So in 2002 or 2003 the dakota stopped using 2 modules for the engine and trans and only have one PCM that controls both the engine and transmission. The P0700 is litteraly just a pcm code that tells you there are more transmission codes and you need a more advanced code reader to get into those a basic one won't do. Even though its all in the same computer its in a different section in the programming.I'm looking to troubleshoot a code that keeps coming up. I'm trying to help someone with information on it. I've got a 1999 Powertrain diagnostic manual for my 99 R/T Dakota but I'm looking for an 04. My friend has an 04 that he's had looked at by different mechanics for a P0700 code but it keeps coming back. The transmission works fine and is not slipping. It's when the check engine light comes on and it drops out of overdrive. The only code coming up is a P0700. I know the Dodge Dakota 1999 Powertrain diagnostic manual I have has helped me a lot but the 04 might be different because it has a separate TCM. Is there anywhere safe I can download the 04 Dodge Dakota diagnostic manual? I've found the factory 04 Dakota manual but not the diagnostic manual. Or is there a file section where it's located?
There's also a demi module IN the transmission on the solenoid pack. Which is most likely the issue. Mine did exactly what you are describing. Ended up being a solenoid in the trans going bad and it kept going into limp mode. Common issue in the 2003 and newer dakotas/durangos. The solenoid gets weak?? for lack of a better term and lets the clutch pack slip and you get a improper gear ratio code and trans goes into limp. The solenoids on the 545rfe are an all in one type of thing. Mine ran over $300.00
