Can you give a little background on the problem, how long it has been sitting before this happened would be good, anything else like that. Yeah I think this is a 722.6 trans so the shifter module could cause a no-start if the TCM doesn't think you are neutral, the NSS is part of the shift lever. Never heard of a code like that, you got any codes in engine management, that must be a trans code. I assume the idiot lights are coming on, just no crank? Will it shift out of park if you turn the key on and step on the brake? If so try starting in neutral. The shifter never got wet recently did it? Rain, coffee, soda??? Any borrow the car who might have dumped something on the shifter? This is famous for happening, the shifter hates strange drivers and sucks on their drinks I guess

What do you mean ECU reads error? You mean in the odometer section in the instrument cluster????

Where is the code "0700" is that in the trans control unit???

Will the shift lever move out of park? (I know the engine isn't running, but say if you wanted to put it in neutral and push the car can you do it? Without doing the manual override?).
If you turn on the car (ignition switch to on) and step on the brake will the stop lights work (I know sounds unrelated, work with me here).

Do you get all the normal idiot lights coming on when you turn the key to on?

Strong possiblity, (I thought of this later, after I answered your first question) is the ignition switch, these are the cassette-style ignition switches and are prone to failure, although never heard of one make the engine quit, but definitely cause a no-start.

Need to answer questions before I can move on.

What module has a code 0700, not familiar with a code 0700 so want to know if that is from the ecu or trans module (etc), not sure why you say the code was read before it died, why were codes even being read before it died? See what I mean, this is confusing.

No I wouldn't pull out the ignition switch yet, based on what I am reading.

I would jump power to the starter solenoid and see if it will crank.
Or you could turn the key on and see how many dead fuses you have that would involve the control units.

You might also investigate blown fuses elsewhere, there should be either a base module or a K40 relay that has fuses in it, usually in the area of the right read underhood area, usually under plastic covers.

Nah, there's no way low fluid will prevent a start (or cause the car to stall). You could dump all the fluid out of the trans and it would still crank and start, makes no sense at all.

On the no crank, given what has happened at this point, I'd still guess the ignition switch.
Normally I would assume it's the starter solenoid due to the no-crank problem, but this wouldn't explain the fact that the car actually quit running. Quit CRANKING yes but not the stall. Plus the cassette style ignition switch is a fairly well-known problem.

Still curious if trans control unit is actually the shifter. On a 722.6 it really is a control module. Does your car show what gear you are in in the instrument cluster, or only by looking at the shifter itself, because if it shows in the instrument cluster I'd be interested in knowing of it shows you are in P. You could also try putting it in neutral and try starting it in N.

If it is shifting fine once you start it I would go along with that, the shifter can put the trans into limphome mode pretty quickly, so if all is well with the trans once you start it I think you are correct.
