On reflecton, I think there are two vss's, one on the tailshaft of the tcase front output shaft, rearward side of the case, for 4wd detection? gen 1 had one there...

Then I think there is a second one on the tcase rear output shaft, a 4pole pulse generator. It provides inputs for the speedo, odo, and TCM which controls o'd function, a likely culprit.
