Is it throwing any codes? A bad crank sensor can throw tons of codes.
Also for a point of clarification, we're talking about
crankshaft position sensors but we've also talked about distrubutors and sensors...the
camshaft position sensor is inside the distributor, the
crankshaft position sensor is on the upper bell housing. Both are abbreviated CPS so let's make sure we're all talking about the same thing. And both things can give you the symptoms you have.
The parts are very similar (
@U8MYDZT and I have a lot of very recent intimate familiarity with this trans) but you should have a 32RH based on your profile, since you have a 4.0. The 30RH came on the 2.5L. The naming can be very confusing, but so long as you're not messing with the input/output shafts or gears, you can safely call it an A-904 or A-999. You'll find very little info out there on the 32RH, but start searching for 904 and you'll find everything.
But as has been stated above, there are no sensors in this transmission. The only electrical components are the neutral safety switch (which only affects the ability to spin the starter) and the torque converter lockup solenoid, which I suppose could be accidentally locking up the TC too soon and maybe could result in stalling at low speeds?? It's not super hard to just unplug it from the trans, above the back driver's corner of the pan. It won't hurt to run with that unplugged; mine didn't even work for the past year. In the interest of isolating variables, I would disconnect it and only re-connect it after you've resolved this. I also tend to lean toward PCM problems as a last resort, but DO NOT let your shop refurb your unit. Contact
@Wranglerfix before you do anything PCM related, I implore you. (especially a shop that wants to replace your "governor sensor."
Probably should've asked this at the top of the thread, but when it stalls, describe what it does. Are there noises? Or does it just die? Does it happen at speed or only when stopped or nearly stopped? You said you lose power, does that mean the jeep is under-powered or have you lost all your gauges? Dash lights too? Let's zero in on exactly what happens when it happens.
