Do these models have the 722.6 or 722.9 transmission?

You may have a serious uphill climb getting all the electronics to talk to each other.

For sure the engine controller, transmission controller, instrument cluster, and key switch all have to match.

722.6 the transmission controller is outboard of the transmission, and the transmission itself just has sensors and actuators. You will have to re-learn the adaptations but at least a different transmission computer will talk to a 722.6.

722.9 the controller is integrated into the conductor plate and locked to the VIN as stored in the other main modules.

I suspect the second level modules (air bag, SAMs, door controllers, seat controllers, entertainment) will not be as much a problem since they are not coded TRPs in EPC and I've heard of people swapping these modules with no issues without having to do SCN coding (the coding that has to phone home). Regular version coding in Xentry can be done with a cloned laptop and multiplexer since it does not phone home.
