P0700 on a 2006 Dodge Charger
The engine light came on on my 2006 Dodge Charger 5.7L and the diagnostic readout indicated a PO700 reading. What could be the possible cause of this problem? Also there were several other codes that were present and they are listed below: U110C U141 U1403 U1411 U110E U110F U0100 U0103 U0002 U0121 U0700

Hi Thomas. The code P0700 is described Transmission Control System Malfunction. Basically what that means is that a malfunction has been detected in the transmission and associated components. There is good news and bad news. The good news is it might be covered under warranty. You didn't say if your vehicle is still under warranty, be aware that you may still have warranty coverage on this since your car is just 3 years old. The bad news is that the P0700 code really means that there are transmission-specific codes that you can't access with a regular code reader. There is a part called a TCM - transmission control module that works in a similar way to your PCM. The TCM handles the transmission electrical "stuff" and it stores further transmission codes.
If you want to pursue the issue yourself, you'll need to get your hands on a higher end code reader, or take it to the dealer or a transmission shop to get the actual transmission trouble codes read. Personally we recommend you get a shop to read those codes for you. The other codes are communication codes, we recommend you clear those codes after you fix the P0700 code and see if they come back, they could be related to the "main" transmission issue. The other good news is the fix for this may just be a software update that the dealer can do. Good luck!
