Maybe there is a three wire ball switch? Cant remember any of the manual shift cases having more than one switch on them, but i'll dig around tomorrow and see what I can find. Come to think of it, i've even fixed a 98 model 4l60e manual shift transfer replacing the two wire ball switch same situation.
