS sensors) but you'll need the rest of the diagrams for the engine itself.

The EC6X option is something I've been looking at for a long time but there are very few variants of that available here in the US. Would definitely be interesting to see how to do it though!
