2002 dodge intrepid has a diagnostic oced of P0700. What would that be? Thank you

P0700 - Transmission Control System Malfunction.
Basically what that means is that a malfunction has been detected in the transmission and associated components.

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.

Hope helps (remember comment and rated this).
