    Vss for shift points, or the tranny will mechanicaly shift=clunk. PLus other sensors see things moving but not your speed so the engine will stall out. My wrangler did that when the mechanical speed sensor wasn't in all the way

    It is on the transfer case right? So no, you can't tune it out.
