Your Automatic trans and ABS/TC both have different ECUs from the main one.

Most engine compartments are faraday cages just incidentally

It would be much easier and cheaper by a huge order of magnitude to buy/make your own universal controller. Manufacturers can't prevent it (you can watch all CAN messages your car sends through the OBD2 breakout and theoretically identify them eventually with something like a Kvaser memorator) but it would be a massive time sink. People who make universal/independent scan tools have to do this and they are able to charge large subscription fees if they are successful.

curious, the signals the controllers output to the parts of the car to actually control it, are they digital & message based like CAN bus, are they PWM, or are they analog signals?
