Five Trany Codes at once
Got a couple codes that told me my NSS wasn't working not to mention it was difficult to start, even in neutral... I forget what the codes were now.
Anyhow broke the old NSS taking it off, bought a new one, put it on and the jeep will not start. Turns over, no spark and a bunch of transmission codes:
P0705
P0743
P0753
P0320
P1694
I've looked them up and they all appear to be circuit related.
I don't see any wires ripped apart or bare but it is really weird that these all showed up at the same time after messing with the NSS.
I also unbolted the coil trying to figure out why I didn't have spark so I undid the bolts holding the four grounds at that location. I have since cleaned everything and put it back together the way I found it.
I've read some threads related to a couple of these codes but didn't find anything that covered them all at once!
Any help would be appreciated.
Thanks
Justin

For right now I’m going to assume the trans codes are history codes that need cleared . However the other codes scream bad crank position sensor . That’s where I’d start if in a hurry is a mopar CPS.

swap the crank sensor from that other Jeep if it is also compatible . We can address the hard codes with the trans once it’s running again.

Hey Thanks GreaseMonkey17 you were right about the crank sensor. I assumed because all the codes showed up at once it was the same cause... apparently not. A guy at work told me the same thing a week earlier haha. Anyhow, it runs and it shifts and everything so I don't know why the tranny codes keep coming back. Maybe my little code reader won't clear them properly.
Good for now,
Justin
