going for a "WAG" here.......... doesn't the neutral safety switch look and act like the old 727/904 switches ? three wires, center wire is ground for the starter relay, while the two outer wires complete the reverse light circuit ? [all contacting through the rooster comb of the valve body] then, there is the other connector[s] that control the overdrive and lockup, as well as the governor function in the electronically controlled [RE] transmissions ?

The N/S is an input to the TCM/PCM. When it doesn’t “see” the N/S it can cause loss of OD, other issues.

The1,2,3 shift occurs purely by hydraulics but O/D and L/U is electronic over hydraulic.
