That has been on my mind and I think the seller knows this. I realize the seller is needing to get certain price but, there is a lot of unknowns at this point and not certain the seller & I can come to agreement on price at this point. But, anyways thank you everyone for answering my question. It appears last night, I found some answers regarding the transmission issues which can correlate to corrosion in a harness that communicates with the PCM as well. Anyways, thank you all again.
Can you point me in the direction of the harness corrosion issues so I can research it? My 04 Dakota is driving me nuts going into limp mode with transmission codes. Trans is getting rebuilt, but I want to eliminate all problems since it's a nice little truck that I need to be able to depend on with road trips.
Just circling back on the problem with my truck. I checked all of the wiring, relays, fuses, etc and found no problems there. Truck has a new 545RFE with all new sensors and shift solenoid and still had the same problem. Since the truck is almost 20 years old and has 230K miles on it, I decided what the heck....replace the ECM. TCM is integrated on this model. Solved the problem of it going into limp mode with a P0700 and P0750 codes and has not happened since. Truck ran great before, considering it is a 4.7, but I have even noticed it has more giddyup with the new ECM and gets slightly better gas mileage. Hopefully, this may help someone in the future. Remanned ECM was $300 in the link below.
