to my knowledege(maybe yours is more extensive than mine)computers don't read in negative or positive they read in digital(1 and 0, on and off)
I wasn't writing it in logic level, but I can waffle if you like: discreet binary low passing inputs from each shift switch to the ECU over ride the pullups creating a logic zero that is either/or inverted, filtered, conditioned and passed directly to a multiplexer, PIA port or dedicated I/O on the micro controller where it is digitally processed according to the program, algorithms and closed loop routines in combination with other analogue and binary signals. The discreet binary outputs presumably with flyback circuitry control the shift solenoids.
The park and neutral binary low states are also sent through an OR gate via parallel circuitry, so that either one of the signals operates an inhibitor relay.
Did I tell you I can design industrial controllers too. Goddam I can walk and chew gum at the same time. Quick someone pat me on the back coz my head is stopping me from doing it myself.
DSMer did you spot the deliberate mistakes?
