Question Can I convert a manual p28 ECU into an Automatic?

I've been seeing these videos on how to convert a P28 (Or any 92-00 ecu) from an automatic to a manual, but i was wondering is it possible to do it the other way around? sorry for the ignorant question but I cant help but wonder, I see them removing two resistors and boom, its a manual ecu, but is it that easy the other way around? do I just solder on two resistors and boom, now it an automatic? I might even do it my-self for a future build.

I doubt the MT ECU has the programming to shift AT gears, but I'm not 100% sure. At least with the AT ECU with an MT, you'd have to override the shift commands to not throw a code. Just word vomit thinking it through..

I'm gonna go ahead and say that you can't, but again, not 100% sure.

The d-series forum would have a definite answer for you. They’re specialists with building d-series stuff.

No

even if it has the extra wiring sockets, you would need to open the case, remove the control chip and flash it with an auto program, or buy a flashed chip.
