Looking for the same answer on 427 PCM. Never found anything in the wiring diagrams to support this theory. The 4wd 4L80's use the speed sensor signal from transfer output and have the transmission output shaft speed sensor hole dummy plugged. Something has to tell the PCM your'e in 4low but I couldn't ever find it.
