Well guys this one is a brain buster. My truck kept saying range shift inhibited and IT DOESN'T MOVE IN ANY GEAR!!! I replaced the NSBU switch and still nothing happens but now i can see the little line below every gear. After i replaced the nsbu switch the truck threw 3 codes. P0748, P0763, P0768. I replaced the pressure switch and my buddy deleted the codes... so no more codes but still no movement.
