Okay all, need some help. Just had the oil pan gasket and all bushings replaced on my F350 Dually. After they were all done, my 7.3 idi started and ran. Backed out of the garage and the E4od tranny would not go towards park, just towards 2 and 1, after the shifter was in those positions, it was stuck. I took off the Neutral Safety Switch/Transmission Gear Position Sensor and dropped the pan to find that the spring roller on the gear pawl was broken. I replaced it and reseal ed the tranny, refilled the tranny, reset the Neutral Safety Switch and not it will not crank. I was noticing hard shifts prior to all these repairs and the NSS is the original that came on the truck. When I reset the NSS, I put the tranny in neutral and lined up the indicators on the switch, then put it back on. The truck powers up, glow plugs come on, and you can hear them cycling, just no crank now. Should I replace the NSS? Is there any other ideas out there? Thank you.

 

I would try to jump the wires or something of that sort.

I can't help on the trans issue but the no crank issue sounds like a nss to me.

 

The neutral safety switch is part of the range selector. Top right of transmission. Do you have a shop manual?

 

you probably didn't line up the correct lines on the range sensor.remove it and have another look.
you'll know if it's off a bit first,by trying to start the truck in N.you can also try (gently) holding upwards on the shift handle into P as you crank.

i would describe it's location as on the drivers side of the trans,under the shift linkage.
"top right" to me would suggest the solenoid connector location.

 

Your right. I could see it in my head.
