So far I have been able to verify that the "inhibitor switch" function and connections are the same pinout and plug shape. Actually it looks as if every automatic from day one (legacy+), no matter the model, uses the same switch.
This is the unit on the passenger side of the transmission that the shift linkage connects to. Its what lights up your dash and tells the TCU what selection you are in.
Working on the transmission electronics side. Looks as if at least one difference would be the torque converter turbin speed sensor (not needed) and the speed sensors. Also the plug is a different shape I think.
I SO wish I could get the the body side of the plug plus 8 inches of wire
I still dont think its correct, even if it is from subaru. Basically it would be like a standard 5 speed viscous center, with one output geared higher and a clutch to lock the viscious unit (like in some previos generation 5 speeds.)
Im still very sure that it has 36/64 front/rear at 100% duty and either 50-50 when turned off or 40-60 when turned off. Too much information exists to disprove the above document.
