2006 Chrysler Pacifica P0700 Transmission Fault: No Movement in Drive or Reverse, Works in Manual Mode
I own a 2006 Chrysler Pacifica with a persistent transmission issue indicated by fault code P0700. The vehicle will not move when shifted into drive or reverse, but it functions normally when placed in manual mode. I have not used an OBD2 scanner to retrieve additional codes, and no other mechanical issues have been reported. The problem appeared suddenly while driving on the highway at 65 mph—after feeling a clunk, I stopped and found the car unresponsive in drive or reverse. I'm seeking advice on what could be causing this issue, especially given that P0700 typically points to transmission-related problems.
Could you confirm whether your Pacifica is equipped with a 3.5L or 3.8L engine? Have you checked the transmission relay and fuse #36 (integrated power module) located under the hood? These components are common points of failure in P0700-related issues, especially when the vehicle fails to move in drive or reverse.
