W211 e220 problem transmission and horn/sbc
after using the horn for more than 3 4 seconds it turns off my sbc i tried several times and every time after honking i run out of brakes, turning off and on fixes it. this appeared after I replaced the automatic transmission of the car with a new one, at the same time the transmission when cold kicked and boxed the automatic is working, but for me it does not start normally, in parallel with the problem with the horn that shuts off the sbc. can anyone guide me as to what to look for as a problem because illiterate mechanics have led me to this point

Out Of Control!!
After reading your well constructed post my suggestion is to take the car back to your sisters brother who hopefully replaced the correct transmission but in doing so screwed up the electrics on the car---in other words fix the car

double check your Main GND Strap that is normally attached by a nut near the tranny flywheel.
