I have an 07 Commander 5.7 I bought used, so I don't know it's history. I rebuilt the engine and changed all fluids,filters,sensors with Mopar units. Mainly, if the battery is disconnected after reconnecting and driving for about 1 to 2 miles a shudder starts and the farther you go the worse it gets. I think if you kept driving it at this point it would eventually destroy something. That's how bad it gets. To stop it, I have to pull over, turn off the ignition and restart. It may be fine for a few miles, or the entire day. I have replaced the final drive control module with a new Mopar unit and checked everything I can think of with no change. It is certain to do it in a short distance after a battery disconnect, but occurs at random times after being restarted. I replaced the fluid in both diffs with the prescribed Mopar type. I have also replaced all 4 wheel speed sensors with Mopar units thinking it may have something to do with the ABS system, as well as the input and output trans sensors. The PCM engine/transmission computer has also been replaced with a rebuilt unit, but acted exactly the same as the original computer. It feels like something to do with the all wheel drive. I was hoping someone else may have experienced this and has found a cure. There is no check engine light or codes set, as I have checked with scanner. Any help would be appreciated!!!!
