I have a 2004 Dodge Durango. Twice the Durango shut off by itself while in park, right after I started it. I thought I may have bumped the key. The 3rd time, I started the Durango, when back inside to get a few things. When i came out the Durango was off. I tried restarting it, nothing happen, no crank, no start. I also notice the digital shift indicator light was not light. All of the other lights on the dash worked, plus headlights, turn signals , etc.

The day before this happened, the check engine light came on, I took it to our local auto parts store. The guy checked it. The code was P700, shift solenoid. Before I could tell him not to cleared the code, he did.

We check the usual no start things: Starter, battery, and even checked the ignition for a short. Thinking of the code P700, we just replaced the transmission shift solenoid pack. The shift indicator is still not lite and still no crank and no start. We also replaced the PCM.

Any suggestions

 

You had the PCM flashed to work in your truck I assume?

P0700 is likely not even the real code, many times P07xx codes cannot be properly read by generic OBDII scan tools. I would start looking at the wiring to the transmission and look for broken/corroded wires. I would advise to never replace transmission parts simply because of a code and I also suggest not changing any more parts until you have some idea what is actually wrong with it. You run the risk of adding to the problem if you do.
