Our 2005 Chrysler Town and Country, 3.8L V6 threw these codes and went into limp mode. After researching, we felt confident that a solenoid pack would take care of the problem. My husband installed a new one and things seemed fine for about 2 weeks. Then suddenly, it went into limp mode, throwing the P0700 and P0755 codes again. Anyone have any ideas what else could be causing those? Any help would be much appreciated. Thanks. We are baffled.

 

Possible your solenoid is away again due to earthing wires connecting trans to body modules. There is a few issues on here regarding this. So check all wires especially ones near exhaust pipes.

 

Thanks. We have been wondering about wiring. Will check that. Hoping we didn't fry the new solenoid pack.

 

possible wire issue or u got cheap parts

 

Bought Chrysler OEM from a dealership.

 

then wire issue more then likely
